Hi! Thanks for the report!

This warning can't be helped. It's printed by the system when performing the alpha fade animation on the UIVisualEffectView instance that creates the blurry effect outside the region of the crop box. While the warning itself says the effect will look broken, it looks absolutely fine to me. Unfortunately, since it's on the system level, it can't be suppressed.

However, I did a bit of research, and discovered there's actually now an official way to perform the animation in iOS 9, that creates a blurry animation effect similar to dragging down on the iOS Home Screen to open Spotlight (i.e., the blur radius expands instead of a static crossfade).

I've since modified the library to use this animation method on iOS 9, and the console warning has gone away. It will, however, still appear if the device in question is running iOS 8.

Thanks a lot for the help!

Thank you very much for your quickly fix :).

I've just tested it on Simulator from iOS version 7 to 9 and I can confirm that aforementioned warning no longer appears in either of the tested versions. I would have expected to appear in 7 and 8 after your words. But it doesn't. So maybe something else has been changed?. Anyway, I only mention to put it in your knowledgement.

Thank you again for your great work!

Haha no problems! Thanks for reporting it! I was going to ignore it forever!

Uh-oh. Really? It SHOULD still be happening in iOS 8. It won't happen in iOS 7 since UIVisualEffectView wasn't available then, so it's using a normal UIToolbar instead.

I might need to test that again... XD
