We have a UITableView object in our storyboard that is assigned to a custom class. When I load the view and try to select a row, the application crashes. I've been putting breakpoints up and down my class—the most intuitive one being at didSelectRowAtIndexPath—but all of this is to no avail. App just crashes before I get to any of my breakpoints.
This bug only exists in iOS8. Runs fine in iOS7. Any ideas what is causing this? Below is a log of my console.

Okay, fixed the problem. Had some bad CONTRL+drag connections between my Storyboard objects and my IBOutlets. Turned those off and now the problem is gone.

libc++abi.dylib: terminating with uncaught exception of type NSException
You have an outlet that doesn't exists anymore. Check the connections inspector for lost connections.
Your error is Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key docPassword.
Usually this means that the .xib file (or storyboard) for your viewController contains an outlet (docPassword in your case) that isn't in your code. You should either add the property in your code or remove the outlet entirely in interface builder.
I am working on a Swift project in Xcode v6.1.1, and I am getting the following error that I don't understand. I believe there is a problem with a couple of the Labels in my Main.storyboard and/or the UILabel variable I have them connected to.
I have tried everything I can find to fix it, and nothing has worked.
Any help would be appreciated.

Have you forgot a : in the string name?
Is your class marked with #objc?
Just by looking at -[UILabel longValue]: unrecognized selector sent to instance 0x7b8e1810 gives me the answer. You are treating a UILabel as an NSString.
Somewhere in your code you have [label longValue] where you mean to have [label.text longValue].
After looking at more of your call stack. I can see that it's happening while a while initializing a view controller from a storyboard.
Have you subclassed any views? It looks like you might have inadvertently changed the type of a property from NSString to UILabel.
So... I fixed the problem. Turned out the answer was right in front of me the whole time (it usually is). The Label that couldn't be initialized had the same name as an Int variable I had declared in the same class, only with the first letter capitalized. For some reason, I assumed it was case-sensitive, so that wouldn't matter...
I am experiencing unrecognized selector for this:
-[NSNull _isCString]: unrecognized selector sent to instance
The given log crashes my app. What are the possible causes of this error? Can anyone give some ideas? Any response will be very much appreciated. Thank you very much!
Actually, I just want to edit a row from a table view controller. I have noticed that when I click the EDIT at the navigation bar of my table view controller, the rows 0, 2 and 4 gets the error but the rows 1 and 3 doesn't.

NSNull is a class that class does not implement _isCString, hence the unrecognized selector error. Objective-C usually uses nil to represent a 0 or a null pointer value. However, standard containers like NSDictionary and NSArray cannot hold nil values, so you occasionally see [NSNull null] used instead.
It's basically convention in your code that determines whether you check for myVal == [NSNull null] or myVal == nil.
Based on the trace you posted, it appears you need to do a myVal == [NSNull null] check somewhere.
I'm trying to develop a Mapkit app. There is a map, a lot of annotations located on this map. If I touch one of these annotations my app is displaying a custom popover from a storyboard. If I touch another location on view while popover is active, popover disappears without any problem.
But, if I touch one of annotation and move my finger out of annotation without releasing my finger, I got the error.

It is quite late with this Answer, but for those looking for a solution: Try to create a storong property to hold this popover, and then when taping on the map accessory use the self.popover reference to init it with a content.
I have an app called "FirstAid" that crashes in the simulator and on a device. If I create a clean project called "FirstAid" that also crashes with the same report. Any other named app is fine.
I have done a clean, and rebuilt it but it still crashes.
How do I fix it?
