How can I display documentation in Xcode via CodeSense?

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

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.

…and which is also accessible by Option-double-clicking a keyword in your code. – Blowup

is there no way to automatically read documentation on the fly as the auto-sense pops up? – Les

I don't believe there is. To be honest, I find the method names themselves so descriptive that I don't find it necessary. Even the longer abstract in quick help is often completely redundant with the method name. E.g. NSString's drawInRect:withAttributes: has this in Quick Help: Abstract: Draws the receiver with the font and other display characteristics of the given attributes, within the specified rectangle in the currently focused NSView. – Batista

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.

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...
