Can't open Swift Guided Tour Playground

Question

当我试图从Apple的电子书打开Swift Guided Tour游乐场时，它说“文件无法打开，因为它是来自Xcode的新版本。据我所知，我正在使用最新的非-Beta版本，我还没有使用Swift 2.0，还在学习第一个版本。所有游乐场都已经更新，可以使用Xcode 7 Beta或者什么？我正在使用Xcode 6.3.2，以防万一实际上是最新版本。

Answer 1

I got the same issue with xcode 6.3.2. I got the issue when I downloaded it via ibook link. Once I downloaded it via we, it worked. https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/GuidedTour.html#//apple_ref/doc/uid/TP40014097-CH2-ID1

My previous version was playground version='1.0' and the new one also same. But it includes lots of new libraries.

Answer 2

I got that problem too, and finally i open it OK, that just problem with where you download your .playground file:

@Xcelleratr Download your file here:

https://developer.apple.com/library/mac/documentation/Swift/Conceptual/Swift_Programming_Language/GuidedTour.html

It will be OK my friend :)

Answer 3

works for Xcode version:

Version 6.3.2 (6D2105)

Version 7.0 beta (7A120f)

Im guessing it was corrupted could check it by: Right clicking on the playground file > show package contents > open contents.xcplayground in a text editor like sublime and look for playground version='3.0' near the top

If this is any higher it will pop up with the error you seen.

Answer 4

Just in case someone stumbled upon this problem, here is what happened to me:

1. Download from guided tour page .
2. Save it with .zip extension instead of .playground, as seen in this picture:

3. Double click the downloaded file, it will unzip it and you'll get your actual GuidedTour.playground file.

Answer 5

So if you have a playground file and it only opens xcode and not a guided playground, right click the playground fle and show package contents, then go to contents.xcplayground and rightclick and open with text editor.

I had to change this line...

display-mode='raw'>

to ....

display-mode='rendered'>

then save and when you go back and open the playground it should be ok now.
