## AI overview

Codename One has entered phase 2 of its migration to Xcode 10.1, allowing developers to test builds with that version. Xcode 10.1 is planned to become the default in phase 3, while Xcode 9.2 will remain available as a compatibility option if regressions occur.

## Source excerpt

As I mentioned recently, we're migrating to xcode 10.1. This weekend we entered phase 2 of the migration which allows you to test your builds with xcode 10.1. To do this just set the build hint: ios.xcode_version=10.1. If you run into issues with xcode 10.1 builds let us know ASAP. This is very urgent as phase 3 will kick in this coming Friday. In phase 3 we will flip 10.1 as the default which means that builds sent on Friday will implicitly target xcode 10.1.
