Apple Game Frameworks and Technologies: Class not decoded '' (Ch. 16)

Has anyone else run into this error message? Class not decoded 'valsrevenge.HealthComponent'

I have seen this when trying to run the example finished in Ch. 16 provided by Tammy when trying to load GameScene_1 in the simulator, and also in my own project when trying to load any GameScene that is not GameScene_1

I have also noticed then in another project provided by Tammy with the PhysicsComponent

It looks like it can be solved with removing the custom components from the copied over scenes in your project. Then replace re-add them in the scene editor

This takes a while because you have to do this for the monsters and player nodes. If you don’t copy the .sks files over from the example project, it likely works fine
