However I do not think I am doing something wrong with my code this is my viewdiappear. What did I miss out so that this kind of error is created?
- (void)viewDidAppear:(BOOL)animated {
PFUser *user = [PFUser currentUser];
if (user.username != nil) {
[self performSegueWithIdentifier:#"login" sender:self];
}
}
It seems like you haven't set the name of the segue in the storyboard. The picture below is the name of one of my segues, for you, the text box would contain simply login.
It can also happen when you forget to "Embed" the storyboard in Navigation controller:
What the error is telling you is that although your storyboard may contain a segue called #"login", it does not emanate from this LoginViewController (the one that is currently self).
You may think it does, but trust me, the runtime knows more than you do.

I really do not know what mistake am I doing in the following lines:
// Instantiate SecondViewController
let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "RegistrationScreen2View") as! RegistrationScreen2ViewController
self.navigationController?.pushViewController(secondViewController, animated: true)
I am not able to move to second view controller in the story board I have mentioned story board id as RegistrationScreen2View for RegistrationScreen2ViewController.
I am getting the following exception:

Please let me know what mistake am I doing.
Your code should work. The most possibility is that you forgot to input an Storyboard ID for your destination ViewController.
***How to Fix:
In the Identity Inspector of destination ViewController, enter its ID.
I just started recently. I can't fix it and I don't know How to do
I have attached files and images. When I run my app, I receive the following error:

Your error tells you exactly what you need to do.
Receiver (<login.ViewController: 0x7fc0d94b28d0>) has no segue with identifier 'loginView'
so check your segue in storyboard and ensure that segue identifier from LoginViewController is loginView.
The log error is as follows

"[UITableViewController loadView] loaded the "jgh-55-9I5-view-Ywb-7c-HKv" nib but didn't get a UITableView."
This is saying that somewhere in your storyboard there's a UITableViewController or a subclass of it which has its view property connected to something that is not a UITableView or subclass of that.
Check each view controller in the storyboard to make sure its view is connected to something appropriate.
I want to use sender to get the value from segmented control, but I am getting the unrecognized selector sent to instance error. The segmented control was added within a view. I've tried removing the semicolon and/or sender and none of the prior posts I've found seem to help. Any ideas?
Swift Code
var segCntrl = UISegmentedControl(items: ["Yes","No"])
segCntrl.tag = 100
segCntrl.center = CGPointMake(qView.bounds.width/2, qView.bounds.minY+40)
self.qView.addSubview(segCntrl)
func segmentorSwitch(sender: AnyObject) {
if(sender.selectedSegmentIndex == 1) {
println("Yes selected")
}
else if(sender.selectedSegmentIndex == 2) {
println("No selected")
}
}
segCntrl.addTarget(self, action: "segmentorSwitch:", forControlEvents: UIControlEvents.ValueChanged)

Looks like segmentorSwitch: is implemented inside another method. Define it outside the method in which your code is contained, and this should be fixed.
I am a total newbie with objective C and IOS programming trying to follow along with a tutorial on the Apple Website.
I got to the point in the Apple tutorial where you add an unwind segue to the Add to-do page.
https://developer.apple.com/library/ios/referencelibrary/GettingStarted/RoadMapiOS/SecondTutorial.html#//apple_ref/doc/uid/TP40011343-CH8-SW1
I successfully added unwind segues to both the Cancel and Done buttons.
However, when I compiled the program, while it compiles, it no longer lets me click on + to get to the add to-do page.
When the simulator initially loads, it is fine. But when I click on +, Xcode appears in front of the simulator and in the debugger it says what is below.
Note I have no experience in debugging. What appears in editor is main.m and the following is in right side of debug section at bottom:
