Our main window has a tool bar across the top, an outline view on the left, and a tab view on the right. Choosing an item from the outline view fills a data entry screen into a new tab on the right.
We started out using OS 10.11, but just switched to newer OS versions. 10.12 has a couple display quirks but runs OK. In 10.13 and newer, switching tabs often crashes. It gives a warning about releasing a data entry field that is already released. In C++, we would diagnose this with a breakpoint in the destructor and then check the stack trace. But with ARC, a breakpoint at dealloc just shows performDelayedCleanup and then main. No clues to what's wrong. Is there lore or are there tools for tracking object lifetimes in Obj-C/ARC? Anything that changed in 10.13 that might be biting us?
