    Editor

    Indentation

    • Go to Xcode Preferences.
    • Choose Text Editing tab.
    • Switch to the Editing page underneath.
    • Check both Automatically trim trailing whitespace and Including whitespace-only lines.

    This will not add extra whitespaces when choosing Re-Indent in the Editor for the specific selection of code or file.

    Key binding

    How to delete a keybinding on Xcode ? (using version 9.3 of Xcode)

    The first method is obviously the little - that sometimes appears when double-clicking a binding.

    The second method is not so quick but (in my experience) just as efficient. (Here I am assuming you've got a personalised keybinding profile already. If you don't, create one. I'll call it Personal.)

    1. In Xcode: select the shortcut you want to remove and attribute it a random binding (even one that causes conflicts, you'll delete it in two minutes, you don't really care).
    2. Quit Xcode.
    3. Go to ~/Library/Developer/Xcode/UserData/KeyBindings/.
    4. Open the file personal.idekeybindings (it's a simple XML file, any decent text editor should be able to handle it).
    5. Find the shortcut you modified and want to delete by searching its name using command + F.

    You should then find something looking like this (each dict corresponds to a modified shortcut):

    <dict>
    <key>Action</key>
    <string>execute:</string>
    <key>Alternate</key>
    <string>NO</string>
    <key>CommandID</key>
    <string>Xcode.IDEPlaygroundEditor.CmdDefinition.Execute</string>
    <key>Group</key>
    <string>Editor Menu for Playground</string>
    <key>GroupID</key>
    <string>Xcode.IDEPegasusPlaygroundEditor.MenuDefinition.Editor</string>
    <key>GroupedAlternate</key>
    <string>NO</string>
    <key>Keyboard Shortcut</key>
    <string>^&lt;</string>
    <key>Navigation</key>
    <string>NO</string>
    <key>Title</key>
    <string>Execute Playground</string>
</dict>

    Delete this part:

        <key>Keyboard Shortcut</key>
    <string>^&lt;</string>

    Do that for each shortcut you want to remove and don't forget to save the file before closing it. Now open Xcode and check for the shortcut: the space for the keybinding should be empty.
