Installation

The installer downloads the latest release, adds xcross to PATH, and lists anything missing. Builds ship for Windows x64 / ARM64 and Linux x64 / arm64. On Windows on ARM it picks the native ARM64 build, even from an emulated x64 PowerShell.

curl -fsSL https://raw.githubusercontent.com/arxdeus/xcross/main/install.sh | sh

Then#

1. 1
   Install prerequisites

   $xcross setup

   On Linux, Swift 6.4+ first. On Windows it can install Swift for you. See Requirements.
2. 2
   Extract the iOS SDK

   $xcross sdk install ~/Downloads/Xcode.xip

   Once per Xcode archive. Open a new terminal first so the new PATH applies.
3. 3
   Verify

   $xcross flutter doctor

   Or xcross compose doctor in a Gradle project.

Watch it#

Where it goes#

Pin a version with XCROSS_VERSION=v2.0.2 on either host.

Verify a release#

Every archive carries a SLSA build provenance attestation tying it to the commit it was built from. SHA256SUMS.txt sits next to the archives for plain integrity checks.

gh attestation verify xcross-linux-x64.tar.gz \
  --repo arxdeus/xcross \
  --signer-workflow arxdeus/xcross/.github/workflows/release.yml

Update, completion#

xcross update                      # verified self-update
xcross completion >> ~/.bashrc     # or ~/.zshrc
