I think I found a solution, I tested myself through yourway and found the same error. So I went through one installation of pod, and it worked fine, but the " pod" Google-Maps-iOS-Utils " " causes an error, instead putting it in your click, deleting it and keeping it three under your purpose.
pod 'GooglePlaces'
pod 'googlemaps'
pod 'PopupDialog
Install them, it will be perfectly installed.
Now, in the terminal, when all the dependencies are installed successfully, run "pod try Google-Maps-iOS-Utils", it will start the installation, then you will get options for:
1: samples /ObjCDemoApp/ObjCDemoApp.xcodeproj
2: samples /SwiftDemoApp/SwiftDemoApp.xcodeproj
3: workspace /GoogleMapsUtils.xcodeproj
Which project do you want to open? select your number (e.g. 3), then press enter
Here you have chosen your project and act accordingly. (U) and you did it.
