Same issue here. Custom fonts in SwiftUI views stops rendering after usin app for a while and some default platform font is shown instead. This is weird because fonts are shown correctly at first. In UIKit views fonts are shown correctly.

Same issue here. Xcode 14.0 + iOS12.0. Termination Description: DYLD, Library not loaded: /usr/lib/swift/libswiftCoreGraphics.dylib No problems with Xcode 13.4.1 + iOS12.0
