Memory Graph Debugger
summary
Xcode 8 introduces a visual Xcode 8 Memory Graph Debugger that pauses the app and shows who retains what; a demo creates a parent/child view controller retain cycle where the child holds a 10,000-element array and a closure captures objects, producing a circular reference. The graph highlights the cycle (reported as 20 leaks though only one or two are real), lets the presenter confirm fixing with weak references, and loads in about 5–10 seconds on an older Mac.
