Could you provide the backtrace as mentioned in the error message? i.e.: RUST_BACKTRACE=1 && cargo run --bin quad --features metal

Also, which version of macOS are you running?

Thanks! Is that the backtrace you get when running the example with RUST_BACKTRACE=1? Or is there somewhere else that shows the full Rust callstack which ends in

thread 'main' panicked at 'called Option::unwrap() on a None value', libcore/option.rs:335:21
note: Run with RUST_BACKTRACE=1 for a backtrace.

?

I thought it would be in that backtrace. I'm trying to see which selector is failing – maybe we are accidentally using a feature that was added in Metal 2, since the quad example runs fine on my Macbook (on 10.13.4).

Ok great, this is helpful. Thanks!

It looks like it's simply the buffers selector which fails here: https://github.com/gfx-rs/gfx/blob/master/src/backend/metal/src/internal.rs#L241 because it's only supported on macOS 10.13+/iOS 11.0+/tvOS 11.0+.

So it seems like we should just avoid this optimization for older macOS/iOS/tvOS, unless there is another way to set mutability (cc @kvark and #1999)

It seems like we can reliably feature detect this case (and other selectors) with the following:

MTLComputePipelineDescriptor *desc = [MTLComputePipelineDescriptor new];
BOOL supportsBuffers = [desc respondsToSelector:@selector(buffers)];

This is preferable to version checking IMO. I don't know how this fits into our Metal bindings though. Maybe we simply have fn supports_xyz() -> bool for these situations so we can cache the feature detection (to avoid performing this check directly in all getters/setters), or some lazy static approach that returns some Err
