NSSplitView - how to programmatically hide or collapse a subview of a split view
// if it's a horizontal divider...
[_splitView setPosition:_splitView.bounds.size.height ofDividerAtIndex:0];

Call "waitForCompletion" after invoking an async method. Upon receiving notification, set "executionDate" to YES and call [runloopExpirationTimer fire]. This will "dry up" the fake run loop.
- (void)waitForCompletion {
runloopExpirationTimer = [NSTimer scheduledTimerWithTimeInterval:600.0 target:self selector:@selector(dumbTimerMethod:) userInfo:nil repeats:NO];
while ( !executionDone ) {
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
}
}
- (void)dumbTimerMethod:(NSTimer *)theTimer {
runloopExpirationTimer = nil;
}

Mac/iOS - Checks whether a file URL is a document package, regular or a folder.
// Assume base path is your Desktop
