I'm trying to add an IBOutlet in swift but I only have the option to add an action.
Here is an image of what I'm talking about.

Is there any way I can fix this?
I can't change connection type either.
This is happening because you are trying to connect an outlet from the Interface Builder to a non-corresponding View Controller file, so that's why it only gives you the option to add an Exit action. Just make sure that you are in the same View Controller both in the IB and in the Assistant Editor.
P.S. I recommend you renaming properly every view controller so it will be easier to avoid this (make sure to change the name not only in the class but also in the IB). You can use the cmd + click when selecting the class name on the code and click on Rename... to change all at once. If you already changed it in your code, you have also to do it then manually in the IB, selecting the corresponding one from the drop-down menu of the Identity Inspector:
Try ctrl dragging it from the text on the left ()
Restart your Xcode and try to connect #IBOutlet
Simply change the connection type or one more thing you can do. you can do this. By opening connection inspector and drag the outlet into view controller like shown in image..
To Change Connection Type
You should use the same class in your view controller (call it View Controller.swift)
I am unable to make an #IBOutlet to my custom class from the elements in my prototype cell. I tried dragging from the element to the class; I let go of the blue line, and nothing happens.
Here are my files if you want to poke around.
Thanks in advance!
This is the issue:
Changing to this should fix this problem:
sometimes, some xcode tricks 'n hacks work, for example:
removing class name in storyboard for a cell;
restarting xcode;
cleaning project;
removing outlets and trying to prepare them again;
adding outlets using various techniques (ctrl+drag from storyboard, drag from an outlet defined in class file, drag from outlets tab - 'add new outlet')
removing cell class inheritance, then adding outlet, then adding inheritance back again
Make sure the CustomtableViewCell class is a Cocoa Touch Class file and not a swift file
I have created a custom view (Quantity View) with nib file in Swift. I have created some IBOutlets & IBActions (for buttons, labels etc.) in my custom view.
I tried to use this custom view (Quantity View) by assigning class name to a UIView in my storyboard.
It's showing me all the IBOutlets & IBActions in the Connections Inspector, as shown in this screenshot: .
I just want to show only delegate for the Custom view.
Possible Answer:
I thought I can use the -viewWithTag to get the views instead of Outlets.
But, I want to know if it's possible with having Outlets also or if there is much better way to do this?
What are the other possible ways (optimum) to handle this situation?
You can also consider the following solution:
You can take the subviews of your QuantityViews(custom view) and you can identify the specific views by its frame origin.
Note : you should know the customview subviews frame
Its not possible to hide IBOutlets from storyboard if you declare the class members as IBs (IBOutlets or IBActions).
The IBOutlets or the IBActions are just indicators to the interface builder so that it can show the names on it when you try to bind them it actually calls the setValue: forKey: method to set the view's reference to the IBOutlet property.
Now if you try to access an subview from the file's owner class without any IBoutlets you need to have a pointer to point it, so for that either you can get the reference using ObjectID which is assigned to the subview by the interface builder or you can get it using the viewWithTag: method.
The ObjectID you need to find all time when you add or replace a subview from the view, so better and convenient approach is to use tag property of UIView class.
So my conclusion to this problem is to access the views using the viewWithTag method you mentioned earlier.
I think your way is correct. But sometimes Xcode doesn't work correctly.
The following makes the IBOutlets and IBActions reappear and work properly:
Clean project your project in Xcode.
Quit Xcode completely.
Delete all contents of ~/Library/Developer/Xcode/DerivedData/.
Restart MacOS just in case.
I hope you will resolve that :)
I can't control-drag anything from my screen to ViewController.swift. This is making me very mad and I don't know how to fix it. I have been looking on the internet for hours and can't seem to make it work.
May be the class of your xib will not be the viewcontroller to which you are controll dragging.
Or,It can be because your zoom out level is high..Zoom in to say 50 or 100% and see if you can control drag.
If it wont connect you must set the File's Owner in the XIB file. Select File's Owner in the Placeholders panel. Move over to the Utilities panel and make sure the Custom class, in Identity Inspector, is set to what ever your viewcontroller is named.
I Hope this will help you.
Cheers!
After upgrading to Xcode 6, I opened an old project (that contains a subproject, so it has many targets)
and I noticed that no link from my Storyboard ViewContoller to the relative Objects works.
For example I have a ViewController with a TableView inside and now I cant do can't do anyhing with it because the connection is missing, I can't even redefine a new IBOutlet in the VC because the arrow in the storyboard from the VC won't connect to anything.
To be more clear:
The class is defined in the Custom Class section, so I can't find the problem
What should I do?
Btw I'm using obj-c not swift, I found some related answer but all about swift.
You can also see that the link between the parent view and the custom class is broken (not visible anymore) which is a huge problem.
