Re-binding self: the debugger's break(ing) point

This technical article details a now-fixed bug in Xcode where using backticks to re-bind 'self' inside a weak closure (e.g., `guard let `self` = self`) would break the LLDB debugger within that scope. It explains the historical weak/strong self patterns in Objective-C and Swift, demonstrates the debugger error, and discusses why the workaround was problematic for debugging.
