How have you detected and eliminated memory leaks in your projects?

To detect and fix memory leaks in iOS projects, I use the following approaches:

• Instruments tool (Leaks, Allocations) — allows tracking objects that are not released and finding leak locations.
• Profiling with Xcode Memory Graph Debugger — visualizes the object graph in memory, helps identify cyclic references.
• Code analysis for retain cycles — especially important to check closures and delegates, using weak/unowned references.
• Using Automatic Reference Counting (ARC) — ensure there are no strong retain cycles.

Example of fixing a retain cycle in a closure:

class ViewController {
    var closure: (() -> Void)?

    func setup() {
        closure = { [weak self] in
            guard let self = self else { return }
            print(self)
        }
    }
}

This approach prevents holding onto self inside the closure, helping to avoid memory leaks.
