I use PNGLib in my app to load some of the launch image textures after app launch. Since updating to Xcode 7.3 (release, but beta was the same), PNGLib can no longer load these files as they now appear to use the Apple-specific CgBI format.
It seems that Xcode is choosing to 'compress' these textures when it copies them to the resources, despite the fact that 'Compress PNG Files' is set to No in the project's build settings. Up until now, setting this option to 'No' has always worked.
Has anyone else come across this and/or found a workaround in Xcode?
