Swift API client for Uploadcare

license swift Build Status

Uploadcare Swift API client for iOS, iPadOS, tvOS, macOS, and Linux handles uploads and further operations with files by wrapping Uploadcare Upload and REST APIs.

Check out our Demo App.

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:

final class MyClass {
    private var uploadcare: Uploadcare
    
    init() {
        self.uploadcare = Uploadcare(withPublicKey: "YOUR_PUBLIC_KEY")
        
        // Secret key is optional if you want to use Upload API only.
        // REST API requires both public and secret keys:
        self.uploadcare = Uploadcare(withPublicKey: "YOUR_PUBLIC_KEY", secretKey: "YOUR_SECRET_KEY")
    }
}

You can create more Uploadcare objects if you need to work with multiple projects in your Uploadcare account:

final class MyClass {
    private let project1: Uploadcare
    private let project2: Uploadcare
    
    init() {
        // A project to use Upload API only 
        self.project1 = Uploadcare(withPublicKey: "YOUR_PUBLIC_KEY_1")

        // A project to use both REST API and Upload API
        self.project2 = Uploadcare(withPublicKey: "YOUR_PUBLIC_KEY_2", secretKey: "YOUR_SECRET_KEY_2")
    }
}

Keep in mind that since Uploadcare is not a singleton. You should store a strong reference (as an instance variable, for example) to your Uploadcare object or it will get deallocated.

Using Upload API

Check the Upload API documentation to see all available methods.

Example of 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.file(fromData: data)
let fileForUploading2 = uploadcare.file(withContentsOf: url)

// Handle error or result
fileForUploading1.upload(withName: "random_file_name.jpg", store: .store) { result 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.uploadFile(data, withName: "random_file_name.jpg", store: .store) { progress in
    print("upload progress: \(progress * 100)%")
} _: { result in
    switch result {
    case .failure(let error):
        print(error.detail)
    case .success(let file):
        print(file)
    }
}
// You can cancel uploading if needed
task.cancel()

// task will confirm UploadTaskable protocol if file size is less than 100 mb, and UploadTaskResumable if file size is >= 100mb
// You can pause or resume uploading of file with size >= 100mb if needed
(task as? UploadTaskResumable)?.pause()
(task as? UploadTaskResumable)?.resume()

It is possible to perform uploads in background. But implementation is a platform-specific. This lib doesn't provide default implementation. You can find an example for the iOS in our Demo app. See FilesListStore.swift.

Using REST API

Refer to the REST API documentation for all methods.

Example of getting list of files:

// Make a list of files object
lazy var filesList = uploadcare.listOfFiles()

func someFilesListMethod() {
    // Make a query object
    let query = PaginationQuery()
        .stored(true)
        .ordering(.sizeDESC)
        .limit(5)

    // Get file list
    filesList.get(withQuery: query) { result in
        switch result {
        case .failure(let error):
            print(error)
        case .success(let list):
            print(list)
        }
    }
}

Get next page:

// Check if the next page is available
guard filesList.next != nil else { return }
// Get the next page
filesList.nextPage { result in
    switch result {
    case .failure(let error):
        print(error)
    case .success(let list):
        print(list)
    }
}

Get previous page:

// Check if the previous page is available
guard filesList.previous != nil else { return }
// Get the previous page
filesList.previousPage { result in
    switch result {
    case .failure(let error):
        print(error)
    case .success(let list):
        print(list)
    }
}
