For some reason whenever I add a text field to my project and try type in it, the app crashes.
The errors I get are:
Can't find keyplane that supports type 4 for keyboard iPhone-PortraitChoco-NumberPad; using 1336863583_PortraitChoco_iPhone-Simple-Pad_Default
-[NSNull length]: unrecognized selector sent to instance 0x1018b1d80
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull length]: unrecognized selector sent to instance 0x1018b1d80'
This happens in both the simulator and on device. I have unchecked "Connect Hardware Keyboard" in the simulator settings also.
Do I have to handle each and every input?
So I saw a solution deep in a forum, and it did actually solve the issue.
For some reason the tab bar controller I was using was causing the issue. Simply deleting the controller, and then going Editor > Embed In > Tab Bar Controller and re adding the views fixed it.

I don't have any code implemented in view controller to set the font or attributedLabel. But I'm seeing crash with below reason.
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: -[_SwiftValue pointSize]: unrecognized selector sent to instance 0x610001040ba0
There is another way of debugging issue. When app is crashed, check left panel and you will observe threads stack. In that find out Obj_exception_throw select that and use your logging area to run command po $arg1. This may give you the correct reason for crashing.
Or else, you can try using Application Unit tests for verifying all your IBOutlets and objects, loaded from NIBs.
You can select that xib and open it as source code.
Or search tho whole project to find that.
When our iOS application is compiled on iOS 10 Developer Preview SDK, when launching one of the first view controllers of the application, the application crashes with this exception :
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIDeviceRGBColor countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0x17adb5a0'

libc++abi.dylib: terminating with uncaught exception of type NSException
In the code of our application, this selector of UIDeviceRGBColor is never called.
Does someone have the same problem ? Is it a bug of iOS 10 Beta ?
When compiled with iOS 10 Beta SDK, the problem occurs as well on devices running on iOS 10 Beta as on iOS 9.
The problem does not appear (not on iOS 10, not on iOS 9) when the application is compiled with iOS 9 SDK
Thank you.
Best regards.
In case your are using interface files like Xib and Nib for your views, refer to my answer in this question
Quoted from that question:
When I try to compile and run my project with the same configuration (XCode 8 beta 6, iOS 10 SDK), I encountered a similar issue, except that my error message was:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIDeviceRGBColor length]: unrecognized selector sent to instance 0x600000479280'
And I noticed that this issue only occurs when the view is init by using interface files, i.e. Xib and Nib. I solved this issue by:
Open your interface file, in the right panel, navigate to the File Inspector tab.
Change the attribute highlighted to "iOS 7.0 and Later" (or whatever iOS version later)
Then compile and run your project again, this should fix your issue, though I am not sure about the reason behind this.
I accidentally deleted View Controller in Main.Storyboard and now I am trying to build and run my game and it says build "Sussess" but it builds Lanch Image Appears and then the screen is white and nothing happens please help me. My game is in appStore already I cant remake it!!!! What should I do?

I think usually, the file gets deleted from the project but is usually present in the project folder. Check if your view controller is present in the Project folder. If it is present, you can add to your project again.
I have implemented the AdWhirl to show different network Ads but while it shows the ads on my view and I tap to open the ad it crashes with the following displayed in the log
-[AdWhirlAdapterIAd helperNotifyDelegateOfFullScreenModal]: unrecognized selector sent to instance 0x9fce850 2012-12-08

I searched too much but couldn't find solution. Give me suggestion to remove this error.
Thanks in advance
Are you sure that the AdWhirlAdNetworkAdapter+Helpers.h file is included in your project? Make sure everything under AdWhirl/Internal is correctly referenced in your build settings.
you are not having helperNotifyDelegateOfFullScreenModal method in your File. Check that one because the name says, its delegate method. you might forgot to implement that method
I'm getting a strange exception in Xcode 4.2.1 (ARC-enabled project) that I can't track down to the root of the problem.
This is what the exception looks like:
2012-03-18 22:19:32.855 Project[14225:707] +[UIPickerTableViewTitledCell isEqualToString:]: unrecognized selector sent to class 0x3f2bbec4
2012-03-18 22:19:32.859 Project[14225:707] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[UIPickerTableViewTitledCell isEqualToString:]: unrecognized selector sent to class 0x3f2bbec4'
What is a UIPickerTableViewTitledCell? I suppose it is some internal class for the UIPickerView to use. But I'm not referencing that class anywhere in my project.
My application is setup as a Tab Bar application with a navigation controller in each tab and this particular tab has a tableview and pickerview.
It sounds like you have an over-released object. I get that when in pre-ARC code, release is called one too many times. The code sounds like it is looking for an NSString to send isEqualToString: to but instead of getting the NSString which has been released already, it gets this random instance of UIPickerTableViewTitledCell.
I would enable Zombies. In Xcode 4.2.1, you can find it in the menu item Product > Edit Scheme. Go to the Diagnostics tab. Then there is an Enable Zombie Objects checkbox. This will make your over-released object into a Zombie, so you can figure out exactly what object is causing your crash.
I would read the Apple doc Technical Note TN2239: iOS Debugging Magic for more in-depth information on this. The whole doc is great, but you can start off by reading the sections titled "Zombies!" and "More Zombies!"
