No symbol named 'xxx' found in system symbol set

Question

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?

Also pay attention to minimum supported version of the chosen asset. I selected an asset that was only available for iOS17 and above. So when testing below 17, I saw blank space and said warning.

Answer 2

Xcode 14. I got the same issue while setting Image in Swift UI. I mistakenly provide the image name with systemName. I was loading image from Assets.

Image(systemName: "magazine-front-cover") //use only to load system image

Instead of this

Image("magazine-front-cover") //use to load Asset image

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.

Same issue for me as well. My app runs great in "all" simulators, my physical iPhone 6s, iPhone X and iPad Air 2, but crashes only on my new bought iPad Pro 12.9" 2020 (all running iOS 14.2) The strange thing is that the error appear when I use TabView in ContentView, directing me to a sub view, containing the "no symbol" mentioned in the error message. By skipping the TabView and access the sub view directly from ContentView, the sub view works great... In addition to this, uploading the app from Xcode to iPad goes very slowly. Turning off "Debug executable" for both "Run" and "Test" (Product/Scheme/Edit Scheme) will help on this process, and sometimes allows my app to run for a few seconds, before it freezes again.
