I would like to ask about UIApplicationOpenURLOptionsKey.When transferring data between applications using the "Open In .." function in iOS12 or earlier and iOS13 or later,The value of UIApplicationOpenURLOptionsKey.sourceApplication seems to be different as follows.------------------------------------------------------------UIApplicationOpenURLOptionskey.sourceApplication before iOS12→ Bundle ID of calling applicationUIApplicationOpenURLOptionskey.sourceApplication for iOS13 or later→ "com.apple.sharingd" always regardless of which application is called------------------------------------------------------------Do you know the reason why the value of sourceApplication is fixed like this?
