I need to use two different GoogleService-info.plist for working with dev and prod builds, currently I'm separating dev and prod by just changing "build configuration" in edit scheme, but now I need to have two different .plist files for dev and prod for working with google analytics, pushwoosh etc,

After that you will can link GoogleService-info.plist for this targets. And also I recommend create different folders in project directory
Look at pictures. The first you create targets Prod and Dev
After create diff folders in project dict let's call them GoogleProd and GoogleDev and copy your .plist file to diff folders and drag to project. First file you need link with TestProd target
And the second file link with TestDev target
The final project directory will look like
