This workflow is a replication of my "tm:select" command of the Text Massager Workflow done in Swift. You have to have xCode 6 beta 6 to recompile the executable, but it should run on any system that is OS Maverick and up. Instructions for recompiling the Alfred Swift Library and the program is in the workflow directory. The one command is "tc:convert". The string given will be shown in capital case, upper case, lower case, and title case.
I would appreciate feedback if someone would run this on a system that has never had xCode 6 installed. I suspect a dynamic link library issue, but I am not sure. There is not much documentation on static linking of Swift code, so I am blazing a new trail.
