I seem to have lost the SpriteKit scene editor. Help!

For some reason, when I select an .sks file in the navigator, the editor for the scene doesn't show up. I do see the scene hierarchy, which usually appears on the left in the editor, but the actual scene, showing the sprites, labels, etc., is entirely missing.

Is there some setting that causes .sks files to not be shown that I need to change? I've updated to the newest release, and cleared out the Xcode preferences in ~/Library/Application Support/Xcode, but the problem persists.

[Edit] I have gotten it back. It may be the result of issuing a defaults delete com.apple.dt.Xcode command, but I'm pretty sure I tried that before without an effect. The issue returned, and I issued that command again, and it seems to be working now. But something is causing the issue to crop up intermittently, and I'm not sure what's causing it.

This just happened to me... I can't figure out how to get it back. All i did was press command+T and it disappeared. Can you explain what "issuing a defaults delete com.apple.dt.Xcode" command is?
