Error Xcode 6 --> Error SourceKit terminated. Editor functionality temporarily limited

Question

Sometimes I get this error in Xcode 6 and the canvas turns white.

enter image description here Am I the only one this happens to, or is it a bug?

report a bug with Apple... and otherwise, expect anything but a working software from beta software that early in its development stage. — Volker, Jun 05 '14 at 15:05
You're right, Xcode 6 has just been released in beta. Anyway, I will report this problem to Apple — dpbataller, Jun 07 '14 at 00:09
got the same thing by using `override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!)` instead of this `override func touchesBegan(touches: NSSet, withEvent event: UIEvent)`. — Vaseltior, Jun 07 '14 at 17:19

I still have this issue.

I have a working solution:

If you are targeting on iOS8, switch the deployment target to iOS7,

If this issue happen again, switch the deployment target to iOS8,

If this issue happen again, switch the deployment target to iOS7,

If this issue happen again, switch the deployment target to iOS8,

...

Hope this help you.

Update:

Seems this is better solution:

Quite Xcode, and delete all the folders in the DerivedData directory

would appreciate if you are specific and point exactly where is the derived data directory. – Ankish Jain Dec 02 '14 at 05:49
A better "better solution" would be to provide a specific path to the DerivedData while you're in the business of trying to help people, since you already have the context and we don't. – clearlight Feb 06 '15 at 15:24

I use Xcode 6 beta5, when I declare member as lazy, it will show this error when I enter new line. It works when I remove the keyword lazy.

class PointZoomingView : ZYZoomingView, CMPopTipViewDelegate
{
    private ***lazy*** var pointButtonList: [PointButton] = []

    var hwRate: Double! = 1

[UPDATE] If your [PROJECT_NAME]-Bridging-Header.h import a non existing header file, the SourceKitService will be Terminated frequently

SourceKit appears to simply be very, very bad.

The list of problems above contains a number of possible causes; beta software, code being updated across releases (created in one version, edited in another), problems with IB connections, bridging or issues with override and/or lazy.

Well I'm using the release version of Xcode 6.1. The code was created in this version. There isn't a single use of overrides, lazy or bridging. It does file handling, and doesn't have a single IB connection (yet). The code is entirely devoted to opening text files and parsing them, using the most basic Cocoa primitives, mostly NSString.

SourceKit crashes every couple of minutes. It crashes so often and randomly I cannot determine any sort of pattern. One issue appears to be if an existing line of code contains a reference to one type and then changes to another, but that's definitely not sure-fire nor the only cause. (Update: crashes with every 10th or so keystroke now)

I write in Sublime Text 3 and only compile in Xcode now... The experience just like coming back to 1980s and using only keyword highlightable Turbo C. – WeZZard Oct 31 '14 at 01:52
Latest Xcode, brand new 15" macbook, constant crashes. It's pretty miserable. I should probably just switch to sublime for all coding too :( – nflacco Nov 04 '14 at 20:28
I found some solace in re-downloading the entire 5.2 GB Xcode from the dev page. This appears to be an *older* version that what I had, which may be in error. Nevertheless, the number of crashes declined to about 1 every 5 minutes. Sadly, the time taken to crash increased. – Maury Markowitz Nov 05 '14 at 14:34

I was having a problem with xcode 6 beta 6. I finally changed the iOS Deployment Target from 7.0 to 7.1 and my problem went away!

You should report a bug to apple as Xcode is in beta mode so don't expect it to work fine. Although there are many points at which this occurs in my case it was occurring randomly or by writing piece of code in between []. Download the latest version of Xcode 6 beta and enjoy coding...

unfortunatelly this does NOT fix the problems with ObjC – hris.to Jan 05 '15 at 08:38

Nor Swift. It does reduce them slightly, it now crashes every 10 minutes rather than 5. – Maury Markowitz Feb 16 '15 at 18:42

Try rewriting the methods you have defined/overrided.

I faced this problem when I updated my Xcode6 from beta 3 to beta 4. Xcode6 beta 4 differs in the IBOutlet declaration and treats IBOutlet declarations of Xcode6 beta 3 as errors. When I changed the declarations(of Xcode beta3) with beta 4 this SourceKit Service error popped up.

What I did to fix my code :-

Removed all the methods of tableview delegate and datasource and write them again. Now everything works just fine.

I can confirm that this command on terminal solves it

rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache

I can confirm it does not. At least not on my machine. – Maury Markowitz Nov 22 '14 at 18:02
Close XCode, run this command and reopen XCode. – D.A.H Nov 23 '14 at 02:50
Indeed, this solves it! – Youssef Moawad Nov 23 '14 at 08:44

I did, and it worked for about 10 minutes and came back again. – Maury Markowitz Nov 24 '14 at 12:09
Maury Markowitz, probably your issue is based on some another reasons. Might me related to somme project settings, coding, importing etc related elements. You have to dig deeper on this case, to eliminate actual cause reasons. – D.A.H Nov 24 '14 at 12:26
Trust me, I've done it all. Cleared this and many other caches, re-installed fresh, etc. As I said in the answer above this, SourceKit is simply filled with bugs, and the solution that works for one person will simply expose another for someone else. – Maury Markowitz Nov 24 '14 at 15:52

.. delete all the Content of the DerivedData folder .. apparently there are project based files and moduleCache may be a general one, and by deleting only the moduleCache the problem can still remain in the project based files
