The app consists of UIWebView written in Swift without any splash screen. After updating from app store shows blank white screen in iOS 12.1 but after deleting and reinstalling the app from app store works fine.
As I cannot share the code, logic implemented in App Delegate includes :
1) On first time, app waits for 3sec to get the device token n store it locally into device. Using the same device token as query string is passed to UIWebView to loadUrl.
2) On second time, app checks for the fresh device token n matches with the existing token. If same, then saved device token is send as query string to UIWebView else new device token is replaced n send to UIWebView to loadUrl.
Why So please suggest as on all other versions app running fine.
