Hi @Minishlink and thanks for asking this here! 
We definitely plan to have a better answer for this question, but we’re still discussing a couple of details. Our schedule right now is to start working on full React Native and Ionic/Cordova support early next month, starting with creating up to date sample projects and base workflows, and then decide what should be preinstalled and where.
Once that’s decided we can move on to auto detect RN/Ionic/Cordova projects, auto selecting the right stack and auto generating a suitable base configuration, just like what’s available for iOS, Android, Xamarin, MacOS, fastlane, … projects right now.
In the meantime, if anyone have any feedback please let us know!
Particularly we’re interested in:
- If we create a separate “cross platform” stack (Xcode + Android SDK combined stack), should that be built on the latest Xcode and latest NodeJS version? Or should we use the latest LTS NodeJS version instead? E.g. right now, should we use NodeJS v6 or v7? Similarly, should we use the latest Xcode version which is 8.2.1 right now?
- Should we provide multiple stacks or would a single one be sufficient?
