Realm Kotlin SDK is GA 🎉

Two years ago, we started tinkering on a Kotlin-first SDK as a cornerstone of crafting new Android and KMM applications. It all started on this whiteboard in the Copenhagen office.

400~ pull requests later, we are pleased to announce the release of Realm Kotlin 1.0.0! This marks the general availability of the SDK.

We did our best to keep the API simple to use while addressing existing Java SDK limitations like:

• Threading
• The realm lifecycle
• Testability

You can check out the full list of features here.

We noticed a rise in Kotlin Multiplatform usage and designed the SDK to support KMM and KMP targets. Check out a sample here.

If you’re an existing Java SDK user, we hope that you’ll notice how easy it is to migrate to the new Kotlin SDK. We prepared a small quick start guide to help in this journey.

We can’t wait to see what amazing applications you will build! Please share your story and feedback with us on Twitter or GitHub.
