Wait for some completion in main thread using Catalyst environment
I need to bring an iOS application to macOS using Catalyst. This application contain parts where it waits for a button to be pressed in the main thread, using [[NSRunLoop mainRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.1]]; in a while loop to allow some dispatching while waiting. I know that this is not good style, but I need to convert this old source code and mentioned that when using this part of code under Catalyst, the main thread will not dispatch. So the button cannot be clicked, and a beach ball appears after two seconds. I saw a similar construct for native macOS applications: NSEvent *event= [[NSApplication sharedApplication] nextEventMatchingMask:NSEventMaskAny untilDate:[NSDate dateWithTimeIntervalSinceNow:0.1] inMode:NSDefaultRunLoopMode dequeue:YES]; if (event) { [[NSApplication sharedApplication] sendEvent:event]; } but I do not have access to NSEvent and NSApplication in a Catalyst environment. Question: I there any code snippet which I can use to achieve the above? I do not want to completely rewrite old code if there is a solution for this. Any ideas or hints are highly appreciated. Thank you! Markus
