Fresh React Native project failing: Entry, ":CFBundleIdentifier", Does Not Exist

I'm trying to set up a fresh React Native project by simply following the guide here: https://facebook.github.io/react-native/docs/getting-started

I can build and run it from Xcode just fine, only getting a few "semantic warnings".

When I run yarn react-native run-ios though, I get the following error:

Leos-MacBook-Pro:citymysteryrn leo$ yarn react-native run-ios

I know there are tons of questions (and answers) related to this, but it seems to be a very broad issue that I can't solve. I've tried most things on Print: Entry, ":CFBundleIdentifier", Does Not Exist without any luck.

I've also tried comparing this project to older React Native projects that I know are running and have identified the following differences, but don't know if they are of any importance:

• Missing folder third-party in node_modules/react-native/
• Build folder contains folder ios/build/MyProjectName containing Logs, info.plist etc, while older projects have these files and folders directly in ios/build/

Here's the output of yarn react-native info
