I can see why you found this pattern tedious, Objective-C needs so much boilerplate to do something trivial:
if (!NSThread.isMainThread) {
[NSOperationQueue.mainQueue addOperationWithBlock:^{
[self setStreamHandler:handler completion:completion];
}];
return;
}
[self.channel setStreamHandler:handler];
completion();or
void (^block)(void) = ^{ // or typedef
[self.channel setStreamHandler:handler];
completion();
};
if (NSThread.isMainThread) {
block();
} else {
[NSOperationQueue.mainQueue addOperationWithBlock:block];
}I guess the utility function was better... 😞

What was the motivation to do this? I thought the existing code was cleaner?

Yep. This is used to verify if an operation is on capture session queue.
