I've tried all the solution, though I think it's related to segue.
this is the message for the error:
UserLoginAndRegistration[34910:1717023] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'LoginView''
The error message has no segue with identifier 'LoginView' is pretty clear.
Make sure that
A segue is designed in Interface Builder for the Receiver controller and
LoginView is written into the Identifier field of the segue.

Setting up firebase auth and the app keeps crashing once the Sign Up button is tapped, I have the button linked to #IBAction for firebase signup and all classes are correct for each view controller (login and signup), I also have the correct #IBOutlets for the text fields.
2019-03-03 18:50:06.225729+0000 Spring[40363:3684981] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Spring.registerView loginViewControllerButton:]: unrecognized selector sent to instance 0x7f7f39407ec0'
For anyone else experiencing this issue, I resolved it by checking for any extra outlets on my UIButton where I had two that weren't necessary, removing these solved the issue for me.
After googling I found this page helped with my issue:
Solution
I have an XIB that I present as a modal view. I have a button that calls the following -
(IBAction)dismissVC:(id)sender {
[self.parentViewController dismissModalViewControllerAnimated: YES];
}
When I press it the app crashes with this notice -
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ViewController dismissVC:]: unrecognized selector sent to instance 0x8379350'
The thing I noticed is that I have a ViewController.xib file and I have this MapView.xib that is a modal VC I want to dismiss. It's presented from a ViewController.xib
What could be the possible issue? I've hooked up all the actions and the File Onwer thing as well.
Thanks in advance!
Try this:
unrecognized selector sent to instance
that might be your solution.
I'm trying to make a gesture recognizer in my app with Interface Builder.
I drag and drop my gesture on my view (it is a UIView which contains UILabel, UIImage and UITextView, all made in Interface Builder).
But when I compile and run, my app crashes and I get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString setView:]: unrecognized selector sent to instance 0x80a5fd0'
I don't understand the reason.
Can someone help me?
I have a Tab Bar application with four new headers, implementation and interface files, and added those as the sources in IB. They were in this format: FirstView.h/m/xib, SecondView.h/m/xib.
I then had files for First-, Second-, Third- and FourthView.
There was also a file there called FirstViewController. I did not touch this, I just deleted it because I wasn't going to need it.
I then laid out my interface for the first view (FirstView.h/m/xib) in IB. It had an image on the top, label under and a UITableView under that.
I sat up the correct connections (delegations and datasource for the tableview) in my FirstView.h/m file, and pressed Build. It seemed to build without errors, so I pressed Build and Go.
The Simulator popped up, installed the app and crashed. (Error message:Terminating app due to uncaught exception).
Complete error message:

I asked about this in another question, got an answer, and that fixed it:
It was obviously looking for code in the FirstViewController.h/m-file, although I did not do anything to make it look for code there.
I fixed this by adding two interfaces and implementations in my FirstView.h/m file. (FirstView and FirstViewController)
When I ran the app then, the table view and tab bar came up on the screen, but my image and label did NOT.
I don't have any idea of why it was looking for the code in FirstViewController instead of FirstView... I have the correct connections in IB, too..
A tableview is trying to query its data source for the number of rows it should display. If you've connected the tableview's datasource outlet to an instance of your FirstViewController class, then you need to implement -tableView:numberOfRowsInSection: in that class.
I have a problem with my application for the iPhone.
It's a tab based application. In one of the tabs, I have a Table View. I have set it up to load in data from a PLIST.
My problem is that when I try to build and run it, the application either crashes, or stays at a black screen with the error message "Terminating app due to uncaught exception".
I looked in the console, and found that the error probably laid in this string:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return workouts.count;
}
(error message:)

Building the app does not generate any errors.
Please help me? Thanks :)
If you look at the actual text of the exception, 'NSInvalidArgumentException', reason: '*** -[FirstViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x39101a0', you can see the root of the problem. Somewhere in your code you're calling tableView:numberOfRowsInSection: on a FirstViewController, which doesn't implement that method.
Exceptions are not caught at compile-time, but rather thrown at runtime. You may want to read up on them if you aren't familiar, as they're a fairly important part of many programming languages.

I'm guessing, since FirstViewController is one of the standard example classes created when starting a new Tab Bar based application in Xcode that you haven't changed its super class or implemented the methods of UITabeViewDelegate and UITableViewDataSource.
Either that or you've implemented the methods from those protocols in another class, but set FirstViewController as the table view's delegate/datasource.
We need more information to know for sure.
