Now I am developing SWIFT Application using XCode 6.1.

Previously I was using XCode 6.0.1 instead, but because of some reasons, I upgrade XCode 6.1.

But unfortunately, I could't type the codes in XCode 6.1 because of slow speed on XCode Code Editor.

It writes the one letter a second.

To be strange, when I work on Objective-C project on same XCode6.1, there is no problem, and all are working well.

But only for swift project, this issue occurs,

When I remove all data from DerivedData folder, this issue disappears but after 1 min, occurs again.

What's wrong? What can I do?

If you have an any idea, please let me know.

Thanks in advance.

  • Can u let XCode for a while for indexing the project. May be this kind of background processes effects your case – qwerty Nov 30 '14 at 01:43
  • I keep XCode for indexing and after completion, issue occurs again. The problem is that XCode does always indexing while typing every letter. – Zheng Guang Nov 30 '14 at 01:46
  • How much is your RAM? If low, I suggest you to install more RAMs. I also have experienced Xcode is slow on low RAM macs. – Jun Nov 30 '14 at 04:58

On Xcode 6 make sure you are running Yosemite

  • Try re-installing xcode 6.1

  • Try restarting your entire system

  • Your RAM might be low for some reason, and this could definitely be the cause. Get Memory Clean from the app store to free up some RAM

  • Create an entirely new swift project and delete the old one and see if the issue persists

Hopefully one of these options solved your problem!

    I don't know why I got the downvote because some of this could actually solve the problem. I would think it would run better on Yosemite because I am running it on Yosemite with no problems. Also, when upgrading to Yosemite, Xcode 6 is automatically installed. – 24GHz Nov 30 '14 at 03:20
  • Also, I don't think indexing is the problem because it shouldn't lag up your system like that. I have a 2 year old macbook pro and it does not lag at all at the indexing. – 24GHz Nov 30 '14 at 03:23
