Problems with EstimoteIndoorSDK Release 3.0.0-alpha.1

Hi I am trying to use arkit with estimote and add to my pod EstimoteIndoorSDK Release 3.0.0-alpha.1 but I am unable to use ESTConfig or any class inside EstimoteSDK in my viewcontroller.
How can I resolve this? Any suggestion?

Maybe you’re missing an import for the Estimote SDK?

#import <EstimoteSDK/EstimoteSDK.h>

// or if you only want to import ESTConfig:
#import <EstimoteSDK/ESTConfig.h>

Thanks Heypiotr, i will test it.
