### Galway Bus Kotlin Multiplatform project using Jetpack Compose and SwiftUI


**Note**: if you are trying this project out and aren't in Galway then hit the home icon in title bar to center in Galway so you can see meaningful data!


### Kotlin Multiplatform

This project also acted as initial platform I used when starting to explore **Kotlin Multiplatform**
capabilities. There's a Kotlin Multiplatform `ShareCode` module for example along with sample iOS
and macOS apps. Also wrote a couple of posts about some of my experiences using **KMP** in the project.

### Google Maps SDK

The project depends on `GOOGLE_API_KEY` environment variable to be defined for maps functionality to work.  Alternatively
you can update where this is read in `build.gradle`
