I think Swift syntax is actively getting in the way in LLDB. When debugging you want to be able to look at data in a more free-form way and get a bit closer to the metal. The C expression syntax works pretty well for that, but in Swift mode I was stymied. >> It does, when I enable MallocScribble. Could you explain the syntax to set a >> watchpoint, too?

It kept giving errors like "expression evaluation of address to watch failed”. That’s why I posted in the first place. This might be another instance of Swift syntax not working well. I was stepping through assembly code and had the address of an object in a register, and wanted to detect when that object was modified. LLDB may have been rejecting my commands because the Swift mode wasn’t recognizing a numeric value as an address. —Jens
