Swift MacOS NSAnimationContext not following its duration

Question

I have a very simple animation which is moving a view throughout the main view like this:

NSAnimationContext.runAnimationGroup({ (_) in
    NSAnimationContext.current.duration = 50.0
    viewTOModify.frame.origin.x = -20
}) {
    print("finished")
}

This issue I have with this is that the movement is instantaneous and there is not the duration I set. Thanks for the help in advanced.

Answer 1

You can use the view's .animator() method like this:

NSAnimationContext.runAnimationGroup({ (_) in
    NSAnimationContext.current.duration = 50.0
    viewTOModify.animator().frame.origin.x = -20
}) {
    print("finished")
}

If you don't want to use .animator() you have to set .allowsImplicitAnimation like this:

NSAnimationContext.runAnimationGroup({ (_) in
    NSAnimationContext.current.duration = 50.0
    NSAnimationContext.current.allowsImplicitAnimation = true
    viewTOModify.frame.origin.x = -20
}) {
    print("finished")
}
