*-apple-ios-macabi
Apple Mac Catalyst targets.
Tier: 2 (without Host Tools)
aarch64-apple-ios-macabi
: Mac Catalyst on ARM64.x86_64-apple-ios-macabi
: Mac Catalyst on 64-bit x86.
Target maintainers
Requirements
These targets are cross-compiled, and require the corresponding macOS SDK
(MacOSX.sdk
) which contain ./System/iOSSupport
headers to allow linking to
iOS-specific headers, as provided by Xcode 11 or higher.
The path to the SDK can be passed to rustc
using the common SDKROOT
environment variable.
OS version
The minimum supported version is iOS 13.1.
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 IPHONEOS_DEPLOYMENT_TARGET
.
Building the target
The targets are distributed through rustup
, and can be installed using one
of:
$ rustup target add aarch64-apple-ios-macabi
$ rustup target add x86_64-apple-ios-macabi
Sanitizers
Due to CMake having poor support for Mac Catalyst, sanitizer runtimes are not currently available, see #129069.
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-ios-macabi your-code.rs
Testing
Mac Catalyst binaries can be run directly on macOS 10.15 Catalina or newer.
x86 binaries can be run on Apple Silicon by using Rosetta.
Note that using certain UIKit functionality requires the binary to be bundled.
