Old Launch Screen and black display after iOS app update

Question

I made an iOS app with Xcode and Swift. In v2, I also updated Launch Screen and Launch Images.

I first installed v1 of my app from the App Store. When the new, v2, was available from the App Store I updated my app on my devices. That's an iPhone 5s with the newest iOS and an iPhone 7 Plus with the newest iOS.

After updating my app on the iPhone 7 Plus it still showed up the old Launch Screen. Restart didn't help. I had to delete and reinstall the app to get the new Launch Screen shown up.

On iPhone 5s I didn't get any Launch Screen or Launch Image, I got a black screen for the time the Launch Screen shot get shown. I deleted and reinstalled the app. That didn't help. I also had to restart the device after reinstalling the app to get the right v2 Launch Screen.

Why that strange behavior? What can I do? I cannot ask my users to reinstall the app and restart the devices.

Answer 1

• After updating the Launch image, delete the application cache which is stored in DerivedData folder.

• If you are using xib or storyboard for displaying LaunchScreen move the images into an asset catalog, rather than using the png filenames.

Answer 2

The only workaround that works for me was to add the images outside Images.xcassets folder. After modified this and rebuild the app, it worked expected.
