This SDK helps developers get started with the on-chain tools provided by Metaplex. It focuses its API on common use cases to provide a smooth developer experience.
⚠️ Please note that this SDK has been implemented from scratch and is currently in alpha. This means some of the core API and interfaces might change from one version to another. Feel free to contact me about bugs, improvements and new use cases.
Please check the Sample App.
From Xcode 14, you can use Swift Package Manager to add Metaplex-iOS to your project.
https://github.com/metaplex-foundation/metaplex-iosIf you encounter any problem or have a question on adding the package to an Xcode project, I suggest reading the Adding Package Dependencies to Your App guide article from Apple.
The entry point to the Swift SDK is a Metaplex instance that will give you access to its API.
Set the SolanaConnectionDriver and setup your environment. Provide a StorageDriver and IdentityDriver. You can also use the concrete implementations URLSharedStorageDriver for URLShared and GuestIdentityDriver for a guest Identity Driver.
You can customise who the SDK should interact on behalf of and which storage provider to use when uploading assets. We might provide a default and simple implementation in the future.
let solanaDriver = SolanaConnectionDriver(endpoint: RPCEndpoint.mainnetBetaSolana)
let identityDriver = GuestIdentityDriver(solanaRPC: solana.solanaRPC)
let storageDriver = URLSharedStorageDriver(urlSession: URLSession.shared)
let metaplex Metaplex(connection: solana, identityDriver: identityDriver, storageDriver: storageDriver)
Once properly configured, that Metaplex instance can be used to access modules providing different sets of features. Currently, there is only one NFT module that can be accessed via the nft() method. From that module, you will be able to find, create and update NFTs with more features to come.
Lets dive in nfts module.
The NFT module can be accessed via Metaplex.nft and provide the following methods.
findByMint(mint, callback)findAllByMintList(mints, callback)findAllByOwner(owner, callback)findAllByCreator(creator, position = 1, callback)findAllByCandyMachine(candyMachine, version = 2, callback)createNft(input, callback)All the methods return a callback. It's also possible to wrap them inside either RX, an async Result or Combine. We only provide this interface since it's the most compatible without forcing any specific framework.
The findByMint method accepts a mint public key and returns NFT object..
let ownerPublicKey = PublicKey(string: "HG2gLyDxmYGUfNWnvf81bJQj38twnF2aQivpkxficJbn")!
let nft = metaplex.nft.findByMint(publicKey: mintPublicKey) { result in
switch result {
case .success(let nft):
...
case .failure:
...
}
}
The returned Nft object. This nft will not contain json data. It will only contain on-chain data. If you need access to the JSON offchain Metadata you can call. This call requires the metaplex object.
nft.metadata(metaplex: self.metaplex) { result in
switch result {
case .success(let metadata):
...
case .failure:
...
}
}
Similarly, the MasterEditionAccount account of the NFT will also be already loaded and, if it exists on that NFT, you can use it like so.
let masterEdition = nft.masterEditionAccount
Depending on the MasterEditionAccount version it can return v1 or v2 enums.
You can read more about the NFT model below.
The findAllByMintList method accepts an array of mint addresses and returns an array of Nfts. However, nil values will be returned for each provided mint address that is not associated with an NFT.
let nft = metaplex.nft.findAllByMintList(mintKeys: [mintPublicKey, mintPublicKey]) { result in
switch result {
case .success(let nfts):
// You can use nftList.compactMap{ $0 } to remove nils
...
case .failure:
...
}
}
NFTs retrieved via findAllByMintList will not have their JSON metadata loaded because this would require one request per NFT and could be inefficient if you provide a long list of mint addresses. Additionally, you might want to fetch these on-demand, as the NFTs are being displayed on your web app for instance.
Thus, if you want to load the JSON metadata of an NFT, you may do this like so.
nft.metadata(metaplex: self.metaplex) { result in
switch result {
case .success(let metadata):
...
case .failure:
...
}
}
We'll talk more about these tasks when documenting the NFT model.
The findAllByOwner method accepts a public key and returns all Nfts owned by that owner public key.
metaplex.nft.findAllByOwner(publicKey: ownerPublicKey) { [weak self] result in
switch result {
case .success(let nftList):
...
case .failure:
...
