Xcode, how to expand all collapsed loops in the source code view?

Question

if you collapse the view of a loop (so that it shows the ellipses ... instead of the lines inside the loop) and you do this for many loops, is there a way to quickly expand all of them back to showing all lines of code again?

Answer 1

Go to menu-->editor-->Code Folding-->Unfold all

Answer 2
