how to solve this  problems

Same Problem here.

same issue. Hope someone can help.

Same here, can't builing the samples. Using the folder structure shown in the faq ending in endless error list. Trying to unpack the Samples direct to the Samples folder, getting the "Vuforia/Vuforia.h" not found error.

Using XCode 7.3 too.

With best regards

EDIT:

Solved. Connecting iPhone/iPad is solving all the problems.
