This is how we setup our teams for React-Native projects. We usually will have the lead for either-or of the Android/iOS teams also be familiar with that platform. For example myself: I was the co-lead for 2 React-Native projects at my company along with a dev who is very familiar with Swift/Obj-C. I'm still much more familiar with JS/TS-land but I was one of the few on the team fairly comfortable dropping into native Kotlin/Java for when we needed to. This worked out well for us. The native iOS dev who worked along with me was less experienced at React/JS/TS itself so I took most of the shot calling for that but having him there for native-iOS help definitely pushed us through points where we would have hit a roadblock for a fairly large project. In the end we had 200k LOC on the React-Native side, and a fairly large amount for both in native due to a large feature that required us to drop into native.
