.h not found in xCode

I have a lot of troubles while making first app with EstimoteIndoorSDK. How should look like my catalogue structure after drag-and-drog EstimoteIndoorSDK and EstimoteSDK? Where is the problem if “xxx.h” not found? I’ve read a lot of articles and tried everything and nothing happend. I have mac os 10.11.6 a xcode 8.2.1? It is too old? Please help

Maybe you could try installing via CocoaPods instead:


CocoaPods will automatically get the Indoor SDK and the Estimote SDK, and integrate it into your project.
