I'm developing a new app but I've a little issue with Interface Builder...
I've installed Xcode 3.2.3 and iPhone SDK 4.0 GM.
When I create a new Tab Bar Application project in Xcode, opening the MainWindow.xib file in IB, the Tab Bar Controller won't open... I tried reclicking it but nothing!
I also uninstalled and reinstalled all developer tools but without any results...
Finally if I try to build and run the project in the simulator, the tab bar controller shows normally!
Can anyone help me? :)
It sounds like something similar to what I have experienced with my projects and the new sdk. Some of my IB files such as ones that contain UIViews when double clicking on them they refuse to open.
I haven't had to reinstall or nothing usually quitting IB and xcode and restarting helps I can't remember if I have done anything else to fix it. It may be an issue with the new 3.2.3 xcode as I don't recall having anything like this happen in my 3.2.2 build.
If it becomes a large problem for you have you considered removing the tab bar and rebuilding it? Just a thought. It may be troublesome to do so but if it fixes it and allows you to continue coding your project it would be worth it.
You said in your question that you're running iPhone SDK 3.2.3 with iOS4 GM. You should update your SDK, as the SDK is now at version 4.0 officially.
Otherwise, it sounds like your Xcode installation is somehow corrupted in some way. You may need a complete reinstall.

In xcode, I tried to add a tap gesture to my app and when I built it, it started a problem with Xcode. It goes from building, 'running on iPhone 6.1 simulator' to 'finished running on iPhone 6.1 simulator'.
If the simulator is closed, it starts up with a black screen and you cannot click the home button etc. If open, nothing happens, the app doesn't install but the simulator doesn't crash.
I have tried the armv6 architecture 'fix' but that didn't work. I have also cleaned the project and project data. I have reset the simulator multiple times as well.
If I add the old files to my new project, it works up to a point (I copy and paste old files into new) but then the same happens.
Thanks for your help in advance!
NOTE:
New blank projects build and run fine.
EDIT: It still didn't work after undoing my previous actions, and the simulator is responding according to Finder, although the screen stays black

UPDATE
I had a folder named 'resources' in my application, imported as a reference which, following links from the thread #arthan.v supplied me with fixed the problem. What I did was rename the folder to files and reimport it.
Thank you so much, I spent 2 days trying to fix it before now!
Click the Center Button in View on your right hand side of Xcode.
In your Bottom bar, you'll see error: failed to attach to process ID 0.
Check these error: failed to attach to process ID 0 and Xcode compiles my App, but can't run it in the simulator
This sometimes gets fixed by these steps:
iOS Simulator > Reset Content and Settings ... > Reset
Xcode > Build and Run
I experienced the same issue after I had re-organized some code and renamed the workspace and project. Eventually realized there was an old version of my test app on the simulator's homescreen. I delete that and then everything was building fine again.
You might need to add the device to the provisioning profile. I experienced this on Xcode 6 and a real device.
I was using using Xcode 4.5 to create an iPad application yesterday and completed it. But today when I took that same Xcode project and tried to run it on an older machine running Xcode 4.2, it is giving me an error about IBNSLayoutConstraint. Which i guess was due to the new features that were included in the new Xcode 4.5. So I was thinking is there a way to open project from new Xcode in the older version without having to install a new Xcode and OSX.
I am not sure if this question is asked here yet or not, but i tried to find a solution but no luck in that either.
PS. I already know that the best solution is to not opent those projects in older version but that is not what i am looking for.
There is an option in the inspector window when you select the xib file that will not use the constrains under "Show file the inspector" in the inspector called "Use autolayout".
Here is a screen shot of it.
uncheck autolayout feature from each xib file the open your project on xcode4.2, it works on my case, as autolayout is only available in iOS6
Lately when I have been deploying any iOS application to the simulator (iPad or iPhone), XCode locks up (Not Responding) and the simulator simply displays a black screen. I have to force quit both.
Steps I have taken so far towards a resolution:
Clean
Reset the Simulator
Deleted the simulator folder
Reinstalled XCode from the App Store
Reinstalled XCode from the developer center
Has anyone else encountered this? Any suggestions for a solution?
Other info:
OSX Lion 10.7.3
XCode 4.3.2

Thanks in advance for any help.
I had this problem and was able to continue by:
1) Edit the run scheme by clicking on the first part of the App name to the right of the "Stop" button to bring down the scheme list and click "Edit Scheme..."
2) Click on the Run item and change the debugger from LLDB to GDB.
3) Run
I think the problem was that I validated the settings and it offered to automatically change the debugger from GDB and LLDB and I clicked "OK" because the advisor message sounded very self-assured.
Enjoy.
Under Scheme, go to edit scheme, and change launch from wait for App.app to launch to automatically under the Info tab.
EDIT: If you upgraded Xcode, make sure the old separate simulator is uninstalled.
hmmm, weird simulator, instruments issue i had once would work when i command-tabbed back and forth. try deleting derived data?
hopeing for some help on this one
Hi set my icons up in xcode for using the neat drag and drop feature. A week later i made amendments to my icons. Drag and dropped the new amended items in deleting the older versions. The new versions show up on in the summary drag and drop section and in my project files yet when I build and run it is still showing the older versions even though i have deleted them.
Hope someone can help me out in this one. Not sure if it makes a difference, but im building the app to the simulator.
Thanks in advance for any tips on this one.
Cheers,
Laff
Open your iPhone simulator and select 'Reset Content and Settings' and try running your application on simulator.
Clean (also delete the build folder on disk) and rebuild the project. Also Delete the app from simulator. This way you make sure nothing stale got stuck.
I created a blank NavBar project and only touched a couple lines or so on one of the view controllers. I tested it fine in the 4.3 iPad and iPhone emulator but can't make it work for 4.2 at all. I get an error saying:
The selected run destination is not valid for this action.
This is what I have on my project settings:
Usually in XCode 3 that was all I needed to change but I guess I'm missing some setting in XCode 4.
What could this be?
#pokstad, you are right. I was looking at the wrong place indeed!
Choosing the target and changing the SDk there did the trick.
Thanks!
I really had troubles with this and none of the hints helped.
Finally I got an error message that pointed to an old file in the build folder, in the end a simple clean did resolve my issues (shift+cmd+K). It compiled fine. So remember to clean your current build after you changed the build settings in Xcode4.
This may be obvious, but at that moment it wasn't obvious to me.
