I wanted to give a little bit of a discussion on all my thinking about why UI's are a tricky to get right in Rust. I want to try and differentiate this discussion because there are a number of decent UI frameworks that have been bound to Rust. This is great! I do not want to discourage any of their work, they are wonderful members of our community.
What this is about is how it would be possible to write a good UI framework
This is for my personal use, things might not be correctly explained here. For the official docs please check https://github.com/airbnb/react-native-maps
After installing react-native-maps from npm:
Drag this folder node_modules/react-native-maps/lib/ios/AirGoogleMaps/ into your project, and choose Create groups in the popup window.
In xcode, right click on Libraries -> Add files to [your project], and navigate to and add node_modules/react-native-maps/lib/ios/AirMaps.xcodeproj. Select Copy files is necessary and Create groups.
