I am trying to implement the getting started helloWorld, on XCode 4.6, but I am getting this sigabart. The code is exactly like the apple website. No errors are produced but in runtime I have this:

I did delete the connections and connect the label, textfield and button again to view controller.m but get the same result. I connectted the textfiled to the delegate but received the same result.
Can someone help elucidate what is going on?
Check for the linking of objects or methods in your storyboard connections inspector.

So I'm loading some images from files which I saved in the app's document directory and upon completion, I update a dictionary which holds all the images for my tableview. So far so good, everything's working just fine.
But now I've stumbled upon a really peculiar crash. Sometimes when updating the dictionary the app crashes, giving me the error message: "Heap corruption detected, free list is damaged at ...".
I've added a symbolic breakpoint at malloc_error_break and turned on the Address Sanitizer the Undefined Behaviour Sanitizer and Zombie Objects as advised in this post: iOS error : Heap corruption detected, free list is damaged and Incorrect guard value: 0
Now I'm getting the following error message, which doesn't really help me either:

I have no clue as to what could've caused that crash, hopefully someone can help me out here!

I have tried detecting Zombies using Instruments but of no use.
and after the application crashes there is not trace of any Zombie in the Instruments.
What else should be done to detect the reasons of the crash?
Something is doing a setValue:<some object> forKey:#"gridView" - probably Interface Builder has a view set to that, but that property is no longer in your .m file.
Failing that, do a global search on your project and find all occurrences of gridView, and add an assert in front of each that the object receiving that message has a property gridView.

Myxcode version 4.6.2 please help.
There's no method called imei on the UIDevice class as provided by Apple, so when you try to call it you get a crash.
That said, there is such a method in Erica Sadun's UIDevice extensions - perhaps you're reusing code that assumes that they're present - so if you add them to your project then your code should work as you expect.
When I follow this tutorial, it gives me an error on the [playercontroller release]; line, so I remove it, and then it gives me these errors when I try to run it.
I tried making another app to test the video, and it works seamlessly, but it will not work in my main app. Can anyone help?
And when I reimported the framework, and tried to play the video, it gives me this error:

I take it GVE1ViewController is a class you wrote yourself? Does it definitely implement a method called GrommeVideoExcerpt1? Is what you assigned to the variable actually an instance of GVE1ViewController (or a subclass?) Put in an NSLog to check that it really is an instance of GVE1ViewController.
To do the NSLog, you need a line of the form:
NSLog(#" My controller = %#", myVar);
where myVar is whatever variable you have containing a reference to the GVE1ViewController.

i´m very new to xcode... a made an app (simple calculator) work´s pretty good (on simulator and device).
When i set the main interface in the summary options from Target, i get the following error when starting the simulator:

is there a solution for the problem?
If you have a control in your nib (xib file) that is linked to a property (IBOutlet) or method (IBAction) in your view controller, and you have either deleted or renamed the property or method, the runtime can't find it because it has been renamed and therefore crashes.
In your case, you have set the Main Interface property of the project to your ViewController.nib. This is a problem because the only nibs that should be used as Main Interface should have UIWindows in them and the File Owner in that nib should be set to the AppDelegate. The UIWindow in the nib should be linked to the File Owner's (AppDelegate) window property. Because you set that with a nib without the traits the runtime was looking for, it gives you this error.
The solution is to leave the Main Interface blank as you do not have to set up UIWindows manually anymore.
Just had the same problem and fixed it by right Control-Clicking controls in the xib file to see referencing Outlets. Turned-out that some of the control were still referencing and older name and causing this error to happen.
if you get a message similar to:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason:
'[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key
click the add (+) at the left bottom corner of the BreakPoint navigation area, choose 'add Exception Breakpoint', since it is crashing because of 'NSUnknownKeyException', and opt for 'All'. Run the program. The program stops at the first exception.
try this, select File's Owner then click on the "Connection Inspector" (upper on the top of right pane), you will see all the outlets. Look for any sign like this (!) you will find it on the small circle which indicates a missing outlet, all you have to do is linking it properly or remove the outlet.
Try this,
Go to Target=>Build Phases=>Compile Sources
Then include 'calculatorScreen.m'
I was facing the same problem. In my case i had renamed the text label in .h file. So there was multiple reference for that label in my main.storyboard file. Once i removed old reference my code started working.
