        Usually when Xcode starts a UI test, it will automatically launch the selected simulator first.

        I have a project in which this is broken: if the simulator is not already open, I get this error:

        "No devices are booted."

         

        • This occurs before the test setup() function is called.
        • If the simulator is already open, everything works as normal.
        • It is local to one specific project and persists if I make a new UI test target in that project
        • The problem does not happen if I make a new project with a new UI test bundle - the simulator launches as per normal.
        • I'm using Xcode 10.2 and have tried resetting simulators as well as reinstalling them.
        • It inteferes with running UI tests in parallel as clones do not launch automatically.

         

        Does anyone know what this could be related to?
