Dropsource apps are now iOS 12 compatible (backwards compatible to iOS 11). This means iOS apps will now be built in Swift 4.2 and work with Xcode 10.
Note: You’ll need to run a new build on your iOS apps to update your source code to Swift 4.2 and be iOS 12 compatible. Also, please note that iOS 12 compatible apps will only run properly on Xcode 10.
We’ve improved our constraints system to allow for more granular control over how your app’s layout adapts to different device sizes. This improvement includes an updated constraints editor and the introduction of right and bottom constraint options.
In conjunction with our new constraints system, we’ve made updates to how our system generates source code for Android apps. All screen layouts in Android will now use the new Constraints Layout system rather than the older Percent Relative Layout system.
