Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I?m having an issue to which I haven?t been able to find a solution just by searching here or on Google.

I?m building a project which is shared by multiple developers. For some reason I?m the only one with this issue. I checked out the code several times and even re-installed Xcode.

So what happens is that when I build the project the build process hangs forever. A process called ?Interface Builder Cocoa Touch Tool? runs and starts accumulating RAM until it reached the Mac?s limit (which is 16 GB). At this point, as soon as I see that I kill the process and the build fails.

On the Console App I see this:

2014-10-02 4:45:16.013 PM Interface Builder Cocoa Touch Tool[875]: BUG in libdispatch client: kevent[EVFILT_VNODE] add: "Bad file descriptor" - 0x9  2014-10-02 4:45:17.956 PM Interface Builder Cocoa Touch Tool[875]: assertion failed: 13F34: libxpc.dylib + 29453 [75E30F22-514B-3A20-B82C-EDA43AF5C35C]: 0x8d  

On Xcode I see the build getting stuck on ?Compiling 1 of 1 story board files?, or ?Compiling 1 of 1 asset catalogs?.

Even if I stop the build, the ?Interface Builder Cocoa Touch Tool? process will continue running and accumulating RAM.

I do see two warnings related to the story board:

Base.lproj/MainStoryboard.storyboard Frame for "Scroll View" will be different at run time.  Base.lproj/MainStoryboard.storyboard: warning: Unsupported Configuration: Prototype table cells must have reuse identifiers  

And I see two warnings for the assets:

../Images-2.xcassets: A 57x57 app icon is required for iPhone apps targeting releases of iOS prior to 7.0  ../Images-2.xcassets: A 57x57@2x app icon is required for iPhone apps targeting releases of iOS prior to 7.0  

But I don?t think these are the cause.

Here are Xcode?s and the Mac?s information:

2.5 Ghz, Core i7 with 16 GB of Ram. Os X 10.9.5. Xcode 6.0.1.

Any help is more than welcomed.

Thanks.

Sorry i cannot post comment because I don't have enough reputation points. But I ran into the same situation and i reverted back to using Xcode 5. Xcode 5 works perfectly for me.

I too have been having issues with storyboards causing freezes with XCode 6.0.1 on OS X 10.9.5.
I can't even start Xcode because it tries to re-open the storyboard.

Here's what I do to recover (until it happens again)

IMPORTANT: make sure you back up your storyboard file in case you accidentally delete it

1. Completely close Xcode
2. From a Terminal (or Finder): MOVE your storyboard file to a safe location
3. Restart XCode and open your workspace or project
4. In Xcode: remove the missing storyboard file from the project
5. From a Terminal (or Finder): COPY your storyboard back to its original location
6. Import the storyboard to Xcode (Add File or drag-drop from Finder)

At this point everything "usually" works for me: open the storyboard, build, run... I can keep working with the storyboard until the next time I re-open the project. Then it happens again and I have to repeat the same steps.

I too had this issue and think I have found the reason for the hanging; I removed some constraints from the storyboard and I no longer get this freeze during the build phase.

Answer by Felipe Baytelman for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

Apparently, there's a corrupted .xib file. I reverted the file that was getting stuck compiling. I'm researching what's the line that's making it crash.

EDIT

I reproduced the problem in the console: There is a serious bug ongoing here.

Answer by Felipe Baytelman for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I did a "binary search" to find which element was corrupting my .xib file.

Each time, I had to kill Xcode, delete Derived Data. Once I found the sub-view that was causing the problem, I removed and reconstructed it.

Answer by knukko for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I had the exact same problem: opening the storyboard in xcode results in beach ball with the Interface Builder task consuming all the memory. I got it back working by editing the xml of the storyboard file and setting

useAutolayout="NO"  

in the document node. Of cause this is not a solution to the problem (which seems to be a bug in xcode) because it screws all constraints, but at least I could open and compile the storyboard again.

Answer by 4mo1 for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I am not using Storyboards but I think the problem here may be at a higher level and not related to storyboards. I faced the same problem (xcode hangs while trying to build the app, activity monitor shows interface builder using 99% CPU).

The following worked for me - In the .xcodeproj file, changing the iOS Deployment Target from 6.0 to 7.0 fixed it instantly.

Answer by user2002649 for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I fixed the problem by changing the Builds For setting in the File Inspector for the storyboard from iOS6 & Later to iOS8 & Later It seems to work on iOS 7.0 & later, but changing it back to any of the iOS6 settings makes the problem recur.

Answer by MobileVet for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I had two Xcode versions installed, 5 & 6. Not sure if this was the cause, but Apple indicated this does happen with people and that the appropriate action is to ensure that the correct version is 'selected'

xcode-select -p  

Not sure this would have fixed the issue or not, but after removing both versions and then installing Xcode 6, things appear to have been resolved.

Answer by Brigitte Endres-Niggemeyer for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I am making the same bad experiences with Xcode 6, joined with some others. For instance Xcode crashes when I try to move a textfield on the IB horizontally, both by movie it on the drawing and by adding something to the x value on the inspector. I reported the bug to Apple. Sanitizing Xcode will take some time. So that I return to Xcode 5 for the moment.

Answer by Simon Tseng for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I fixed this issue by just resolved all warnings related to storyboard. For example: 1. I deleted unused prototype cell in TableView, because it will cause warning about something like "No reuse Identifier". 2. I deleted unused view controller.

Answer by Bin Zhou for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

In Xcode, right-click on the storyboard file and select Open As -> Source Code. In the source code editor, change the value of "useAutolayout" to "NO". Then, you should be able to open your storyboard as Interface Builder. I ran into this annoying issue. Now, all of my storyboard files created in Xcode 5 can be open in Xcode 6 now.

Answer by bobeast for Xcode 6: Build hangs and Interface Builder Cocoa Touch Tool starts allocating all RAM

I believe the problem is related to the new font mechanism in interface builder. Remove all references to fonts in your project and I bet the problem goes away.

Experiencing same issue here, but with Xcode 7.2.1 (7C1002), when I use the option Editor --> Export for localization...

Same asserts in the system log :(
