All answers above are almost correct BUT if you have push notifications enabled and all options disabled (alertSetting, lockScreenSetting etc.), authorizationStatus will be authorized and you won't receive any push notifications.

The most appropriate way to find out if you user can receive remote notifications is to check all these setting values. You can achieve it using extensions.

Note: This solution works for iOS 10+. If you support older versions, please read previous answers.

extension UNNotificationSettings {

    func isAuthorized() -> Bool {
        guard authorizationStatus == .authorized else {
            return false
        }

        return alertSetting == .enabled ||
            soundSetting == .enabled ||
            badgeSetting == .enabled ||
            notificationCenterSetting == .enabled ||
            lockScreenSetting == .enabled
    }
}

extension UNUserNotificationCenter {

    func checkPushNotificationStatus(onAuthorized: @escaping () -> Void, onDenied: @escaping () -> Void) {
        getNotificationSettings { settings in
            DispatchQueue.main.async {
                guard settings.isAuthorized() {
                    onDenied()
                    return
                }

                onAuthorized()
            }
        }
    }
}
