Artifacts on iOS 8 simulator when using xcassets

Question

I'm facing a strange issue, after adding all my images to a xcasset, my app looks malformed (see screenshot) when running it on iOS 8 simulator. Each image is full of artifacts. Before, all my images were simply added to main bundle, and everything worked. I don't have a device with iOS 8 to test on it. Also it works well on versions above iOS 8. If you have any guesses what is the problem, please tell me.

Did you try to erase content and settings from the simulator? Are your assets vector- or pixel-based? — Tamás Sengel, Dec 15 '17 at 15:44
@the4kman resetting simulator didn't help. My asset is pixel based. — iOS Dev, Dec 15 '17 at 15:46
I suspect the images themselves are corrupted or somehow in a format not expected by iOS. Maybe try re-exporting the images? Are they JPG or PNG, or something else? — picciano, Dec 15 '17 at 15:49

Ideal is to support three iOS versions, the current version and the previous two versions.

Try below steps:

Remove all caches from User's Library
Remove all derived data content of Xcode
Clean
Clear Trash
Quit Xcode
Open Xcode
Build

It should help you.

Currently 92% devices are running iOS 10 or above

If the images do not contain alpha channel - try adding it, otherwise try removing it.

Also check this option (causes similar problems from time to time): How can I skip compressing one PNG?
