I have everything installed as indicated in your tutorial.
Like I said, it DID work and now after the 3.60 update it gives the error stated above.
I even tried reinstalling everything with no luck.
I used the GoogleMaps.bundle and GoogleMaps.framework from your tutorial and also tried the latest framework and bundle from Google.
Both give the same error.
I have OSX 10.11.6 running with XCode 7.3.1
My java version is 1.8.0_121
Since B4i is reporting it cannot find the file GoogleMaps.h', what is suppose to be supplying this missing file?
