Hi, I’m trying to understand how to use the GKTurnBasedMatch facility in Game Kit. From reading the documentation, I’m not quite sure how make it work with the rules of the game I am developing.

I should have probably said - “it actually doesn’t matter if its run on the Main thread or not, since the delegate its calling is thread safe”. The class that the delegate calls to update the UI

My understanding is that an optional is just a type that wraps another type. So you need to unwrap the optional before calling String(describing: type(of: value))) to get the class name that you are

How to translate this into Swift - (id)transformedValue:(id)value { if ( ![value respondsToSelector: @selector(doubleValue) ] ) { NSLog(@"%s Error value %@ %@",__FUNCTION__, [value class],

It’s not clear which part of that is giving you trouble, but I was able to do this in a playground (Swift 4, Xcode 9), and got the expected output: Note that Swift’s “AnyObject” has the same
