Hello Caroline,
I get a new MacBook Pro (M1) to run the chapter 20 AdvancedLighting source code, but I receive this error:
Execution was interrupted, reason: EXC_BREAKPOINT (code=1, subcode=0x1a6b35d78).
The process has been left at the point where it was interrupted, use “thread return -x” to return to the state before expression evaluation.
Hi there
If this is in the playground, it’s to do with Apple changing the way the library is created.
In Renderer.swift, change:
guard let path = Bundle.main.path(forResource: "Shaders", ofType: "metal") else { fatalError() }
let input = try String(contentsOfFile: path, encoding: String.Encoding.utf8)
let library = try device.makeLibrary(source: input, options: nil)
To:
let library = device.makeDefaultLibrary()!
and it should work. My M1 does
You’ll need to change Renderer.swift for the playground pages 1. reflection, 2. refraction and 3. water.
