Installation

Swift Package Manager

To use a stable version, add a dependency to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/uploadcare/uploadcare-swift.git", .branch("master"))
]

If you want to try the current dev version, change dependency to:

dependencies: [
    .package(url: "https://github.com/uploadcare/uploadcare-swift.git", branch("develop"))
]

To add from Xcode select File -> Swift Packages -> Add Package Dependency and enter repository URL:

https://github.com/uploadcare/uploadcare-swift

Or you can add it in Xcode: https://github.com/uploadcare/uploadcare-swift (select master branch).

Carthage

To use a stable version, add a dependency to your Cartfile:

github "uploadcare/uploadcare-swift"

To use the current dev version:

github "uploadcare/uploadcare-swift" "develop"

Cocoapods

To use a stable version, add a dependency to your Podfile:

pod 'Uploadcare', git: 'https://github.com/uploadcare/uploadcare-swift'

To use current dev version:

pod 'Uploadcare', git: 'https://github.com/uploadcare/uploadcare-swift', :branch => 'develop'

Initialization

Create your project in Uploadcare dashboard and copy its API keys from there.

Upload API requires only a public key, while REST API requires both public and secret keys:

let uploadcare = Uploadcare(withPublicKey: "YOUR_PUBLIC_KEY")
// Secret key is optional. Initialization with secret key:
let uploadcare = Uploadcare(withPublicKey: "YOUR_PUBLIC_KEY", secretKey: "YOUR_SECRET_KEY")

Using Upload API

Check the Upload API documentation to see all available methods.

Example of direct uploads:

guard let url = URL(string: "https://source.unsplash.com/random") else { return }
guard let data = try? Data(contentsOf: url) else { return }

// You can create UploadedFile object to operate with it
let fileForUploading1 = uploadcare.uploadAPI.file(fromData: data)
let fileForUploading2 = uploadcare.uploadAPI.file(withContentsOf: url)

// Handle error or result
fileForUploading1.upload(withName: "random_file_name.jpg", store: .store) { (result, error) in
}

// Completion block is optional
fileForUploading2?.upload(withName: "my_file.jpg", store: .store)

// Or you can just upload data and provide a filename
let task = uploadcare.uploadAPI.upload(files: ["random_file_name.jpg": data], store: .store, expire: nil, { (progress) in
    print("upload progress: \(progress * 100)%")
}) { (resultDictionary, error) in
    if let error = error {
        print(error)
        return
    }

    guard let files = result else { return }			
    for file in files {
        print("uploaded file name: \(file.key) | file id: \(file.value)")
    }
}

// You can cancel uploading if needed
task.cancel()

Using REST API

Refer to the REST API documentation for all methods.

Example of getting list of files:

// Make a query object
let query = PaginationQuery()
    .stored(true)
    .ordering(.sizeDESC)
    .limit(5)
// Make a list of files object
let filesList = uploadcare.list()

// Get file list
filesList.get(withQuery: query) { (list, error) in
    if let error = error {
        print(error)
        return
    }
			
    print(list ?? "")
}

Get next page:

// Check if the next page is available
guard filesList.next != nil else { return }
// Get the next page
filesList.nextPage { (list, error) in
    if let error = error {
        print(error)
        return
    }	
    print(list ?? "")
}

Get previous page:

// Check if the previous page is available
guard filesList.previous != nil else { return }
// Get the previous page
filesList.previousPage { (list, error) in
    if let error = error {
        print(error)
        return
    }	
    print(list ?? "")
}
