iOS에서 메모리 누수를 쉽게 감지하는 방법

환경

Xcode 10.1
Build version 10B61
Apple Swift version 4.2.1 (swiftlang-1000.11.42 clang-1000.11.45.1)
Target: x86_64-apple-darwin18.2.0

도입 방법

1. pods or carthage에서 LifetimeTracker 설치

pods

pod 'LifetimeTracker'

carthage

github "krzysztofzablocki/LifetimeTracker"

2. 설정 처리를 AppDelegate에 추가

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
     LifetimeTracker.setup(onUpdate: LifetimeTrackerDashboardIntegration(visibility: .alwaysVisible, style: .bar).refreshUI)
     return true
}

3. 메모리 누수를 조사하고 싶은 ViewController에 구현을 추가

import UIKit
import LifetimeTracker

class ViewController: UIViewController {
    static var lifetimeConfiguration = LifetimeConfiguration(maxCount: 1, groupName: "VC")
    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
        trackLifetime()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        trackLifetime()
    }
}

extension ViewController: LifetimeTrackable {}
