Sadly, nothing changes after the syntax changes. @property (strong) also
fails.

We tried that last week. The problem with ARC debugging is that
breakpoints in dealloc()
happen long after the release. You know it died, but not when or how.
Sometimes we turn off ARC for one class with compiler directives, then
breakpoint on release.
But Apple code does many retains and releases, all in Assembly code. It
probably wouldn't
be too hard to figure out if source were available, but it's not. We used
to step through PowerPlant
code a lot, and found/fixed several bugs for them.
