Xcode 9, Refactor > Rename

New in Xcode 9 you can rename an outlet (or action) in the code and storyboard at the same time.

*DISCLAIMER: This feature only works in Xcode 9 (released September 2017) and above. Make sure to backup your project before using it. After making outlet name changes, test the affected screen(s) to make sure there are not issues. I tested this in a sample Objective C project successfully but it could cause problems in existing, more complex projects.

To rename an outlet...  

1. Navigate to outlet in the header file

@property (weak, nonatomic) IBOutlet UIButton *btnRequestCode;

 

2. Right click on outlet, select "Refactor > Rename...".

 

3. Change the outlet name

4. Select the "Rename" button or the Enter key

 

The outlet is renamed in the code and storyboard

@property (weak, nonatomic) IBOutlet UIButton *requestCodeButton;
