Xcode keep using old framework version
it seems problem with binding in new framework, your project still linked with old framework files.try to remove all files and folder related to your "custom.framework and also remove path for that framework from project setting--> build setting --> search Path
Then after Drag and Drop Your "custom.framework" files in project.
it works for me.hope it resolve your problem.
Please try to clear derrived data:Window -> Organizerat the right side you will see projects list. Find your project and tap on it. I the top part of window you will see button delete in front of Derrived data, tap on it.
I guess it will solve your problem.
It might sound silly, but sometimes restarting XCode or the whole machine fix things.
Did you remove the old framework from Build Phases --> Link Binary With Libraries?
