Is there a way to cycle through open windows. I quite often use this when I want to reference something in another file. On windows this would typically be Ctrl + Tab, but I can't find a way to do this in Xcode on a Mac.
On a Mac you can cycle through any program's windows using Cmd + ` (backtick)
On Xcode4 same command is achieved with Cmd + Ctrl + ↑/↓.
Basic MacOS stuff: ⌘` shift⌘`
See "system preferences>keyboard>keyboard shortcuts>Keyboard & text input" for all the juicy details.
All Cocoa: ⌘< and ⌘> to cycle through application windows.
Open Preferences/Key Bindings and look at conflicts. You may find CMD+< to be in conflict. As mentioned by @Nikolai Ruhe CMD+< / > should cycle through ALL app windows.
Once again: All applications are equal. But some applications are more equal than others. - Steve Jobs
Cmd + Tab switches from one application to another. Cmd + ` switches from one window to another within an application.
In the latest Xcode 7.0.1 onwards, you can now use CMD + ~. I spent a while to find out how to toggle between Xcode View Controller and the apple Documentation help I get upon CMD clicking. This works !
For people with German and possibly other non-US keyboards, the default key combination often do not work; for example, ⌘< doesn't work in many of Apple's own apps like Xcode or Numbers, Pages etc.
Even Apple's own suggestion of "Umschalttaste-Befehlstaste-Tilde (~)" here https://support.apple.com/de-de/HT201236 (in German!) doesn't work! This is probably because the tilde ~ is available only via a key combination itself on German keyboards.
My solution was to rebind the "Move focus to next window" shortcut to ⌘^. This works in all apps for me so far.
Although not exactly what you're looking for, F10 (or Fn + F10 depending on your keyboard setup), will show you all windows belonging to the open program.
On Xcode 6.4 CMD+SHIFT+< works to cycle through open windows :)
