Xcode Error on Simulator: MGIsDeviceOneOfType is not supported on this platform

Question

I have a very simple application with a single view, containing several UILabels. Upon running in Simulator, the Xcode console returns the error:

libM

Answer 1

I have recently updated to Xcode 10.2 and when I tried to run a project created in earlier version, Same error occurred.

The problem was that simulator was running before updating Xcode.

Solution was very simple for me to quit Simulator and restart so that it can get the new changes. I don't think the model of the simulator (iPhone SE or iPhone X) matters. You just need to restart your simulator for it to take effect of new update.

I would recommend to quit both Xcode and simulator and restart your Mac.
