Using Appium Desktop, launching my app on iPhone 7 throws an error (see below). I did pass the correct UDID. Appium works fine on the iPhone 5s and iPhone 6s using inspector as well as code.
[XCUITest] Error: Could not install app: ‘Command ‘ios-deploy --id f7f1b2d886ee7f9cfe9727b064b3fe5434716430 --uninstall --bundle /var/folders/f0/stp5z28967v65lqf8yxdfcxm0000gn/T/2017731-27200-1rgytwn.66f4bfn7b9/Payload/SavingStar.app’ exited with code 253’
