How to use ARC converter for a single file in a ARC project?

Question

The project is already an ARC project.

But some files are manually disabled arc by putting a -fno-objc-arc flag in its compiler flags.

Now I want use xcode's arc convert tool to convert some of the non-arc file into arc. How can I do this?

Since the project in now already arc. If I try to run the convert tool it just generate too many errors no matter how many files selected

Answer 1

If you really want the tool, you could just move the source(s) to a dedicated transitionary target (e.g. static library) and then just convert that target.

If all else fails, just remove -fno-objc-arc from that source, then review properties and remove the compiler warnings, etc.
