**EDIT : note that this issue is now resolved in `Xcode 9.3`, hourrah !**

**OK, it's a Xcode bug, but does anyone has a workaround for this ?**

Since I made the update to `Xcode 9` and compile my app, I get a bug with my images. All images in my app get distorted, only on `iOS 8`. I have to point out that when recompiling the exact same project with `Xcode 8`, **every image shows well** !

Here is my launch screen when my app is run on `iOS 8`, then on `iOS 9` (or 10 or 11), both with `Xcode 9`.

I know that some people encounter this bug with `Xcode 8 beta 6` ([Xcode 8 simulator ios 8 image get distorted](https://stackoverflow.com/questions/38972093/xcode-8-simulator-ios-8-image-get-distorted "Xcode 8 simulator ios 8 image get distorted") and [Xcode 8 beta 6 - App image broken in iOS 8](https://stackoverflow.com/questions/39094618/xcode-8-beta-6-app-image-broken-in-ios-8?noredirect=1&lq=1 "Xcode 8 beta 6 - App image broken in iOS 8")) but they say this was a Xcode bug that was resolved in `Xcode 8 GM`. I can't find anybody having this issue in `Xcode 9`. 

`Xcode 9` brings many changes to images assets, so I've tried to play with them (ticking "Preserve Vector Data", changing to "Individual scales" etc) but it didn't helped. 

I'm using `Xcode 9.2 (9C40b)`, which I think is the last Xcode version available.

Does anybody has a clue for this ?
