Summary:
If you create a new SpriteKit project in Xcode with a hyphen in the name, then attempt to run it without modification, it will fail.

Steps to Reproduce:
1. Go to File > New… > Project
2. Select "Game" Under Application and hit Next
3. Set "Project Name" to a name with a hyphen
4. Make sure "Game Technology" is set to "SpriteKit"
5. Make sure "Integrate GameplayKit" is checked
6. Hit Next, then Create
7. Go to Product > Run

Expected Results:
Project starts and displays "Hello, World!"

Actual Results:
Xcode returns "signal SIGABRT" error in Thread 1 with description "Could not cast value of type 'SKScene' (0x10949c530) to '<projectname_withunderscore>.GameScene' (0x10878e700)."

Version:
Xcode Version 8.3.1 (8E1000a)
macOS Version 10.12.4 (16E195)

Notes:
A project exhibiting this problem is also attached. Explicitly setting "Module" to "withahyphen_ios" for the "Scene" node in "GameScene.sks" fixes the issue.

Configuration:
Going to "GameScene.sks" and explicitly setting the "Module" field in the Custom Class Inspector of the "Scene" node to the project name with the hyphen replaced with a underscore resolves the issue.
