Issue running Scene Kit's presentation WWDC2013 code

I am trying to run the source code from Apple's Scene Kit presentation from WWDC2013. I am getting an error and not sure how to resolve.

Here is the error I am getting:

ASCSlideNodeDelegate.m:238:94: Type of property 'view' ('NSView * _Nonnull') does not match type of accessor 'view' ('SCNView *')

Any assistance would be greatly appreciated!

Solution

  • The definition of the SCNView in ASCPresentationViewController needs to be changed to match new SDK headers.

    In the ASCPresentationViewController.h, switch from a method declaration for the -view superclass override to a property in the header, and specify @dynamic for that property in ASCPresentationViewController.m.

    @property (strong) SCNView *view;
//- (SCNView *)view;

@dynamic view;
//- (SCNView *)view {
//    return (SCNView *)[super view];
//}

    You can find diffs for some other needed updates at Updating SceneKit WWDC 2013 slides for Xcode 7 (my Wordpress blog).
