GuidedTour.playground not opening in Xcode 6.3.2

Are you trying to open the guided tour in the prerelease documentation in Xcode 6.3.2? This error would be expected because the playground has been updated for Xcode 7 and Swift 2.0. Make sure you download the guided tour playground from the non-beta documentation if you want to run it in Xcode 6.3.2.

I've tried opening the guided tour playground in Xcode 6.3 (the one linked in the first Swift book) and my Xcode crashes.

Edit: Just tried opening the new guided tour (from the Swift 2 book) in Xcode 7-beta and that also crashes! Yikes.

Yikes. Can you file a bug report with a crash log attached (from Console.app) and post the radar number here? I'll take a look.

The version from the old 1.2 Swift book works for me in Xcode 6.3.2, but the version linked to from the current (prerelease) Swift 2 book appears to be corrupted and missing files inside the playground package.

It opens properly in Xcode 7 beta as well, it just has errors due to the changes between Swift 1.2 and Swift 2.

If you open the Swift 2 version's package, it doesn't seem to contain any Swift files at all (and no Pages or Source directories, like the newer format).

This is the "contents.xcplayground" file:

<?xml version="1.0" encoding="UTF-8"?>
<playground version="1.0" sdk="macosx" allows-reset="YES">
  <sections>
    <documentation relative-path="section-1.html"/>
    <documentation relative-path="section-2.html"/>
    <documentation relative-path="section-3.html"/>
    <documentation relative-path="section-4.html"/>
    <documentation relative-path="section-5.html"/>
    <documentation relative-path="section-6.html"/>
    <documentation relative-path="section-7.html"/>
    <documentation relative-path="section-8.html"/>
  </sections>
</playground>

So I'm pretty sure the problem is the corrupted playground file, and not the Xcode 7 beta (although it should handle a corrupted playground more gracefully).
