闭包 #2 thunk for @escaping @callee_guaranteed () -> ()

Question

我在我的函数中的 Crashlytics 报告闭包 #2 中得到了这个，下一行是 @escaping @callee_guaranteed () -> () ()

这是我的职能：

func myFunction() {
        var isLogin = false
        let group = DispatchGroup()
        group.enter()
        let greetUser = { (name: String)  in
            if name != nil {
                isLogin = true
                group.leave()
            } else {
                isLogin = false
                group.leave()
            }
        }
        greetUser("reportMe")
        group.notify(queue: .main, work: DispatchWorkItem(block: { [weak self] in
            Crashlytics.crashlytics().setCustomValue(Date(), forKey: "Date")
            Crashlytics.crashlytics().setCustomValue("https://example.com/", forKey: "URL")
            Crashlytics.crashlytics().setCustomValue("wah ada error nih", forKey: "error")
            Crashlytics.crashlytics().setCustomValue(true, forKey: "is_login")
            Crashlytics.crashlytics().setCustomValue("10.10.10.101", forKey: "ip_address")
            Crashlytics.crashlytics().setUserID("123456")
            let error = NSError(domain: "https://example.com/", code: 101, userInfo: nil)
            Crashlytics.crashlytics().log("Report Me")
            Crashlytics.crashlytics().record(error: error)
            self?.showToast(message: "Crash Reported for Firebase Crashlytics to test whatever it received or not in Crashlytics", font: .systemFont(ofSize: 12.0))
        }))
}

如何修复我的函数中的代码，使 @escaping @callee_guaranteed () -> () 的闭包 #2 thunk 不再出现在我的 crashlytics 报告中？
