I've been developing my app and was running fine until iOS8. However, today after updating my phone to iOS9, I saw that the launch screen of my app became black. The same issue happened to some other apps as well (Anyone else can also see this in on a device running iOS 9).
Any idea why this may be the case? How can I fix this?
I has same problem. and in my case was fixed do a re-install from the App Store.
Here's the solution: downloaded xcode 7, updated my code to swift 2, recompiled the app and problem solved.
