Google Maps not working on iOS and TestFlight

I will be forever indebted and grateful to anyone who can share with me or point me in the right direction on how to make interactive maps from Airbnb on iOS TestFlight.

Currently following the instructions from the Responsive Maps tutorial it is not possible to use this example in the repo to make it work on the simulator, but when I click on TestFlight the app crashes instantly.

Again, I will be forever indebted to everyone who can help me solve this!
