incompleet documentation Integrating with Swift projects which use 'use_frameworks!' in the Podfile

This has been an issue for years at this point, and it looks like "progress" has been made, but the documentation is at best incomplete.

https://github.com/googlemaps/google-maps-ios-utils/blob/b721e95a500d0c9a4fd93738e83fc86c2a57ac89/Swift.md

OK, so we can't use ```Google-Maps-iOS-Utils```, and supposedly there is a workaround... except the documentation is not complete.

Let me be more clear
```
In your project create a group named 'Google-Maps-iOS-Utils'.
```
In the main installation.md do we just say ```add required import for GoogleMaps```; NO, we give the lines of code and specifically site file to add to and so on.

## **Describe the solution you'd like**
Each step of this ```fix``` needs pictures and code examples of where to click and how to add each of these steps.

**Describe alternatives you've considered**
What should have LONG SINCE happened is ```pod install``` worked, I get it is a mess, and Apple Siplicone created problems, but it has also been years at this point.

**Additional context**
While I understand if you waste hours to weeks googling for how to do each and every one of these steps, you would probably eventually figure it out, this is a "workaround" for ```pod install" and or one line of code in the ```podfile``` not working:

The documentation should frankly presume at least half the people reading this
- have never created a group in their project
- and presume what level or where you want it is UNKNOWN
