How to download my current build to edit

I need to make some edits to my app. I don't have the app on my computer so I want to download it from my developer account. I can't seem to find any information on how to do that. Could someone please explain where to go to download my code and edit it.

Thank You, Colby

Apple doesn't have your source code to download.

You should have the code on your Mac if you developed the app. If someone developed the app for you, they have the source code. Get the code from them.
