* fix(cli): iOS dev broken on Xcode 16.3, closes #13128 Looks like we cannot use the arm64-sim custom architecture on Xcode 16.3, as it incorrectly appends the -sim suffix on some clang build scripts which ends up with an invalid target triple. Currently we do not have automation to update Xcode/Android projects, so a manual intervention is required by our users, either recreating the project or modifying it manually (the arm64-sim arch must be removed and all its references). ref tauri-apps/cargo-mobile2#445 * fix dev on macOS with intel chip

+Fixes iOS dev not working on Xcode 16.3 simulators. To apply the fix, either regenerate the Xcode project with `rm -r src-tauri/gen/apple && tauri ios init` or remove the `arm64-sim` architecture from the Xcode project.
