I just downloaded Xcode 6.3 beta 4, and my WatchKit app now fails to build with an error:
Embedded Binary Validation Utility Error error: WatchKit apps must have a deployment target equal to iOS 8.2 (was 8.3) The iOS app and the project actually have a deployment target of 7.1 and always have, but we've been working with the iOS 8.3 SDK for our WatchKit component (using Swift 1.2) without issue using Xcode 6.3 beta 1, 2 and 3. This error only arose with Xcode 6.3 beta 4.
Anyone else have this error, and know how to fix it?

In short, every application that runs on one of Apple's platforms has a deployment target. A deployment target is nothing more than the minimum version of the operating system the application can run on. Fire up Xcode and create a new project by choosing the App template from the iOS > Application section.
Deployment Target refers to the oldest version of iOS that is capable of running your project. To change your deployment target, open up your project file in Xcode and check the setting under Build Settings -> Deployment(...) Check this answer to add earlier devices support.
A WatchKit Extension process that executes the watch app's application logic. This is bundled with your Watch app and runs on the Apple Watch. A Watch app that displays user interface elements and handles navigation.
Select your project settings and go to "TARGETS". Click on your Watch Kit App, select Build Settings. For the key "iOS Deployment Target" you should find "iOS 8.3". For some reason Xcode 6.3 Beta 4 wants to have this on "iOS 8.2" for "Debug" and "Release". Now your project should build as expected.
This is still true for XCODE 6.3 release!
