Question

1. I change the search for user path to yes

3. I restart Xcode but autocomplete didn't call my class proprety

Answer 1

Try this: close your project and your Xcode; Right click on the project and select the Show Package Contents, then open xcuserdata folder and delete the [username].xcuserdata folder. Open the Xcode, clean your project and build it once for device (not for simulator). It worked for me.
