I have a very simple application with a single view, containing several UILabels. Upon running in Simulator, the Xcode console returns the error:
libM
Am seeing this problem. Using Xcode 10.1. Created a brand new project - doesn't do anything except show a white screen. Discovered it was showing up on simulator for older devices. For example, iPad Pro (12.9 inch) and iPad Pro (12.9 inch) (2nd generation) show the problem, but problem is gone for iPad Pro (12.9 inch) (3rd generation). Does not show up for iPhone XR simulator.
Basically seems annoying.
