Code folding in Xcode 8

Question

Is anyone having problem with code folding in Xcode 8? Every time I fold GameScene.swift (or any other file), switch to, for example, AppDelegate.swift, and switch back to GameScene.swift (which were folded before), it unfolds.

Answer 1

Xcode unfortunately neither store nor remembers code folding. It actually resets folded parts after losing focus that file.

Since the code folding is reset all the time, I personally use this way of refolding:

To fold all the methods: Shift + Alt + Cmd + <- left

Place cursor onto the desired method and unfold it by clicking or using shortcut: Alt + Cmd + -> right

Answer 2

With Xcode-9, this issue is resolved. Code folding is being remembered and saved by Xcode 9 Editor.

Code you have/had folded exact before last source build/save, is automatically stored upon document/file closure. And same will be visible as it was (folded) when you will open document/file next time.

You don't need to do anything (there is no any option in Xcode tool bar to enable or disable) to save your code fold.
