How can I enable vertical split views in the Xcode IDE?

I'm diving into iOS developme开发者_C百科nt and I'm using Xcode on a multi-monitor setup.

Obviously I want to take advantage of the multiple monitors to view and edit multiple panes of source code, but I'm having a hard time figuring out how to enable vertical split views. In other IDEs, it's just an option you click in the "Window" menu.

How do I enable vertical split views in Xcode?

Xcode 4

Check out the options in the Navigate file menu item. I like Command+J. Also, while the Editor is active, i.e., you're editing code or your cursor is blinking in the Editor, press Command+Option+,. Or, you can Option-click (or Option+Shift-click) a file in the Navigator. Then, to make more room for editing, I like to press Command+0 to hide the Navigator and, if they're not already hidden, Command+Option+0 to hide the Utilities. Press Command+Enter to go back to the Standard Editor view.

Xcode 3

Hold down alt and click the little tiny box (with a horizontal line through it) in the upper-right-hand corner of the screen. It's underneath the tiny little lock icon.

Xcode 9 for those coming from a search engine:

Click and hold on the Assistant Editor button for an options menu. Choosing "Assistant Editors on Right" will cause the view to be split vertically.

This has changed in Xcode 12, maybe earlier. All my Option-Clicks go to open second view appearing below rather than size by side. The solution is to go to Views -> Change Editor Orientation

Use the dropdown on the split icon to choose between different views
