I had this problem recently. I don't know about the missing frameworks, but if you go to your project folder within terminal and modify the permissions on the project files, you should be able to open the project. I personally had to modify multiple files and folders to be able to get it to stop asking me if I want to unlock my files.
Steps that Worked for Me:
Use the terminal to go to the folder that contains the xcworkspace file. Type
sudo chmod 777 NameOfYourWorkspaceFile.xcworkspace
(Please don't literally use that file name unless that's what your xcworkspace file is called). This should change the permissions for your entire workspace, but you will still have the unlock problem with your Pods project.
From within the same directory, you can do another chmod on the Pods folder like so:
sudo chmod 777 Pods
After that, go into your Pods folder by typing "cd Pods" and then modify the permissions on your Pods.xcodeproj file as so:
sudo chmod 777 Pods.xcodeproj
Like I said previously, these permission changes were enough to get xCode to stop asking me if I want to unlock my projects. I don't know if it will be enough for you though. Hopefully it helps!
