Cleaning Up
Stop your Vapor project to stop the Vapor server.
To stop the PostgreSQL database, head to the Terminal window where docker-compose is still running, and type Control-C.
To remove the images and containers created by docker-compose, in Terminal, in the same directory as your docker-compose file, run:
docker-compose down -v --rmi all --remove-orphans
Where to Go From Here?
You can download the completed project files by clicking the Download Materials button at the top or bottom of the tutorial.
In this article, you’ve learned how to create a library to share Swift code between server-side apps and iOS apps! You’ve built a shared library using SwiftPM. You’ve also learned how to integrate the library into an iOS app and a Server-Side Swift app.
Now that you have code shared between two different apps, try adding new properties to the models and see how easy it is to keep them working together.
If you’re looking for a challenge beyond the scope of this article, here are a couple things you can try:
- Migrate
Endpointsto the shared package, similar to what you did with the API models. - Share
TILErrorfrom the Vapor project with iOS.
