There’s a weird regression in Xcode 7. When execution is paused inside an Obj-C method whose class inherits from a specific abstract class in my library (CBLModel), any attempt to evaluate an expression involving that object fails with this error:
(lldb) po self error: class 'CBLModel' has incompatible superclasses note: inherits from superclass 'MYDynamicObject' here error: 1 errors parsing expression It only happens if the current stack frame is of a method on a CBLModel subclass, though. If I'm paused somewhere else and have a reference to a model, I can do “po model” (or something else involving it) and get a description. I’m not the only one seeing this; another developer using the framework I work on reported the same issue. This seems to be either an LLDB bug or perhaps something slightly wrong with my library that didn’t cause any problems until now; I’m not sure which. —Jens
