如何通过 CodeSense 在 Xcode 中显示文档？

Question

I am Java developer and would like to know how I can get the equivalent of a JavaDoc in Xcode when CodeSense is doing its auto-complete? If I hit the ESC button I can get a list of methods etc. but it does not show me the descriptions of what the methods do.

Answer 1

I am new to xcode and mac. Bring your mouse over the method name and press alt + left mouse click to see help. To see full help press alt + double mouse left click .

Answer 2

It's not quite the same, but the close equivalent is Quick Help, accessible from the Help Menu. It's a floating palette that dynamically shows a quick documentation for the method or class at your cursor position.

Answer 3

Just to add to the topic, on Xcode 13 you can invoke quick help by using:

⌥ (option) + mouse click 

On any method, function, structure and etc...
