How can I find a line number in Xcode?

I have a function in my *.m file

- (void)myFunction {}

How can I find the line number this function?

You can go to:

Xcode > Preferences > Text Editing

then tick "Line numbers". Go to your method and you'll see the appropriate line number shown in the left-hand border of the text editor.

Go to Xcode Preferences > Text Editing > Show: Line numbers to show the line numbers on the editor.