}
}
Similarly to findAllByMintList, the returned Nfts will not have their JSON metadata. This method is used on the Sample App.
The createNft method accepts an input and returns the Nft minted from the input. When creating the input, createNftInput requires a uri. This is where the off-chain json lives and can be a personal storage, aws, arweave, nftstorage, etc. You will need to have this uri before minting your Nft with createNft.
You may mint the Nft with a new or existing Account. If you are generating a new account for the mint you use AccountState.new(mintAccount) or you can use an existing account AccountState.existing(existingMintAccount). This tells the program whether or not to create and initialize a mint account or not.
metaplex.nft.createNft(input: createNftInput) { result in
switch result {
case .success(let nft):
case .failure:
}
}
Currently collections and verifying creators are not supported, but will be added in a future release.
Nft modelAll of the methods above either return or interact with an Nft object. The Nft object is a read-only data representation of your NFT that contains all the information you need at the top level.
You can see its full data representation by checking the code but here is an overview of the properties that are available on the Nft object.
// Always loaded.
public let metadataAccount: MetadataAccount
public let updateAuthority: PublicKey
public let mint: PublicKey
public let name: String
public let symbol: String
public let uri: String
public let sellerFeeBasisPoints: UInt16
public let creators: [MetaplexCreator]
public let primarySaleHappened: Bool
public let isMutable: Bool
public let editionNonce: UInt8?
// Sometimes loaded.
public let masterEditionAccount: MasterEditionAccount?
As you can see, some of the properties are loaded on demand. This is because they are not always needed and/or can be expensive to load.
In order to load these properties, you may run the metadata properties of the Nft object.
nft.metadata(metaplex: self.metaplex) { result in
switch result {
case .success(let metadata):
...
case .failure:
...
}
}
The Auction House module can be accessed via Metaplex.auctionHouse and provide the following methods. This is still a WIP and we are continuously adding more tests and documentation. These methods belong to the AuctionHouseClient class. AuctionHouseClient is separated into four sections currently. AuctionHouse, Bid, Listing, and Sale. You can find more information about them below.
create(input, callback)findByAddress(address, callback)findByCreatorAndMint(creator, treasuryMint, callback)All the methods return a callback. It's also possible to wrap them inside either RX, an async Result or Combine. We only provide this interface since it's the most compatible without forcing any specific framework.
The create method accepts properties that fills CreateAuctionHouseInput where sellerFeeBasisPoints is required to share part of the sale with the Auction House. Upon successful creation you will get an Auctionhouse object back.
public func create(
sellerFeeBasisPoints: UInt16,
requiresSignOff: Bool = false,
canChangeSalePrice: Bool = false,
auctioneerScopes: [AuthorityScope] = [],
treasuryMint: PublicKey = PublicKey(string: "So11111111111111111111111111111111111111112")!,
payer: Account? = nil,
authority: Account? = nil,
feeWithdrawalDestination: Account? = nil,
treasuryWithdrawalDestinationOwner: PublicKey? = nil,
auctioneerAuthority: PublicKey? = nil,
onComplete: @escaping (Result<Auctionhouse, OperationError>) -> Void
) { ... }
The findByAddress method accepts an address public key and returns an Auctionhouse object.
let address = PublicKey(string: "5xN42RZCk7wA4GjQU2VVDhda8LBL8fAnrKZK921sybLF")!
metaplex.auctionHouse.findByAddress(address) { result in
switch result {
case .success(let auctionHouse):
...
case .failure:
...
}
}
The findByCreatorAndMint method accepts a creator public key and treasurymint public key. It'll use these keys to derive a PDA and returns an Auctionhouse object.
let creator = PublicKey(string: "95emj1a33Ei7B6ciu7gbPm7zRMRpFGs86g5nK5NiSdEK")!
let treasuryMint = PublicKey(string: "So11111111111111111111111111111111111111112")!
metaplex.auctionHouse.findByCreatorAndMint(creator, and: treasuryMint) { result in
switch result {
case .success(let auctionHouse):
...
case .failure:
...
}
}
The returned Auctionhouse object will contain details about the Auction House account on chain.
