Code folding and unfolding in XCode 7.2

In the previous version of XCode, there was a little down arrow beside the source code editor for folding or unfolding the code. But in the new version of the XCode (7.2) that little arrow does not exist. It is very annoying to scroll up and down to find out the method which we are searching. On the other hand  the code editor looks really messy with unfolded code.
