In Xcode, you can enable multi-line cursor editing, which allows you to type or edit text at multiple locations simultaneously. This can be incredibly useful for making the same edit on several lines at once. Here’s how you can do it:
- Using the Keyboard Shortcut:
- Hold down the
Optionkey and drag your cursor vertically. This will create cursors at multiple lines. - You can then start typing, and the text will be inserted at all cursor positions.
- Hold down the

Shift + Controland then clicking at each point where you want a cursor. - This method is useful if the lines you want to edit are not directly above or below each other.

- Selecting Similar Text:
- Select a piece of text.
- Then use
Editor -> Find -> Select Next Occurrence(or the corresponding keyboard shortcut, which is usuallyControl + Command + E). - This will add another cursor at the next occurrence of the selected text, allowing you to edit all instances simultaneously.
- Removing a Cursor:
- If you have multiple cursors and want to remove one, just click at the location of the cursor you wish to remove.
Multi-line cursor editing is a powerful feature in Xcode that can save a lot of time and effort when you need to make the same change on multiple lines of code. However, be mindful when using it, as it’s easy to inadvertently make changes you didn’t intend.