The Auctionhouse object is a read-only data representation of the on chain Auction House and contains all the information you need at a top level. This model is generated by solita-swift and is found in the metaplex-swift-program-library.
public let auctionHouseDiscriminator: [UInt8] /* Auctionhouse.auctionHouseDiscriminator */
public let auctionHouseFeeAccount: PublicKey
public let auctionHouseTreasury: PublicKey
public let treasuryWithdrawalDestination: PublicKey
public let feeWithdrawalDestination: PublicKey
public let treasuryMint: PublicKey
public let authority: PublicKey
public let creator: PublicKey
public let bump: UInt8
public let treasuryBump: UInt8
public let feePayerBump: UInt8
public let sellerFeeBasisPoints: UInt16
public let requiresSignOff: Bool
public let canChangeSalePrice: Bool
public let escrowPaymentBump: UInt8
public let hasAuctioneer: Bool
public let auctioneerAddress: PublicKey /* `PublicKey.default` if `hasAuctioneer` is false */
public let scopes: [Bool] /* size: 7 */
Bidding is a part of the AuctionHouseClient and allows you to create, find, and cancel bids using the following methods:
bid(input, callback)findBidByReceipt(address, auctionHouse, callback)findBidByTradeState(address, auctionHouse, callback)findBidsBy(type, auctionHouse, callback)loadBid(bid, callback)cancelBid(auctioneerAuthority, auctionHouse, bid, callback)The bid method takes in parameters in order to fill the CreateBidInput struct in order to create a Bid on Auction House. The only required parameter is the AuctionhouseArgs, which are the properties that make up an Auctionhouse object. With all of the parameters set to their default you will have a basic Bid that uses the identity of the IdentityDriver.
public func bid(
auctionHouse: AuctionhouseArgs,
buyer: Account? = nil,
authority: Account? = nil,
auctioneerAuthority: Account? = nil,
mintAccount: PublicKey,
seller: PublicKey? = nil,
tokenAccount: PublicKey? = nil,
price: UInt64? = 0,
tokens: UInt64? = 1,
printReceipt: Bool = true,
bookkeeper: Account? = nil,
onComplete: @escaping (Result<Bid, OperationError>) -> Void
) { ... }
The findBidByReceipt takes a PublicKey address and an Auction House, using AuctionhouseArgs in order to find the bid on the Auction House. In your app you could create an Auctionhouse using create(input, callback) or find an auction house with findByAddress(address, callback) or findByCreatorAndMint(creator, treasuryMint, callback).
public func findBidByReceipt(
_ address: PublicKey,
auctionHouse: AuctionhouseArgs,
onComplete: @escaping (Result<Bid, OperationError>) -> Void
) { ... }
The findBidByTradeState is identical to findBidByReceipt except now you are using the trade state PublicKey to find the bid on the AuctionhouseArgs passed in.
public func findBidByTradeState(
_ address: PublicKey,
auctionHouse: Auctionhouse,
onComplete: @escaping (Result<Bid, OperationError>) -> Void
) { ... }
findBidsBy uses BidPublicKeyType to find multiple bids on the Auction House you provide using AuctionhouseArgs. The supported types are buyer, metadata, and mint.
enum BidPublicKeyType {
case buyer(PublicKey)
case metadata(PublicKey)
case mint(PublicKey)
}
public func findBidsBy(
type: BidPublicKeyType,
auctionHouse: AuctionhouseArgs,
onComplete: @escaping (Result<[Bidreceipt], OperationError>) -> Void
) { ... }
Use loadBid to finish loading the LazyBid with an asset, NFT, for a particular bid on the Auction House.
public func loadBid(_ bid: LazyBid, onComplete: @escaping (Result<Bid, OperationError>) -> Void) { ... }
Cancel a bid on the Auction House using cancelBid. A Bid object is required and you cannot use a LazyBid.
public func cancelBid(
auctioneerAuthority: Account? = nil,
auctionHouse: AuctionhouseArgs,
bid: Bid,
onComplete: @escaping (Result<SignatureStatus, OperationError>) -> Void
) { ... }
Bid is an object that consists of a LazyBid and an NFT. Sometimes you will only have LazyBid or a Bidreceipt. You can create a Bid object from these using the loadBid(bid, callback) method. A LazyBid can be created using an Auctionhouse and Bidreceipt to be passed into loadBid(bid, callback).
public struct Bid {
public let bidReceipt: LazyBid
public let nft: NFT
}
LazyBid is a partially loaded Bid. It's created from a BidReceipt and can be passed to loadBid(bid, callback) to fetch the asset in order to have access to the full Bid object.
public struct LazyBid {
public let auctionHouse: AuctionhouseArgs
public let tradeState: Pda
public let bookkeeper: PublicKey?
public let buyer: PublicKey
public let metadata: PublicKey
public let tokenAddress: PublicKey?
public let receipt: Pda?
public let purchaseReceipt: PublicKey?
public let price: UInt64
public let tokenSize: UInt64
public let createdAt: Int64
public let canceledAt: Int64?
