Feature Highlights

  • Compatible with iOS and macOS
  • No deadlocks
  • Support for callback based asynchronous code
  • Support for swift-concurrency based asynchronous code

Basic usage

Resyncer help you calling asynchronous code in a synchronous environment by suspending current thread execution, waiting for asynchronous work to complete. This is done by offloading asynchronous work to a different thread either by using an OperationQueue or by making use of swift-concurrency Task.

Because Resyncer is going to block the calling thread, make sure not to use it from the Main Thread.

Usage with callback based asynchronous code

If you have an asynchronous function that posts a value on a provided callback using swift Result (or also without Result, you can construct it yourself):

func asyncWork(_ completion: @escaping (Result<Int, Error>) -> Void) { ... }

You can use Resyncher to obtain the produced value in a synchronouse environment:

let x = try resyncer.synchronize { callback in
    self.asyncWork { result in
        callback(result)
    }
}

Usage with swift-concurrency based asynchronous code

If you have an asynchronous function that returns a value:

func asyncWork() async throws -> Int { ... }

You can use Resyncher to obtain the produced value in a synchronouse environment:

let x = try resyncer.synchronize { callback in
    try await self.asyncWork()
}

Installation

Cocoapods

Add the dependency to the Resyncer framework in your Podfile:

pod 'Resyncer', '~> 1.0.0'
