问题
After pod installing NearbyMessages and reinstall the app on the simulator or physical iOS device my app icon goes blank.
I am using swift 3.2 and XCode Version 9.2 (9C40b). I am using NearbyMessages version 1.1.0.

I think when you open the xcworkspace check the app icon folder and see if there is an image in that and does it match the apples guidelines.

In Xcode 11.2, when I install NearbyMessages via Cocoapods, I get an error:
warning: duplicate output file '/Users/.../Library/Developer/Xcode/DerivedData/XXX-bcwvmondqpgllhdzdahpqecjlqca/Build/Products/Debug-iphonesimulator/XXX.app/Assets.car' on task: PhaseScriptExecution [CP] Copy Pods Resources /Users/.../Library/Developer/Xcode/DerivedData/XXX-bcwvmondqpgllhdzdahpqecjlqca/Build/Intermediates.noindex/XXX.build/Debug-iphonesimulator/XXX.build/Script-F8B92903BE89C5535684B7F8.sh (in target 'XXX' from project ‘XXX')
This suggests that there’s some conflict in assets. This might explain app icon issues.
