I'm trying to mark a couple of files as non-ARC. But for some reason, under Compile Sources in the Build Phases of my target, it won't let me edit them. Does anyone know what's going on? When I double click the column under Compiler Flags, the row that contains the filename is in turns grey.
Does anyone know what's going on?
If the files are external from external libraries you have added to your project you may want to delete them from your project, re-add them and make sure you click the "add to targets" - "your app name" check box. Then try double clicking the row again in compile sources.
EDIT: (ANSWER) If you're on a retina macbook pro, this may be your issue. I solved it by going to the compiler flags, hitting enter/double clicking on the one I want to edit, and typing even though I can't see anything happening. Hitting enter will then finish editing the compiler flag for this row (or rows if you do a multi-select).
