I've defined a custom layer property (used by a custom subclass of UIView) that I animate with a UIView.animated (or UIView.animateKeyframes). I have some strange crashes arround the property.
: -[__NSCFType doubleValue]: unrecognized selector sent to instance
Note that when used on a small sample project the animation/view never crash but crash in my main project. Any advice of what I should check? Xcode project settings seems the same. Something else in code or configuration to check?
