I am running Mac OS X Mojave 10.14.6. The only app I have installed is a freshly downloaded Xcode 11.1 GM Seed (11A1027). There are no prior files, projects or apps on this system, as I just wanted to start learning Swift programming.
In Xcode, I have created a fresh project for a single view iOS app. I compiled it without any changes, the build was successful. By default, it launches an iPhone 11 Pro Max on iOS 13.1.
The Simulator launched, the device window appeared and a progress bar was going for a while. After some time, a spinning indicator appeared on a black screen, but nothing ever happened. This went on for a couple minutes, after which Xcode showed this error:
The request to open "com.example.FoodTracker" failed. Unexpected error type.
Details:
The request to open "com.example.FoodTracker" failed.
Domain: FBSOpenApplicationServiceErrorDomain
Code: 5
Failure Reason: Unexpected error type.
User Info: {
BSErrorCodeDescription = InvlaidResponse;
}

The operation couldn't be completed.
(BSServiceConnectionErrorDomain error 3.)
Domain: BSServiceConnectionErrorDomain
Code: 3
User Info: {
BSErrorCodeDescription = OperationFailed;
}
--
I left the device running in Simulator for quite some time but it never stopped spinning.
I have tried reinstalling Xcode, I deleted the DerivedData directory, did a clean build, reinstalled some Xcode components, but I think there is no issue with Xcode, or the project itself.
In the Simulator, I also tried to "Erase All Contents and Settings", quite a few times, to no avail. I tried starting new devices and an iPhone 6s on iOS 12.2 loaded successfully on the first try. On the other hand, I kept trying iOS 13.1 with iPhone 11 Pro Max and iPhone 8 devices, but both get stuck after some loading.
Sometimes I also get this: SpringBoard quit unexpectedly. When I check the details, it seems that a SIGILL terminates it.
Anytime I start an iPhone 11 Pro Max device with iOS 13.1, it keeps spinning endlessly. After checking the system logs, I noticed that the same messages keep looping with ~5s delays inbetween:

I've spent all day googling for solutions but nothing helped so far. I guess in the meantime I will just start developing for 12.2, assuming that the basics are not too different. Although Xcode clearly generates code for 13.0+ and it yells at me that "some", "View" and such are for newer versions.
