Your machine
A whole Mac, not a slice of one
Nobody else uses the machine while it is yours, so Xcode behaves exactly as it does on a Mac on your desk.
- The whole machine is yours for the session: a physical Mac, not a virtual one
- Xcode is installed, with the iOS Simulator and Instruments that come with it
- Full administrator access: add Homebrew, Fastlane, CocoaPods or anything else you use
- Archive in Xcode and upload to TestFlight with your own App Store Connect account
- Runs macOS Tahoe, Apple's current release
