GitHub Actions runners for iOS / Xcode

Why this fits

• iOS builds need macOS + Xcode; GitHub's macOS runners are slow, expensive, and capped per org.
• Cirun is cloud-neutral — every supported cloud has at least one SKU that fits iOS / Xcode; pick whichever account you already have.
• Ephemeral by default — no state from the previous PR leaks into yours, no flaky-cache surprises.

.cirun.yml

.cirun.yml

1# iOS / Xcode CI requires macOS. Cirun runs macOS via the on_prem cloud (using a Mac mini / Apple Silicon host you own); image names like `macos-sequoia`, `macos-14`, or `sonoma-latest` select the platform.
2# See docs.cirun.io for the on-prem macOS schema.
3runners:
4  - name: ios-runner
5    cloud: on_prem
6    instance_type: 8vcpu-16gb-80gb
7    machine_image: macos-sequoia
8    labels:
9      - cirun-ios

Drop this in your repo root. The first workflow that requests the runner label spins this configuration up on your cloud account.
