| Xcode 16 Beta Now Available on macOS Runners

By David Chavez | June 19, 2024 [Product]

Update, October 2026: this post describes the 2024 beta setup. Today each macOS image carries one Xcode: blaze/macos-15 has Xcode 16.4 and blaze/macos-26 has Xcode 26.2, and macos-14 is retired. See runner images for what’s installed now.

The latest Xcode 16 beta is now available on Blaze, allowing you to test your apps and prepare for the upcoming OS releases. We update the Xcode 16 beta as new versions are released, so you can stay current with the latest features and improvements.

Using Xcode 16 Beta

To use it, specify our macos-15 runner and use the xcodes tool to select Xcode 16. Here’s an example workflow:

jobs:
  xcode-16:
    runs-on: blaze/macos-15
    steps:
      - uses: actions/checkout@v4
      - name: Select Xcode 16
        run: sudo xcodes select 16.0
      - name: Build and test
        run: |
          xcodebuild build             -project MyApp.xcodeproj             -scheme MyApp             -destination 'platform=iOS Simulator,name=iPhone 15 Pro'

Why Use Blaze for Xcode Builds?

Our macOS runners run on Apple Silicon Macs:

  • A fresh 4-core, 12 GB VM on an Apple M2 Mac for every job
  • Xcode pre-installed in the runner image
  • Unlimited minutes at a fixed monthly price

Pre-installed Xcode Versions

Our macOS 14 runners come with multiple Xcode versions pre-installed:

  • Xcode 16.0 Beta
  • Xcode 15.4
  • Xcode 15.3
  • Xcode 15.2

Switch between them with xcodes select.
