Subclassing a GBAsyncOperation

This is an example of a typical asynchronous operation subclass. For the proper operation lifecycle it is required to call finish() method upon async code completion. This will signal the operation that it should be finished, otherwise it will be stuck in the queue.

class MyAsyncOperation: GBAsyncOperation {

    // your properties
    
    var completion: () -> Void
    
    init(completion: @escaping () -> Void) {
        self.completion = completion 
    }

    override func main() {
        // your async code here, which eventually calls completeOperation()
    }

    func completeOperation() {
        guard !isCancelled else {
            return
        }
        
        completion()
        finish()
    }
}

Bundling operations using a GBSerialGroupOperation

GBSerialGroupOperation class provides an ability of grouping asynchronous operations in a bundle and creating a dependency between them