I had the exact same issue with the app i'm working on actually, updating XCode from 5.xxx to 6.1. The workaround that worked for me was to remove the reference of every view controller and re-add them to the project...
To everyone facing that issue, here's the (annoying) trick :
Step 1 : select both .h and .m view controller files
Step 2 : remove the reference of those files
Step 3 : re-add the files to your project tree
Step 4 : open the storyboard, eventually re-build the project and smile
I can understand those things could be reaaally annoying, but it worked for me... Hope it will help someone else !
In your storyboard hierarchy select the View Controller,
In the right pane Custom Class section Class, select the drop down and your desired view controller.
I've experienced similar behaviour in Xcode 6.1.1 when trying to add the first outlet to a new view.
Tried removing the references and adding the files again as suggested above with no success.
What I did find worked was writing the first property on the new view by hand. I just popped in:
#property NSString *temp;
I could then attach my outlets in the normal way. Just delete the temporary property once you've added your first outlet.
Hope this helps.
It seems typing the outlet first (swift):
#IBOutlet weak var someViewOutlet: UIView!
and then dragging from IB the outlet to the far right type in the above code works.
Restarting Xcode resolves the issue (sometimes). Using Xcode 6.1
Maybe I can help
In my case the problem was that the viewController.swift file was not connected to the StoryBoard. The solution is to click in the Upper border of the view on the storyboard beside the 3 icons (View Controller, First Responder and Exit)...now look over in the Utility Area choose Identity Inspector, and in "Custom Class" choose the custom view controller.
Hope this helps. Xcode is hard!!
Here's the proper solution i believe.
If you renamed the controller in code, you need to update the .xib file.
I could not find a way to do it in the interface builder, so do this:
Open the .xib file with a text editor: right click the file > open as > source code
In the <objects> node find the <placeholder> node with the property placeholderIdentifier="IBFilesOwner" and replace the value in customClass="MyOldControllerName" with your new controller name: customClass="MyNewControllerName"
And all your IBOutlets will work as normal again.
Thanks to everyone who commented.
It is a bug of Xcode 6 / 6.0.1. Downloaded and installed the 6.1 version and the problem disappeared.
Maybe try to delete the outlet from the menu in the storyboard (in your screenshot) and drag it again of the element.
Okay, let's check iff it is the lack of a module name.
In your storyboard ViewController, type in the name of module. (the project name)
2.Clcick outside in another field. When you go back to the module field it may say none, but now there will be a dropdown menu entry for your project name.
Select your project name and see if everything is good.
If there are still issues I will post photos.
Seems to be a workspace issue. Try to remove project form a workspace and add it again. It helped in my case.
I had this, affected all projects on my machine, swift and objective c and drove me mad for ages. Finally also noticed that I could not use the refractor to rename classes either.
The fix for me was:
Close xcode
Delete ~/Library/Developer/Xcode/DerivedData (just doing this on its own did not work!!)
Delete all user data for all my projects using the following from the directory that contains all my projects e.g. /src (be careful with this command!):
find . -name 'xcuserdata' -exec rm -rf {} \;
If you want to do it by hand just do the following for all your projects
Delete .xcodeproj/project.xcworkspace/xcuserdata
Delete .xcodeproj/xcuserdata/.xcuserdatad
Get Spotlight to re-index the drive all my projects were on (not sure if this was required
Re-boot machine
Everything sprang back into life !
I was having this same issue.
It turns out I renamed my view controller class and file name. In storyboard, I had the stale value in the right pane, Custom Class -> Class. So the IBOutlets were not aligning because there were none in the missing class, which is where it was expecting to find the defined outlets.
Filling in the correct class name of the View Controller in the Custom Class field in the right pane fixed my issue.
XCode needs to be more verbose if you have a bad class name in the Custom Class fields.
no one solution fixed my same problem...
But i have solved by:
close xcode
renaming the folder of the project
open xcode
and then the outlets will be back again
I hope that this solution is the right one for the people who have the same problem
In Xcode 6.3 I needed to close Xcode and restart the Mac. Restarting Xcode alone didn't do it for me.
I've had 6.3 for a long time and my problem was with new projects I was creating to test some things. Definitely not an upgrade issue this time.
I have Xcode 6.3 and saw similar issue. Finally few edits in .h file resolved my issue. If your interface has IBOutlet defined as
#interface NavigationViewController :UIViewController
{
IBOutlet UILabel *lblName;
}
change this to and in .m file add #synthesize lblName;
#interface NavigationViewController :UIViewController
{
__weak UILabel *lblName;
}
#property (nonatomic, weak) IBOutlet UILabel *lblName;
I was having this same problem, with no view outlet available to link to. The only way I was able to fix it was to change the owner class of the XIB file to "UIViewController," make the link, and then change it back to my intended custom view controller class. The link stayed and all was well.
