AsyncObjC

Example Project for Calling Objective-C APIs Asynchronously.

Overview

Method written Objective-C having specific format completion is automatically converted asynchronous functions in Swift.

1. The method has a void return type.
2. The block has a void return type.
3. The block is called exactly once, on all possible paths of control flow.

For example,

- (void)handleVoidWithCompletion:(void (^)(void))completion;

can be called as below in Swift.

await objc.handleVoid()
