Edit: I've updated the title and question to be more specific.
I'm having trouble getting my app to run on 14.2, it runs without issue on 14.1.
The App loads 'successfully' but I'm left with a blank white screen (assume this is the loading screen) on both simulator and physical device. I get the following error on 14.2:
2020-11-17 12:38:38.090885+0000 TestApp[5191:233822] [framework] CoreUI: -[CUICatalog namedVectorGlyphWithName:scaleFactor:deviceIdiom:layoutDirection:glyphSize:glyphWeight:glyphPointSize:appearanceName:] 'triangle.fill' called with scaleFactor == 2.000000 glyphPointSize == 0.000000 at '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/CoreServices/CoreGlyphs.bundle/Assets.car'
2020-11-17 12:38:38.091306+0000 TestApp[5191:233822] [SwiftUI] No symbol named 'triangle.fill' found in system symbol set
I'm not sure why it's stating No symbol named 'triangle.fill' as that is a valid SF Symbols icon.
Really would appreciate any guidance?
My issue was actually related to using a TabView with PageTabViewStyle. iOS14.2 doesn't seem to like it, and was throwing all sorts of errors my way. I ended up changing my app layout, removing the PageTabViewStyle, and suddenly the 'No symbol named...' error disappeared.
