I just converted my iPhone app yesterday to a universal app. I made the appropriate changes, but everytime I add new png files or icons, it gives me this error:
No such file or directory (/Users/username/Library/Developer/Xcode/DerivedData/APP-exqfnpxyqlazbechywnebtxqcykj/Build/Products/Release-iphoneos/APP.app/APP)
I am not sure what is causing this. I keep following the steps described in this blog. But it doesn't work. I've even tried resarting my computer several times. Does anyone have an idea what's going wrong?
