What methods do you use to detect memory leaks in your projects?

Answer from AI

To detect memory leaks in iOS projects, I usually use the following methods:

  • Using the Instruments tool (especially Leaks and Allocations) to monitor memory usage and identify leaks.
  • Analyzing retain cycles with the Xcode Memory Graph Debugger.
  • Checking the correct use of weak and unowned references in closures and delegates.

Example: if object A retains object B, and B in a closure retains A without weak, a retain cycle occurs, and memory is not released.

class ViewController {
    var closure: (() -> Void)?
    func setup() {
        closure = { [weak self] in
            print(self?.description ?? "No self")
        }
    }
}

Using [weak self] here prevents a leak.
