iOS - Some images not showing up in launch screen

Question

Hi we're having a really frustrating moment with the launch screens (note: NOT launch images).

The problem we're having is that some images appear on the launch screen whilst others do not.

The images are contained in a UIImageView and have some really simple contraints set up.

Here are some screenshots so you understand what we mean:

First pic - A really simple avatar image (one color, RBG, Alpha channel) WORKS

Second pic - A really simple logotype image (one OR multiple color, RBG, Alpha channel) DOES NOT WORK

Third pic - Interface builder look of the second picture. (What we want)

---

Have anyone encountered the same behavior or am i missing something fundamental?

Another interesting thing is that it works as expected in the simulator but not on the actual device?!?

All derived data has been cleared and also the build folder multiple times.

Remember, this is NOT launch images, but rather the launch screen using storyboards.

Also, all assets are in the XCAssets folder.

Looking forward to some clarifications!

Answer 1

keep image file in project navigator instead of XCAssets. That fixes my same issue.

Answer 2

This could be related to the alpha channel on the image. This is discussed on the dev forum: https://forums.developer.apple.com/thread/19759

Answer 3

Turns out that the physical device caches the images regardless if i removed the application or not. The only thing that actually worked was to 1. Remove the application and 2. Reboot the device. Only then the images would disappear. Don't know if this is a bug or not as of iOS 9.2
