I have implemented custom segue and custom unwind segue in a sample app using swift. custom segue is working properly but custom unwind segue give the following error:

Could anyone help me understand why Im getting this error? It seems to be happening when I load one of my view controllers but I can't see why.
What usually causes an error like this?

You most likely have an Outlet assigned to an element on the view controller you are transitioning to that is no longer connected to your code. This youtube video explains it in more detail.
To hunt down this issue, try right-clicking on all your elements (UILabels, UIViews, UIButton...) with the assistant editor open and cross check to see if the outlet name is referenced in the view controller.
I am using the following code:
#IBAction func popToRoot(sender:UIBarButtonItem){
navigationController.popToViewController(foodforteethViewController(), animated: false)
}
This function is linked with a custom back button and the h file is linked in the objective-c/swift bridging file. The issue with this is that I get an error as below:
2014-07-19 23:35:40.842 FoodForTeeth[9040:238499] * Assertion failure in -[UINavigationController popToViewController:transition:], /SourceCache/UIKit_Sim/UIKit-3232.3/UINavigationController.m:5345

What's going wrong?
you can not pop a view controller which is not in NavigationController stack.You should pop like this
if you want pop to rootViewController than there is direct method use this
#IBAction func popToRoot(sender:UIBarButtonItem){
self.navigationController.popToRootViewControllerAnimated(false)
}
Another way to go back to a specific view controller would be to use unwind segues:
What are Unwind segues for and how do you use them?
I am having a strange problem in xcode. i created a button in xib and connected to a function. I am printing the message inside the function. That's all, when i click the button i get the following error. I tried clean and deleted app from my simulator.
-(IBAction)languageSelection:(id)sender is my function name

this is perhaps you are trying to call a method languageSelection with object that is infact string, but you have passed into another object which has languageSelection method.
this is because you think the object is what you want but the pointer passed the allocated memory to string and hence it will work as string. when you try to call method it crashes because it didn't find the method in string. check your object type just before u use it anywhere

see if the IBAction of the buttons are connected properly. I guess they are not properly connected
It would be much helpful if you post your source code rather than error out come.
Anyway i think you are trying to call an instance method through class reference.
The problem is here:
[Protoype_Test1ViewController saveImage]
It should be:
[protoype_Test1ViewController saveImage]
This is a common mistake when relay much on auto complete.
I downloaded the OHGridView hoping that it was the answer to all my problems.
https://github.com/AliSoftware/OHGridView
I did all that it said to do (add the class files, add the code, and change a few other things).
I went to build it and it crashed. I realized the lines of code why it was crashing:
((OHGridView *)self.view).rowHeight = 100;
((OHGridView *)self.view).columnsCount = 2;
Error from Console:

I did a clone of the repository just now and then did a build and run of his example project without making any changes to the code. It ran without any warnings or errors.
You'll need to check your code wherever you made changes.
update after your comment
Unrecognized Selector often means that you have a capitalization error or that your code isn't the kind of object that you think it is.
For example: I can get almost the same error that you get if I try to call the setRowHeight: directly against a OHGridView object instead of the view property of the object, like this
((OHGridView*)self).rowHeight = 100;
((OHGridView*)self).columnsCount = 2;
So, I would check your code to make sure that your object is an OHGridView and that you are setting the rowHeight property of the view of the OHGridView.
