Classification:Incorrect/Unexpected Behavior Reproducible:100%
The latest "Swift Playgrounds Author Template for Xcode 11.3" available on developer resources, cannot be built with Xcode 11.3. This is true because the "PlaygroundSupport.framework", and "PlaygroundBluetooth.framework" provided with the sample are built with Swift 5.1 and cannot be imported to Swift 5.1.3

Please list the steps you took to reproduce the issue:
- Download the resource at https://download.developer.apple.com/Developer_Tools/Swift_Playgrounds_Author_Template_for_Xcode_11.3/Swift_Playgrounds_Author_Template_for_Xcode_11.3.xip
- Extract the content of the XIP
- Open Template/PlaygroundBook.xcodeproj on Xcode 11.3
- Try to run either "PlaygroundBook" scheme, or "LiveViewTestApp" scheme

What did you expect to happen?
The project should be able to build, and show the content of the Playgrounds Book

What actually happened?
The project fails to build with the error:

"[...]/Swift_Playgrounds_Author_Template_for_Xcode_11.3/Template/PlaygroundBook/Modules/BookCore.playgroundmodule/Sources/LiveViewSupport.swift:9:8: error: module compiled with Swift 5.1 cannot be imported by the Swift 5.1.3 compiler: [...]/Swift_Playgrounds_Author_Template_for_Xcode_11.3/Template/SupportingContent/PlaygroundsFrameworks/maccatalyst/PlaygroundSupport.framework/Modules/PlaygroundSupport.swiftmodule/x86_64-apple-ios-macabi.swiftmodule"
