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.
