Has anyone made a custom macro within Xcode? Some editors of the past have offered a language and support to customize the editor. You could define a key to invoke a custom routine to do something like insert a dated comment. Example: If you wanted to make a note to self, you could press a key like F8 and have it insert documentation that you wanted instead of typing it out. Something like: /* #Date# */ I see this from SO: http://stackoverflow.com/questions/5013332/how-to-create-custom-text-macros-in-xcode It has an example like this: What I'd like to see is some documentation on this, maybe a chapter in a book or something that would show all the details. The link from the SO answer goes here: http://blog.ablepear.com/2010/01/code-completion-in-xcode-how-to-make.html However, it's about 6 years old Even the SO link is about 5 years old. Maybe someone has done some of these of knows of a tutorial site or something.
