 ## Build
 
+### iOS Only: Copy System DB 
+
+The `system.db` from the pEpEngine repository must be copied in the bundle that uses the pEpObjCAdapter.a static lib. The ObjCAdapter copies it at runtime in the desired directory.
+
+Backround: Has been introduces to use Apple Shared App Directory of the client App.

 ### Using Xcode UI
 
 `open pEpMacOSAdapter/pEpObjCAdapter.xcworkspace/`
