Xcode 14.3 Rosetta build with command line

As Apple removed x86_64 support for Xcode and introduced sperate simulators for Rosetta, I wondered how I could run my app on a Rosetta simulator via cli.

This is also needed for fastlane. (see Fastlane Issue)

In the release notes of Xcode 14.3 nothing regarding the cli is mentioned. (Release Notes)

    According to the Github Issue which I opened for fastlane as well a user pointed out that following command can be used to build for Rosetta Simulator.

    xcodebuild -workspace App.xcworkspace -scheme App -destination "platform=iOS Simulator,name=iPhone 13,arch=x86_64" build

    Fastlane

    There is a new run_rosetta_simulator option on scan now.

    for Xcode 14.3 + please follow this to Open using Rosetta in Xcode 14.3+

    To run an app on a Rosetta simulator, you need to do the followings.

    1. Go to the "Product" menu in the menu bar and select Destination > Destination Architectures > Show Rosetta Destinations.
      You will see architecture in parenthesis next to the simulator. In this case, it is Rosetta.
    2. You will see a Rosetta architecture in parenthesis next to simulator names.

    If you want to run on both architectures, select the "Show Both" option.

    • Go to the "Product" menu in the menu bar and select Destination > Destination Architectures > Show Both.