}
Bidreceipt is the low-level data that the Auction House program uses to return raw Bid data. Since we are working with raw data here we don't have access to the NFT and has to be loaded using the loadBid(bid, callback) method to create a usable higher level Bid object.
public struct Bidreceipt: BidreceiptArgs {
public static let bidReceiptDiscriminator = [97, 99, 99, 111, 117, 110, 116, 58] as [UInt8]
public let bidReceiptDiscriminator: [UInt8]

public let price: UInt64
public let tokenSize: UInt64
public let bump: UInt8
public let tradeStateBump: UInt8
public let createdAt: Int64
public let canceledAt: COption<Int64>
}
Listing is a part of the AuctionHouseClient and allows you to list, find, and cancel listings using the following methods:
list(input, callback)findListingByReceipt(address, auctionHouse, callback)loadListing(listing, callback)cancelListing(auctioneerAuthority, auctionHouse, listing, callback)The list method takes in parameters in order to fill the CreateListingInput struct in order to create a Listing on Auction House. The required parameters are the AuctionhouseArgs and a UInt64 representing the price you want to charge. With all of the parameters set to their default you will have a basic Listing that uses the identity of the IdentityDriver.
public func list(
auctionHouse: AuctionhouseArgs,
seller: Account? = nil,
authority: Account? = nil,
auctioneerAuthority: Account? = nil,
mintAccount: PublicKey,
tokenAccount: PublicKey? = nil,
price: UInt64,
tokens: UInt64 = 1,
printReceipt: Bool = true,
bookkeeper: Account? = nil,
onComplete: @escaping (Result<Listing, OperationError>) -> Void
) { ... }
The findListingByReceipt takes a PublicKey address and an Auction House, using AuctionhouseArgs in order to find the listing on the Auction House. In your app you could create an Auctionhouse using create(input, callback) or find an auction house with findByAddress(address, callback) or findByCreatorAndMint(creator, treasuryMint, callback).
public func findListingByReceipt(
_ address: PublicKey,
auctionHouse: AuctionhouseArgs,
onComplete: @escaping (Result<Listing, OperationError>) -> Void
) { ... }
Use loadListing to finish loading the LazyListing with an asset, NFT, for a particular listing on the Auction House.
public func loadListing(_ listing: LazyListing, onComplete: @escaping (Result<Listing, OperationError>) -> Void) { ... }
Cancel a listing on the Auction House using cancelListing. A Listing object is required and you cannot use a LazyListing.
public func cancelListing(
auctioneerAuthority: Account? = nil,
auctionHouse: Auctionhouse,
listing: Listing,
onComplete: @escaping (Result<SignatureStatus, OperationError>) -> Void
) { ... }
Listing is an object that consists of a LazyListing and an NFT. Sometimes you will only have LazyListing or a Listingreceipt. You can create a Listing object from these using the loadListing(listing, callback) method. A LazyListing can be created using an Auctionhouse and Listingreceipt to be passed into loadListing(listing, callback).
public struct Listing {
public let listingReceipt: LazyListing
public let nft: NFT
}
LazyListing is a partially loaded Listing. It's created from a ListingReceipt and can be passed to loadListing(listing, callback) to fetch the asset in order to have access to the full Listing object.

public let receipt: Pda?
public let purchaseReceipt: PublicKey?
public let price: UInt64
public let tokenSize: UInt64
public let createdAt: Int64
public let canceledAt: Int64?
