Apple iOS Simulator on ARM64.

Expand Down Expand Up @@ -39,17 +39,16 @@ Currently there is no support to run the rustc test suite for this target.

*Note: Building for this target requires the corresponding iOS SDK, as provided by Xcode 12+.*

If `rustc` has support for that target and the library artifacts are available,
then Rust programs can be built for that target:
From Rust Nightly 1.56.0 (2021-08-03) on the artifacts are shipped pre-compiled:

```text
rustc --target aarch64-apple-ios-sim your-code.rs
rustup target add aarch64-apple-ios-sim --toolchain nightly
```

On Rust Nightly it is possible to build without the target artifacts available:
Rust programs can be built for that target:

```text
cargo build -Z build-std --target aarch64-apple-ios-sim
rustc --target aarch64-apple-ios-sim your-code.rs
```

There is no easy way to run simple programs in the iOS simulator.
