Class for logging excessive blocking on the main thread
Watchdog
Class for logging excessive blocking on the main thread. It watches the main thread and checks if it doesn’t get blocked for more than defined threshold.
? Main thread was blocked for 1.25s ?
You can also inspect which part of your code is blocking the main thread.
Usage
Simply, just instantiate Watchdog with number of seconds that must pass to consider the main thread blocked. Additionally you can enable strictMode that stops the execution whenever the threshold is reached. This way, you can inspect which part of your code is blocking the main thread.
let watchdog = Watchdog(threshold: 0.4, strictMode: true)
Don’t forget to retain Watchdog somewhere or it will get released when it goes out of scope.