}
Bidreceipt is the low-level data that the Auction House program uses to return raw Bid data. Since we are working with raw data here we don't have access to the NFT and has to be loaded using the loadBid(bid, callback) method to create a usable higher level Bid object.
public struct Listingreceipt: ListingreceiptArgs {

}
Listing is a part of the AuctionHouseClient and allows you to list, find, and cancel listings using the following methods:
executeSale(input, callback)findPurchaseByReceipt(address, auctionHouse, callback)loadPurchase(purchase, callback)The executeSale method takes in parameters in order to fill the ExecuteSaleInput struct in order to execute the Purchase on the Auction House. The required parameters are the AuctionhouseArgs, along with the Bid, and Listing required for the sale. With the remaining parameters set to their default you will execute the sale using the identity of the IdentityDriver.
public func executeSale(
bid: Bid,
listing: Listing,
auctionHouse: AuctionhouseArgs,
auctioneerAuthority: Account? = nil,
bookkeeper: Account? = nil,
printReceipt: Bool = true,
onComplete: @escaping (Result<Purchase, OperationError>) -> Void
) { ... }
The findPurchaseByReceipt takes a PublicKey address and an Auction House, using AuctionhouseArgs in order to find the purchase on the Auction House. In your app you could create an Auctionhouse using create(input, callback) or find an auction house with findByAddress(address, callback) or findByCreatorAndMint(creator, treasuryMint, callback).
public func findPurchaseByReceipt(
_ address: PublicKey,
auctionHouse: AuctionhouseArgs,
onComplete: @escaping (Result<Purchase, OperationError>) -> Void
) { ... }
Use loadPurchase to finish loading the LazyPurchase with an asset, NFT, for a particular listing on the Auction House.
public func loadPurchase(_ purchase: LazyPurchase, onComplete: @escaping (Result<Purchase, OperationError>) -> Void) { ... }
Purchase is an object that consists of a LazyPurchase and an NFT. Sometimes you will only have LazyPurchase or a Purchasereceipt. You can create a Purchase object from these using the loadPurchase(purchase, callback) method. A LazyPurchase can be created using an Auctionhouse and Purchasereceipt to be passed into loadPurchase(purchase, callback).
public struct Purchase {
public let purchaseReceipt: LazyPurchase
public let nft: NFT
}
LazyPurchase is a partially loaded Purchase. It's created from a Purchasereceipt and can be passed to loadPurchase(purchase, callback) to fetch the asset in order to have access to the full Purchase object.

You can read more about Auction House in our online docs.
The Candy Machine module can be accessed via Metaplex.candyMachine and provides the following methods. This is still a WIP and we are continuously adding more tests and documentation. These methods belong to the CandyMachineClient class. You can find more information below.
All the methods return a callback. It's also possible to wrap them inside either RX, an async Result or Combine. We only provide this interface since it's the most compatible without forcing any specific framework.
The create method accepts properties that fills CreateCandyMachineInput where price, sellerFeeBasisPoints, and itemsAvailable are required. Upon successful creation you will get a CandyMachine object back.
public func create(
candyMachine: Account = HotAccount()!,
wallet: Account? = nil,
payer: Account? = nil,
authority: Account? = nil,
collection: PublicKey? = nil,
tokenMint: PublicKey? = nil,
price: UInt64,
sellerFeeBasisPoints: UInt16,
itemsAvailable: UInt64,
symbol: String = "",
maxEditionSupply: UInt64 = 0,
isMutable: Bool = true,
retainAuthority: Bool = true,
goLiveDate: Int64? = nil,
endSettings: EndSettings? = nil,
hiddenSettings: HiddenSettings? = nil,
whitelistMintSettings: WhitelistMintSettings? = nil,
gatekeeper: GatekeeperConfig? = nil,
creatorState: CreatorState? = nil,
onComplete: @escaping (Result<CandyMachine, OperationError>) -> Void
) { ... }
The mint method accepts properties that fills MintCandyMachineInput where a CandyMachine is required. A CandyMachine should first be created on-chain and passed to the mint method. Upon successful creation you will get a NFT object back.
public func create(
candyMachine: CandyMachine,
payer: Account? = nil,
newMint: Account = HotAccount()!,
newOwner: PublicKey? = nil,
newToken: PublicKey? = nil,
payerToken: PublicKey? = nil,
whitelistToken: PublicKey? = nil,
onComplete: @escaping (Result<NFT, OperationError>) -> Void
) { ... }
The findByAddress method accepts an address public key and returns a CandyMachine object.
let address = PublicKey(string: "5xN42RZCk7wA4GjQU2VVDhda8LBL8fAnrKZK921sybLF")!
metaplex.candyMachine.findByAddress(address) { result in
switch result {
case .success(let candyMachine):
...
case .failure:
...
