TinkoffConcurrency requires Swift 5.5 and higher, with support of Swift Concurrency. This way, all Xcode versions starting from 13.0 would work. It's advisable to use Xcode at least 13.2.1 or higher, as it provides backward compatibility with iOS 13.0 and higher.



TinkoffConcurrency is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'TinkoffConcurrency'

Swift Package Manager

  1. From File menu, select Add Packages...

  2. Enter https://github.com/tinkoff-mobile-tech/TinkoffConcurrency into repository URL

  3. Select Up to Next Major Version, and use 1.2.0 as a minimum version

  4. Select your project in Add to Project and click Add Package

  5. In opened dialog, choose target to add library to


The documentation is available here:

Old versions


To run the example project, clone the repo, and run pod install from the Example directory first. Example app is a small demo that illustrates behavior of withCheckedThrowingCancellableContinuation for both cancellable and non-cancellable tasks, and compares that to vanilla withCheckedThrowingContinuation behavior.

Example application needs iOS 15.0 to run, as it uses new SwiftUI features. It does NOT imply any restrictions of using TinkoffConcurrency library on older iOS versions.
