Trim trailing spaces in Xcode

Question

Is there a way to force Xcode to trim trailing whitespaces when I save file?

I\'m using version 3.1.3 if that matters.

Answer 1

For Xcode 8, I installed the swimat Xcode plug-in, for formatting Swift code, which removed all trailing spaces and whitespace-only lines.

Installation Methods

1. Install via homebrew-cask:

   brew cask install swimat
   

2. Download the App directly:
   https://github.com/Jintin/Swimat/releases/download/v1.3.5/Swimat.zip

3. Clone extension branch and archive to Mac App.

Usage

Once installed, you can run Swimat in Xcode via Editor -> Swimat -> Format.
