A note regarding "helper" classes for use as a layer's delegate (with ARC at least):

Make sure you store a "strong" reference to your alloc/init'd helper class (such as in a property).

If I assign the helper class to a property, then assign it to the delegate, my weird crashes go away, and things behave as expected.
