I am trying to set the default indentation and tabs in Xcode 8.x to 2 spaces In the utilities I changes the default values from <code>4</code> to <code>2</code> <img src="https://i.stack.imgur.com/tPqpi.png" alt="Xcode Text Settings screenshot"> However nothing has changed. Did I miss something?

If you want to do this for all projects, you can set this globally in the Text Editing / Indentation preferences: <img src="https://i.stack.imgur.com/Z9vgj.png" alt="Text Editing / Indentation">

You have to go to every file and then to Ctrl + A then Ctrl + I which will indent the file with the two spaces. That setting does not touch files already created in the project.
