What you did

I cloned the bevy repo and I ran make run in the correct directory as described in https://github.com/bevyengine/bevy/tree/main/examples#build--run-1

What went wrong

The build failed.

Additional information

build.log (gist)

Let me know if you have any further questions, as I don't know what else to say.

There is an issue currently in the Rust ecosystem where target triples are changing for the simulator. In Apple Clang version 17, the target triple changed from arm64-apple-ios-sim to arm64-apple-ios-simulator.

This is being fixed everywhere starting with rust-lang/rust-bindgen#3182, but it needs to be done everywhere.

For now we're blocked on this in Bevy. If you build for real devices it should work

made this required bindgen-release an explicit issue: rust-lang/rust-bindgen#3199
