Video Tutorial: iOS Animation with Swift Part 7: CAAnimationGroups

Update 12/23/14: Series updated for Xcode 6.1.1

Update: As a user on the forums has noticed the color tint animation does not kick in without specifying a “fromValue” for the tint animation. Just update tintBackgroundColor(…) to include: tint.fromValue = layer.backgroundColor.

Challenge
