Use Memory Graph Debugger in Xcode to locate retain cycles and inspect object reference chains. It captures memory snapshots to visualize strong references preventing deallocation, helping you identify which closures or delegates hold objects alive.

Your view controller fails to deallocate after navigation due to strong reference cycles in closures, active timers, or notification observers that were not removed. Profiling with Instruments can quantify these leaks and track the specific allocations keeping the object alive.

The best way to debug timer and observer leaks is using Instruments memory profiling to track allocations and Memory Graph Debugger to trace reference chains. Ensure proper deinitialization and deregistration of observers to prevent these common lifecycle leaks.

Yes, you can use Instruments to profile memory leaks in a macOS app. Instruments memory profiling workflows quantify leaks and track allocations across timers, observers, and closures, while Memory Graph Debugger helps inspect the specific retain cycle chains.

To stop Combine cancellables from leaking in production Swift code, store subscriptions in a collection tied to the object's lifecycle. This ensures proper deinitialization and prevents retain cycles that keep view models and observers alive unnecessarily.

Yes, Memory Graph Debugger works for finding closure leaks in iOS by capturing memory snapshots and inspecting strong reference chains. It helps identify where closures capture self strongly, allowing you to apply weak self patterns to resolve the deallocation issue.
