Installed Mountain Lion and Xcode5. Tried to open a project recently developed for iOS6. And now xcode is dramatically slow. Any ideas whats wrong with him now?
EDIT
It works fast with new projects I create. It slows down only when I open the old projects.
Ok. I found the problem. The screen attached.
When I switch 'Opens in' to Default 5, Xcode changes the UI Presentations to ugly iOS7 design and xcode suddenly starts work fast like in good old times. Switching back to 4.5 brings the very slow performance back. Thats it guys!
It reminds a problem I had with xcode 5 ( also mountain lion), the typing was very slow..
what help to fix this was removing all breakpoints ( I had nice and big list of breakpoints)
It seems to be keeping previous windows open too, so the more you switch between source files or XIB's, the more it will lag. I didn't check the memory use, but maybe it's running me out of RAM since I have a limited amount free with my Windows VM running. Quite annoying, but it works for me to close and reopen Xcode when this starts happening.

For Past 4 week i observer when i run my Xcode application on simulator on first time simulator launch it consume around 500MB internet data.
This is not project specific issue. Every time when i shutdown and start the mac and run Xcode as soon as simulator open it will consume same amount of Data.
Can any one help me What is the issue?? or any background service run??
Xcode version: 11.6 (11E708)

Please help me unnecessary every time my Internet Data is consume i have to fix this
This issue is still persist after updating to xcode 11.7
Thanks For #Rado for suggesting the https://apple.stackexchange.com/.
After posting the question on https://apple.stackexchange.com/ i fond the answer.
Orginal Answer: Xcode simulator constantly download something
Answer:
rename the file com.apple.nsurlsessiond(Dont delete) in
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/UserEventPlugins/com.apple.nsurlsessiond.plugin/
to something -com.apple.nsurlsessiond
and also the file nsurlsessiond(Dont delete) in
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/libexec/
to something -nsurlsessiond
Apps with admob works perfectly also no problem with safari
If you don't need an internet connection for testing you application, you could simply disable the network.
You could run wireshark and see what it is actually doing, or at least see where it is connecting to.
I used tripmode firewall don't give simulator internet access only give when you need it.
Works fine but when you forget to turn it off and start the simulator next time, you feel horrible :(
Since upgrading to xcode 7 and greater, the performance of xcode is terrible. When I click on a class or scroll the code pane it sometimes takes up to 30 seconds before reacting and often I need to force quit xcode and restart.
I have turned off source control and I am not using swift.
I have a new macbook pro with 8gb memory and an SSD. my computer is fast and has no other performance issues.
-UPDATE-
I have cleared derived data and am not using any unusual plugins
Does anyone know what may be the problem? I imagine some build setting is causing this but im not sure which.
The issue is totally with xcode 7.
try to commit/save every time you make some changes, it will increase some performance
I'm working on a big project and I have some serious problems with Xcode RAM management. In the informative app I'm working on I have over 90 UIVIewControllers on my storyboard. Once I open my project and go to my storyboard file (just changing labels, zooming in and out etc') it takes less than 2 minutes for Xcode to go from 400MB usage to 8 gigs.
This will only happen while I'm using the storyboard.
This never happened to me in other apps I've managed so I believe it got something to do with the size of this app.
The above was on a new MacBook Pro. To test things out I tested it on a Mac Pro with 16 gigs of RAM. First run, same issue. 16 Gigs of ram is used after less than 2 minutes.
Things I've tried:
Deleting DerivedData (the issue is on 2 different machines so it can't be it but tried it anyway)
Deleting project.xcworkspace
Read about stoping indexing BUT without autocomplete and quick help I'll have nothing to compile anyway
I'm using Xcode 4.6.3
sounds like it is a problem with that version of Xcode. I am using 4.6.3, and have never experienced this, (although the apps I work on are never that big). You should definitely try Xcode 5, even if you cant submit to the appstore, at least you'll be able to work on your app. Then you MIGHT be able to open it in version 4.6.3, and submit it from there, not quite sure it will work, but its worth a shot. Make sure you keep a copy of what you have so far incase your Xcode 5 version wont work in 4.6.3, so you dont loose your work. hope this helps.
My Xcode version is 4.6.2, which is the latest at this moment 2013.6.2, when I try to run a project(not a specified one) in simulator, it randomly freezes(stops) at indexing. I don't know if it's my macbook's problem because it's relatively a old one. My project is very light-weighted, just some demo. I'm a newbie. Normally, it works well, but sometimes it freezes at indexing, say 5% possibility.
And I cannot stop it even I clicked the "Stop" button at the right of "Run", and either if I close the simulator. I have to force the computer to shut down by keep pressing the power button. It brings damage to computer.
Anyone knows how to fix this? Or I have to get a newer one? Any help will be appreciated. THANKS.
Screenshot:
Xcode 4.6.2 in 1.4GHz, 2GB Ram
This is the main problem, the Xcode needs 2GB+ itself, and there are others applications and processes running in foreground and background.
I have 3GHz C2D, 4GB RAM, still at times it hangs at times :(
So, either you need to upgrade the hardware or degrade the Xcode version.
EDIT:
As you have Macbook air, you cant upgrade the RAM which is soldered to the motherboard.
I recently updated my MacBook Pro (2.3 GHz Intel Core i5) from Lion to Mountain Lion and simultaneously upgraded Xcode to the latest 4.5 version. I've experienced one very irritating problem. While programming I'm used to have a couple of tabs opened at a time. Ever since I updated, each time I switch tabs, Xcode freezes up for a bit (a couple of seconds). Does anyone have a suggestion to solve this problem?
I followed a tip on deleting project.xcworkspace to improve performance. Which seamed to help, but only for a short period of time.
It's a common issue and was fixed in XCode 4.5.1.

If you have multiple partitions (maybe a backup of Lion was kept) ensure that xcode really comes from the Mountain Lion partition.
The App Store App update for Xcode seems to take the first Xcode.app it finds and will apply any update to that version. In my case it updated the (inactive) Lion partition, even so I booted from the ML partition.
xcode-select did not complain when I tried to change it to the ML version.
So I ended up doing the great housekeeping:
do a chmod 000 /Volume/<old Lion partition>/Applications/Xcode.app
installed a fresh copy on Xcode.app into /Applications
verify the destination of the dock icon (must point to the ML Xcode.app)
My Xcode is now fast as before and it remains fast. You can get the Xcode dmg and the command line tools from https://developer.apple.com/downloads/index.action. I don't think there is a difference in the binaries, but with the DMG I could see where I dropped the Xcode.app.
I found your question before I discovered a partial solution.
As of today, I find XCode 4.6.1 GUI dog slow for my taste, specially considering that I run on a one year old mac, SSD, compile to a 2GB RAM disk and still have 6GB RAM left. Even Eclipse runs lightning fast compared to XCode
4.5.1 did improve something, but after a long time using XCode I do not have any hope for some of its problems being solved ever.
That being said, I have noticed that "Live issues", the main tool bar and all the panels slow down tab switching to same degree. The biggest offender so far are the navigator panels.
Once I got used to a minimalistic Xcode window, layout some specific task tabs, keep a separate window for xibs and learned the shortcuts to enable/disable the panels, I no longer suffer so much with XCode responsiveness, but there is still some lag that can be clearly felt.
Check that there is not heavy coding on ViewWillDisappear.
Also if you have NSURLConnection or any other having delegate methods should not get called while switching tabs.
