Unused "IBOutlet" cannot remove from "File's Owner" "Connection Inspector", "OutLets" List

Question

I copied FairListViewController class to my project. I renamed it to ExibitorViewController.

There is an IBOutlet called

UITableView *fairListTableView;

in nib file. I change it with

UITableView *exibitorTableView;

Now every thing works fine. But one thing I notice that the previous tableView IBOutlet (which is fairListTableView here)" name still listed on the

ExibitorViewController.xib > File's Owner > Connection Inspector > OutLets section.

Though it was unconnected and don't bother at all. To erase it, I have to go to the nib xml file. I've done the following steps:

1. right click on ExibitorViewController.xib
2. File > Open As > Source Code
3. search for the (Control+F) fairListTableView
4. delete the related code from there.

The code I found is :

<string>fairListTableView</string>
   <object class="IBToOneOutletInfo">
      <string key="name">fairListTableView</string>
      <string key="candidateClassName">UITableView</string>
   </object>

But after saving and cleaning the project that IBOutlet still shows up there. If anyone knows the tricks to remove it, please share with me.

Answer 1

Sometimes I have the same problem. Make sure you remove it from the Interface Builder, Product -> Clean and then restart Xcode.

That usually does the trick for me

Answer 2

Have you tried removing it in Interface Builder, instead of changing the .xib XML? XCode most likely saves what's present in Interface Builder when quitting, so it may overwrite any changes you did manually.

Answer 3

I found that I needed to delete the DerivedData folder for my project to get the "cached" IB references to be removed. Clean and restart was not working.

Using Swift and xCode 7.2. YMMV
