Warren writing Swift! There were as many implicitly unwrapped optionals as I expected. 
Next installment needs some Unsafe* types.
New (!!) on Metal By Example: Writing a Modern Metal App from Scratch (Part 1) http://metalbyexample.com/modern-metal-1/ Same teapot, new language.

How do you avoid IUOs in your view controller interfaces? Genuine question
-
Definitely can't sometimes. I prefer initializing properties directly like `let mtlView = MTLView()` rather than have an IUO and init in viewDidLoad if possible.
-
Lazy properties are a great option too
Gives you the deferred loading you usually want in VCs, while still getting rid of "Non-optional optionals":
lazy var mltView = MTLView() -
I have, over the past four years, developed a rather nuanced opinion about this, I think. Obj-C is probably too lax about this. But Swift is definitely too strict about it, in ways that are distracting and detrimental.

Just finished porting all of
@unbound_io’s PlayEngine to OSX. Hit a wall with OpenGL 4.1. Even with the Nvidia Web Driver. Can you please do the Metal port for us Warren :-) -
Would love to help. Reach out to warren@fourspace.co. Though, don’t have access to Nvidia hardware or any eGPU for the rest of the month.

Let's chat when we're all back in SF.

Deal. I’ll be back 1 Sept. Or we can meet up at SIGGRAPH?
-
Not gonna make it to SIGGRAPH this year. Looking forward though!
