Make sure you unzip the SDK with something which understands symbolic links.
GoogleMaps.framework/Headers
is a symbolic link to GoogleMaps.framework/Versions/A/Headers
.
When I unzip it on my Mac the symbolic link is set up correctly. But when I unzip it on my PC instead of symbolic links I get text files which just contain the path (eg Versions/Current/Headers
).
If you unzip on a PC and then copy the folder to your Mac (or unzip using some other method which doesn't create symbolic links), then you will get the error you see.
