Stop caring about retain count. Follow the memory management rules

This puzzles me a bit:
...
NSUInteger rc;
CALayer *layer = [CALayer layer];
rc = [layer retainCount];
// rc == 1 as expected
layer.frame = CGRectMake(...);
rc = [layer retainCount];
// now rc == 2, it's not clear to me why

Why does setting a frame on the layer increments its retain count?

Wait, Handle? NewHandleClear? Your use of these functions suggests that you may
be working from a dangerously old textbook. There's really no reason to use
them in new code._
Ah I understand, that makes sense. Thanks.

And indeed, your plist is broken. CFBundleDisplayName should be a string not
an array. It seems that what is "CFBundleDisplayName" should be
