Xcode error

I just started to learn how to code with "Intro to App Development With Swift" from Apple on iBooks and whenever I try to edit one of the given practice files, a window pops up saying "The document “02_Naming.playground” could not be saved. The file has been changed by another application. Click Save Anyway to keep your changes and save the changes made by the other application as a version, or click Revert to keep the changes from the other application and save your changes as a version. You can also click Save As to save your changes to a different file." This error pops up every time I type a keystroke in the file. How do I fix this?

Happens to me on HighSierra beta1 in both xcode 8.3 and xcode 9.0 beta1. Makes playgrounds unusable 😟

(this is MatthewAro) Thanks! I was not sure if it was a beta issue or simply an Xcode issue I was unaware with. Still not fixed in Beta 2 btw

Im getting the exact same issue. I've been searching the internet for the fix for a couple of days now. Im thinking this issue has something to do with the beta version of the operating system. Lets try to stay up to date on this fix.

I had the issue, but when I removed the playground files out of Google Drive and into Documents that seemed to fix the issue.

Not fixed yet on High Sierra Public Beta 7. But I fixed myself moving the folder into a USB.

I was able to fix this. I am on macOS High Sierra 17A362a (GM candidate I guess) and was getting these issues. I updated to Xcode beta 9.0 9A235 and the issue seems to have resolved itself.


Phew! It was incredibly annoying!

I am still receiving this message on a frequent basis. I am running xcode 9.1

I never saw it before xcode 9. Does anyone have any suggestions?

thanks

I use Xcode 14 and I have this issue. But not when working in Playgrounds, just when editing a SwiftUI view file.
