Why Choose Comment Reflow
- Built for Swift & DocC — Parameter lists, bullet points, code blocks, and callouts are re-wrapped correctly, with their structure and indentation preserved on every line.
- One Command — Run “Reflow Line Comments” from Xcode’s Editor menu or assign your own keyboard shortcut.
- Your Line Width — Wrap at 72 columns by default, or pick any width that matches your team’s style.
- 100% Private — Comment Reflow runs entirely on your Mac. Your source code is never sent anywhere. No ads, no tracking, no account.
Right Where You’d Expect It
A lightweight Xcode Source Editor Extension that feels like part of Xcode itself.
Editor Menu Command
Find Reflow Line Comments under Editor → Comment Reflow. Place your cursor in a comment, or select part of one, and run the command.
Your Own Keyboard Shortcut
Assign any shortcut in Xcode’s Settings under Shortcuts and reflow without leaving the keyboard.
One Comment, a Selection, or a Whole File
Select a larger range — even an entire file — to reflow every comment block inside it in one pass, while your actual code stays untouched.
Wrap at Your Line Width
Match your team’s style guide or line-length limit.
Any Column Width
Pick the column width your comments should wrap at. The default is 72 characters, a classic choice for readable documentation comments.
Applies Immediately
A new width takes effect the next time you reflow a comment in Xcode. No restart needed, and you can reset to the default at any time.
Key Features for Your Comments
- Line & DocC Comments — Reflows both
//line comments and///DocC documentation comments. - Structure-Aware Wrapping — Keeps parameters, returns, bullet lists, code blocks, and callouts correctly formatted when lines are re-wrapped.
- Indentation & Markers Preserved — Every wrapped line keeps its indentation and comment marker, so nested code stays tidy.
- Multiple Comment Blocks at Once — Reflow a selection or a whole file in a single command.
