AsynchronousOperation

Requirements

Installation

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

pod 'AsynchronousOperation'

Usage

AsynchronousOperation is a lightweight version of the sample code presented at the WWDC Advanced NSOperation session.

Its main purpose is to make it easier to create Operation wrapping asynchronous tasks such as a HTTP request.

Subclass AsynchronousOperation or directly instanciate a AsynchronousBlockOperation.

let operationQueue = OperationQueue()

let operation = AsynchronousBlockOperation(task: { completion in
    httpManager.fetch(User.self, using: request) { result in
        // ... Handle result
        completion()
    }
})

operationQueue.addOperation(operation)

// OR

class FetchUserOperation: AsynchronousOperation {

    override func execute() {
        httpManager.fetch(User.self, using: request) { [weak self] result in
            // ... Handle result
            self?.finish()
        }
    }
}

I mainly use it to chain multiple promises that are not initialized at the same time.
