**Catalina** with Xcode 11.4 beta is now available! 🎉
**To select this Stack** you just have to **open your app** on [bitrise.io](https://www.bitrise.io),
go to the `Workflow` tab (Workflow Editor), and on the `Stack` tab select the `Xcode 11.4.x`
option and your next build will start on the Xcode 11.4 stack.
_Note: you can now select separate stacks for separate workflows!