}
}
CandyMachine is a wrapper around the auto-generated Candymachine object. CandyMachine also gives us easy access to the CandyMachine address. CandyMachine has convenient getters to access properties of Candymachine.
public struct CandyMachine {
private let candyMachine: Candymachine
let address: PublicKey
public init(
candyMachine: Candymachine,
address: PublicKey
) {
self.candyMachine = candyMachine
self.address = address
}
public var authority: PublicKey { candyMachine.authority }
public var wallet: PublicKey { candyMachine.wallet }
public var tokenMint: PublicKey? { candyMachine.tokenMint }
public var collectionMint: PublicKey? { nil }
public var price: UInt64 { candyMachine.data.price }
public var symbol: String { candyMachine.data.symbol }
public var sellerFeeBasisPoints: UInt16 { candyMachine.data.sellerFeeBasisPoints }
public var isMutable: Bool { candyMachine.data.isMutable }
public var retainAuthority: Bool { candyMachine.data.retainAuthority }
public var goLiveDate: Int64? { candyMachine.data.goLiveDate }
public var maxEditionSupply: UInt64 { candyMachine.data.maxSupply }
public var itemsAvailable: UInt64 { candyMachine.data.itemsAvailable }
public var endSettings: EndSettings? { candyMachine.data.endSettings }
public var hiddenSettings: HiddenSettings? { candyMachine.data.hiddenSettings }
public var whitelistMintSettings: WhitelistMintSettings? { candyMachine.data.whitelistMintSettings }
public var gatekeeper: GatekeeperConfig? { candyMachine.data.gatekeeper }
public var creators: [Creator] { candyMachine.data.creators }
}
The current identity of a Metaplex instance can be accessed via metaplex.identity() and provide information on the wallet we are acting on behalf of when interacting with the SDK.
This method returns an identity object with the following interface. All the methods required a solana api instance
public protocol IdentityDriver {
var publicKey: PublicKey { get }
func sendTransaction(serializedTransaction: String, onComplete: @escaping(Result<TransactionID, IdentityDriverError>) -> Void)
func signTransaction(transaction: Transaction, onComplete: @escaping (Result<Transaction, IdentityDriverError>) -> Void)
func signAllTransactions(transactions: [Transaction], onComplete: @escaping (Result<[Transaction?], IdentityDriverError>) -> Void)
}
The implementation of these methods depends on the concrete identity driver being used. For example use a KeypairIdentity or a Guest(no publickey added)
Let’s have a quick look at the concrete identity drivers available to us.
The GuestIdentityDriver driver is the simplest identity driver. It is essentially a null driver that can be useful when we don’t need to send any signed transactions. It will return failure if you use signTransaction methods.
The KeypairIdentityDriver driver accepts an Account object as a parameter.
The KeypairIdentityDriver driver accepts a PublicKey object as a parameter. It's a read only similar to the GUestIdentity but it has the provided PublicKey. It will return failure if you use signTransaction methods.
You may access the current storage driver using metaplex.storage() which will give you access to the following interface.
public protocol StorageDriver {
func download(url: URL, onComplete: @escaping(Result<NetworkingResponse, StorageDriverError>) -> Void)
}
Curently it's only used to retrieve json data off-chain.
This will use URLShared networking. Which is the default iOS networking implementation. This may be the most useful call.
This will use return Empty Data object with 0 size.
Currently tests are a mix between devnet, mainnet, and locally using amman. We are in the process of getting amman working on CI in order to move all tests to the local validator.
All Auction House tests are set to run locally using amman, but are commented out so CI can pass. To run these tests you will need the js sdk. With the repo cloned, from the terminal run the following commands from the js directory:
yarn install
yarn amman:start
As mentioned above, this SDK is still in very early stages. We plan to add a lot more features to it. Here’s a quick overview of what we plan to work on next.
The SDK heavily inspired in the JS-Next. The objective of this is to have one Metaplex wide interface for all NFTs. If you use the Js-Next sdk this sdk should be familiar.
