I have a set up like so:

But I repeatably/consistently get crashes on this line, using my iPhone 6 Plus and 6s Plus simulator:
https://github.com/MrMatthias/SwiftColorPicker/blob/2fdaf66f186e868f66a4cf751d10923e69960e0b/Source/PickerImage.swift#L76

Something weird happening to the CFMutableDataRef? Size not expected?
It's worth nothing I took that screenshot of the UI in the crashed state.
