My favorite Xcode tip
My favorite Xcode tip is a few related tips on navigating within a file.
1. With a source file in front, use ctrl-2 to popup the list of functions.
2. Navigate the menu using the keyboard—including type-ahead find.
3. Within your source files, use
#pragma mark Whatever to set off sections. These appear in the popup menu in bold, making it easy to find sections.
(Like many, if not most, Mac developers, my goal with Xcode is to never have to touch the mouse.)
