Hi Ma’am!  
Thanks for the great course like this. How we get the keyPath/key names and you use animation name “stroke”, so how to know those values generally to use in KVO functionalities.

Thanks

@abnboys - I don’t know of a single apple documentation reference for these. In the documentation, properties are marked with **Animatable**.

For example: [Apple Developer Documentation](https://developer.apple.com/documentation/quartzcore/cashapelayer) - scroll down to `fillColor`. It’s marked Animatable in the description.

In the archived documentation there’s the CALayer properties: [Animatable Properties](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/CoreAnimation_guide/AnimatableProperties/AnimatableProperties.html#//apple_ref/doc/uid/TP40004514-CH11-SW1)  
but these don’t include CAShapeLayer properties.

Some kind person has put up a useful list on stackoverflow: [core animation - What is the full Keypath list for CABasicAnimation? - Stack Overflow](https://stackoverflow.com/a/49480213)
