Xcode 9.2 image in image.assets was broken on iOS8

image was displayed like this (twisted):

And the origin image:

Another issue: app cannot be compiled on iPhone5(device).

error code is:

Command /Applications/Xcode.app/Contents/Developer/usr/bin/actool failed with exit code 255

I have the same problem. Could you figure out how to solve it?
