Product:Xcode Product Version:Xcode 9.2
Classification:iOS SDK Reproducible:YES
 
We adopted the Xcode 9.2 (9C40b) and found that apps built with it might show twisted image assets on iOS 8.1-8.3 devices/simulators.

This prevents our app submission using Xcode 9.2 so it's a severe issue, and it greatly affects the usability of the App for users on iOS 8.1-8.3.

The issue is not specific to our app. We have verified the issue using Apple sample project listed here: https://developer.apple.com/library/content/samplecode/MoveMe/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007315

The attached screenshots show 1 incorrect version of iOS 8.1 with twisted images, and 2 correct versions on iOS 8.4 and iOS 11.2.

Verified the issue is not reproducible using Xcode 9.1.

Asset Catalog Known Issues When using Xcode 9.2 to create apps that deploy to iOS 8 and later, images in the asset catalog may be corrupted when viewed on devices running iOS 8.3 and earlier. (35379713) Workaround: Build the app using Xcode 9.1, or use Xcode 9.2 and set the deployment target to iOS 8.4 or later.
