Whenever I add an app Icon to Asset Catalog and run on Device , it gives following error. This happens with every single project even, blank new projects.
Asset Catalog Compiler Error /Users/****/Documents/Test/sfdadfas/sfdadfas/Assets.xcassets: Failed to write image data for the app icon set from "AppIcon.appiconset/[email protected]" to "/Users/*****/Library/Developer/Xcode/DerivedData/sfdadfas-cbhytlfzznzesdsfsgifiloaxklokg/Build/Products/Debug-iphoneos/sfdadfas.app/[email protected]".
But when I run on Simulator , this works fine and app icon is visible correctly.
I'm using Xcode 9.2 (9.1 had the same error) on macOS High Sierra.
Xcode 8.3.3 doesn't have this issue.
EDIT
Full Error on log,
