The Xcode images are preinstalled with recent versions of the simulator runtime. A list of the simulator runtimes, along with simulator devices, can be found in the image manifest.
Adding a simulator runtime
If a different simulator runtime is required for your tests, you can use the xcode-install gem to download these within your job. For example:
-run: gem install xcode-install
-run: xcversion simulators --install="13.2"
Please note that downloading additional simulator runtimes may increase build times.
Creating a new simulator
If you need to create a specific simulator combination that is not provided by default, you can create these with the
xcrun simctl create command. An example may look like this:
-run: xcrun simctl create 'iPhone 11 (13.2)' com.apple.CoreSimulator.SimDeviceType.iPhone-11 com.apple.CoreSimulator.SimRuntime.iOS-13-2
