The iOS toolchain can be built on Linux with minor changes. The compilation will invoke `xcrun` to find the path to the iPhone SDK but a fake `xcrun` executable can be used. ``` #!/bin/sh echo "/path/to/sdk" ``` The iOS toolchain can then be built and linked with rustup. ``` $ ./x.py build --stage 2 --host x86_64-unknown-linux-gnu \ --target aarch64-apple-ios $ rustup toolchain link stage1 build/x86_64-unknown-linux-gnu/stage1 ``` It's possible to take this toolchain and compile an iOS executable with it. This requires the ld64 linker and an iOS SDK. The ld64 linker can be taken from [cctools](https://github.com/tpoechtrager/cctools-port). A project's .cargo/config can then be edited to use the linker for this target. ``` [target.aarch64-apple-ios] linker = "/path/to/cctools/bin/arm-apple-darwin-ld" rustflags = [ "-C", """ link-args= -F/path/to/sdk/System/Library/Frameworks -L/path/to/sdk/usr/lib -L/path/to/sdk/usr/lib/system/ -adhoc_codesign """, ] ```

Hmm, could you change this to check if |
This case is already handled and, from what I can tell, is handled before the check against the host operating system: |
