`*-apple-visionos`

Apple visionOS / xrOS targets.

Tier: 3

aarch64-apple-visionos: Apple visionOS on arm64.
aarch64-apple-visionos-sim: Apple visionOS Simulator on arm64.

Requirements

These targets are cross-compiled, and require the corresponding visionOS SDK (XROS.sdk or XRSimulator.sdk), as provided by Xcode 15 or newer.

The path to the SDK can be passed to rustc using the common SDKROOT environment variable.

OS version

The minimum supported version is visionOS 1.0.

This can be raised per-binary by changing the deployment target. rustc respects the common environment variables used by Xcode to do so, in this case XROS_DEPLOYMENT_TARGET.

Building the target

The targets can be built by enabling them for a rustc build in config.toml, by adding, for example:

[build]
target = ["aarch64-apple-visionos", "aarch64-apple-visionos-sim"]

Using the unstable -Zbuild-std with a nightly Cargo may also work.

Note: Currently, a newer version of libc and cc may be required, this will be fixed in #124560.

Building Rust programs

Rust programs can be built for these targets by specifying --target, if rustc has been built with support for them. For example:

$ rustc --target aarch64-apple-visionos-sim your-code.rs

There is no support for running the Rust or standard library testsuite at the moment. Testing has mostly been done manually with builds of static libraries embedded into applications called from Xcode or a simulator.

It hopefully will be possible to improve this in the future.

Cross-compilation toolchains and C code

The Clang target is suffixed with -xros for historical reasons.

LLVM 18 or newer is required to build this target.
