When I open the Simulator "Settings" on the Home Screen they open and then crash before loading. The same thing happens when I open other built-in apps like Safari. Otherwise, the simulator behaves normally and I am able to run test apps I've created.
A restart of Xcode, Simulators, and computer didn't fix the issue. Erasing all contents and settings didn't work. Starting up different simulators doesn't work.
I just updated Mac OS to Mojave 10.14.4, which may or may not be playing a role.
Short of re-installing Xcode is there anything else I can try?
UPDATE: I just tried a re-install and it didn't fix the simulator either, so now I've no idea what to do. Hopefully this get fixed in a future Xcode update?
