Cannot create new outlets in interface builder, old ones have a warning symbol

Question

I am not sure what is causing this problem, but I now cannot create outlets. When I create an outlet it appears and works fine in code, but does not appear under the view controller in storyboard. Old outlets have a warning symbol on them like this

When I remove this outlet, its gone and does not appear back to connect. I am running Xcode beta 6.2 because moving to 6.2 temporarily fixed this problem because I was having it beforehand in 6.1.

Here is the .h file of this class

#import <UIKit/UIKit.h>

@interface DashboardViewController : UITableViewController {
   NSString *currentDay;
}
@property (nonatomic, weak) IBOutlet UILabel *dayLabel;
@property (nonatomic, weak) IBOutlet UILabel *blockLabel;
@property (nonatomic, weak) IBOutlet UILabel *currentClassLabel;

@end

and here are the outlets listed in storyboard enter image description here

enter image description here These are the details of the warning, but this is .h file's code for this class

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface InfoViewController : UIViewController {
  IBOutlet UIScrollView *AISScrollView;
  IBOutlet MKMapView *AISMapView;
}
 -(IBAction)studentHandbook:(id)sender;
 @end

r u deleted the button action in anywhere in your view controller — Anbu.Karthik, Dec 01 '14 at 10:12
check in interface builder the view is connected or not? if view is not connected means shows like that only. — Aruna kumari, Dec 01 '14 at 10:23
1) restart xcode, 2nd) check if class file is same for viewcontroller on storyboard. — Sheshnath, Dec 01 '14 at 10:28
@sheshnath Restarted xcode multiple times, cleaned project, deleted derived data. View Controller in storyboard is the same as it is in code. The one weird thing is that when I type in class names, it does not autocomplete. I think this MAY have something to do with the Module as no module is set for the view controller. When I try to set a module no modules are available to select. — Eytan Schulman, Dec 01 '14 at 10:33
"I type in class names, it does not autocomplete" this is the issue, do you have xcode5, if yes try to bind class names with this. — Sheshnath, Dec 01 '14 at 10:37
have you properly set class file in viewcontroller on storyboard(show identiy Inspector -> CustomClass -> class) check class name for viewcontroller in storyboard — Aruna kumari, Dec 01 '14 at 10:39
@Arunakumari Yep, the class connected to the View Controller in storyboard is the same class that the outlets are in. — Eytan Schulman, Dec 01 '14 at 10:40

Oddly enough, I ended up finding a solution and that was moving the project out of the directory that it was in. It was in my Dropbox folder and moving it out fixed. If anyone has this problem in the future and also happens to have the proj in their Dropbox, move it out.

I don't know why I didn't think of this before, seems so obvious now. Thanks man! Moral of the story don't use Dropbox :) – Joe Barbour Jan 13 '15 at 19:07
@JoeBarbour I love and use Dropbox every day. Just don't use it for an Xcode Project. – Eytan Schulman Jan 14 '15 at 09:31

try to change this:

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface InfoViewController : UIViewController {
  IBOutlet UIScrollView *AISScrollView;
  IBOutlet MKMapView *AISMapView;
}
 -(IBAction)studentHandbook:(id)sender;
 @end

to that:

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface InfoViewController : UIViewController {

}
@property (nonatomic,weak) IBOutlet UIScrollView *AISScrollView;
@property (nonatomic,weak) IBOutlet MKMapView *AISMapView;

 -(IBAction)studentHandbook:(id)sender;

 @end

Changing the code to this does not do anything. When I remove the outlet that has the warning, the outlet just disappears and is not available to reconnect. – Eytan Schulman Dec 01 '14 at 14:05
I would suggest you to split the view - one side put the .h and in 1 side the xib. Ctrl+drag the UIViews (MKMapView and UIScrollView) from the storyboard to the .h and choose touchUpInside: or whatever you need. What is the output? – Gal Marom Dec 01 '14 at 14:23
When I try to control+drag the outlet from the .h file into the views with the Xcode split view enabled, it just won't highlight the views when I hover over them. Nothing happens when I release. – Eytan Schulman Dec 01 '14 at 16:04
try to do it the other way around - storyboard to .h - it should linked it automatically. but before discard the outlets at the .h and erase the connector at the storyboard. do clean just for case. – Gal Marom Dec 01 '14 at 16:37
So this created the outlet again, but the outlet appears with the warning symbol when created. The outlet says that no outlet with that name exists which is obviously not true because that outlet was setup by CTRL+Dragging. – Eytan Schulman Dec 01 '14 at 19:08
Weird... it's obviously a bug. Try to restart the computer, clean the project... – Gal Marom Dec 02 '14 at 10:01
Restarting the computer is unlikely to have an effect here. I'd suggest cleaning the build folder (Cmd-Opt-Shift-K) to clear the index. If this doesn't work, please file a Radar at bugreport.apple.com and include a sample project that reproduces so we can investigate. Do the connections work at runtime? Any console warnings? – Quinn Taylor Dec 03 '14 at 03:53

Just in case someone suffers from the same thing again, the best answer inside this other thread did the trick for me:

XCode 6: can't connect any IBOutlet to ViewController

Removing the .h and .m files from the project (their references) and readding them again was the solution that worked for me.
