Xcode 9 Jump to definition in a new tab, window, or other navigation area with Option-Shift-Command+Click

Question

Xcode 9 seems to be missing jump to definition shortcut Option-Shift-Command+Click. You used to be able to use to open definition in a new tab, window, or other navigation areas with Option-Shift-Command+Click. In Xcode 9 this still works from the file navigator but not when you use this on a class. Has anyone been able to figure out how to use this shortcut in xcode 9?

Answer 1

First, Open the file.

Then:

• New Window : Cmd + Shift + t
• The Assistance Editor : Cmd + t

Answer 2

Marco's screenshot was helpful.

The keyboard commands for Xcode 9 have changed:

Jump to Definition

• Same window : Command-Control-click (was Command-double-click)
• In assistant pane : Command-Option-Control-click
• In separate window/pane : Command-Option-Control-Shift-click

Quick Help

• Option-click (same as Xcode 8)

Answer 3

You can use Xcode preferences to personalise the double click and the action selector.

From this window you can change CMD + click to open the definition instead of the action selector (as it was in Xcode 8)

you can also change the behaviour of optional navigation, so that it opens a tab

By setting the configuration as shown below, you can CMD + ALT + click to jump to definition in a new tab.

This also restores Option-Shift-Command+Click to show the window selector as you wanted

Answer 4

As soon as I asked a question I found a solution by accident.

1. Command + click on the class to bring up the new action selector
2. Shift + Alt + Click to chose where to open (tab, new window, etc)

Alternatively, can use Command + Option + Control + Shift to do this all at once but I'm not sure how convenient that is
