In December, we announced that our Unified API, which brings 64-bit support to our Mac and iOS products, would be released to stable on January 5th to accommodate Apple’s requirement that apps must be built with 64-bit support beginning February 1st. However, based on Apple’s mid-December announcement that published apps may continue to submit 32-bit-only updates until June 1st, we made the decision to push the stable release of our Unified API to next week. This will enable us to fully incorporate feedback from you to ensure the highest quality developer experience.

Migration

Migrating to the Unified API is simple, and even the most complex apps should not take more than a few hours to migrate your source code. Customers can begin migrating their apps next week, when the Unified API has been released to stable, along with Unified API updates to Xamarin.Forms and all of the Xamarin-maintained Components in our Component Store. If you are a library developer, or are just interested in getting a head start with Unified API, you can grab the release currently in our Beta channel and get started updating your libraries and apps today. For some guidance on migrating your app to Unified API, please check out the full guide on our documentation site, or check out this Xamarin University Lightning Lecture:
