如何从存储在CloudKit中的位置反转地理代码的经纬度？(How to reverse geocode latitude and longitude from location stored in CloudKit? - Swift 3)

 我想弄清楚如何将存储在CloudKit的CLLocation为地理编码。 我将该位置存储在记录中，我知道它存储为经度和纬度。 这是我的记录。 经纬度显示我现在只是拿出来了。 不过，我希望能够使用户可读的位置，所以AKA反向地理编码，以获得城市和州 。 目前为止我在这里看过，但没有反向地理编码我可以在CloudKit存储的位置。 
 
 这是我的模特： 
 
class Peek: CloudKitSyncable {

    static let kType = "Peek"
    static let kPhotoData = "photoData"
    static let kTimeStamp = "timestamp"
    static let kTitle = "title"
    static let kText = "text"
    static let kLocation = "location"
    static let kCity = "city"

    let title: String
    let text: String
    let photoData: Data?
    let timestamp: Date
    var location: CLLocation
    var comments: [Comment]
    var photo: UIImage? {

        guard let photoData = self.photoData else { return nil }
        return UIImage(data: photoData)
    }

    init(title: String, timestamp: Date = Date(), text: String, photoData: Data?, comments: [Comment] = [], location: CLLocation) {
        self.title = title
        self.timestamp = timestamp
        self.text = text
        self.photoData = photoData
        self.comments = comments
        self.location = location
    }

    var recordType: String {
        return Peek.kType
    }

    var cloudKitRecordID: CKRecordID?

    convenience required init?(record: CKRecord) {

        guard let timestamp = record.creationDate,
            let photoAsset = record[Peek.kPhotoData] as? CKAsset,
            let title = record[Peek.kTitle] as? String,
            let text = record[Peek.kText] as? String,
        let location = record[Peek.kLocation] as? CLLocation else { return nil }
        let photoData = try? Data(contentsOf: photoAsset.fileURL)
        self.init(title: title, timestamp: timestamp, text: text, photoData: photoData, location: location)
        cloudKitRecordID = record.recordID
    }

    fileprivate var temporaryPhotoURL: URL {
        let temporaryDirectory = NSTemporaryDirectory()
        let temporaryDirectoryURL = URL(fileURLWithPath: temporaryDirectory)
        let fileURL = temporaryDirectoryURL.appendingPathComponent(UUID().uuidString).appendingPathExtension("jpg")

        try? photoData?.write(to: fileURL, options: .atomic)

        return fileURL
    }

}
extension CKRecord {

    convenience init(_ peek: Peek) {
        let recordID = CKRecordID(recordName: UUID().uuidString)
        self.init(recordType: peek.recordType, recordID: recordID)

        self[Peek.kTitle] = peek.title as String? as CKRecordValue?
        self[Peek.kText] = peek.text as String? as CKRecordValue?
        self[Peek.kTimeStamp] = peek.timestamp as CKRecordValue?
        self[Peek.kLocation] = peek.location as CKRecordValue?
        self[Peek.kPhotoData] = CKAsset(fileURL: peek.temporaryPhotoURL)
    }
}
 
 我也有一个LocationManager文件： 
 
class LocationManager: NSObject {

    static let sharedInstance = LocationManager()

    override init() {
        super.init()
        locationManager.delegate = self
    }

    var locationManager = CLLocationManager()
    var currentLocation: CLLocation?

    func requestCurrentLocation() {
        locationManager.requestLocation()
    }
}

extension LocationManager: CLLocationManagerDelegate {

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        currentLocation = locations.first
    }

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("error: \(error.localizedDescription)")
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
            locationManager.requestLocation()
        }
    }
}

I am trying to figure out how to reverse geocode a CLLocation stored in CloudKit. I have the location stored in a record and I know it stores as latitude and longitude. Here's my record. The latitude and longitude appear I just took them out for now. However I want to be able to make the location user-readable, so AKA reverse geocode it, to get the city and state. And I've looked on here so far but nothing on reverse geocoding the location I can store in CloudKit.
 
Here is my model:
 
class Peek: CloudKitSyncable {

    static let kType = "Peek"
    static let kPhotoData = "photoData"
    static let kTimeStamp = "timestamp"
    static let kTitle = "title"
    static let kText = "text"
    static let kLocation = "location"
    static let kCity = "city"

    let title: String
    let text: String
    let photoData: Data?
    let timestamp: Date
    var location: CLLocation
    var comments: [Comment]
    var photo: UIImage? {

        guard let photoData = self.photoData else { return nil }
        return UIImage(data: photoData)
    }

    init(title: String, timestamp: Date = Date(), text: String, photoData: Data?, comments: [Comment] = [], location: CLLocation) {
        self.title = title
        self.timestamp = timestamp
        self.text = text
        self.photoData = photoData
        self.comments = comments
        self.location = location
    }

    var recordType: String {
        return Peek.kType
    }

    var cloudKitRecordID: CKRecordID?

    convenience required init?(record: CKRecord) {

        guard let timestamp = record.creationDate,
            let photoAsset = record[Peek.kPhotoData] as? CKAsset,
            let title = record[Peek.kTitle] as? String,
            let text = record[Peek.kText] as? String,
        let location = record[Peek.kLocation] as? CLLocation else { return nil }
        let photoData = try? Data(contentsOf: photoAsset.fileURL)
        self.init(title: title, timestamp: timestamp, text: text, photoData: photoData, location: location)
        cloudKitRecordID = record.recordID
    }

    fileprivate var temporaryPhotoURL: URL {
        let temporaryDirectory = NSTemporaryDirectory()
        let temporaryDirectoryURL = URL(fileURLWithPath: temporaryDirectory)
        let fileURL = temporaryDirectoryURL.appendingPathComponent(UUID().uuidString).appendingPathExtension("jpg")

        try? photoData?.write(to: fileURL, options: .atomic)

        return fileURL
    }

}
extension CKRecord {

    convenience init(_ peek: Peek) {
        let recordID = CKRecordID(recordName: UUID().uuidString)
        self.init(recordType: peek.recordType, recordID: recordID)

        self[Peek.kTitle] = peek.title as String? as CKRecordValue?
        self[Peek.kText] = peek.text as String? as CKRecordValue?
        self[Peek.kTimeStamp] = peek.timestamp as CKRecordValue?
        self[Peek.kLocation] = peek.location as CKRecordValue?
        self[Peek.kPhotoData] = CKAsset(fileURL: peek.temporaryPhotoURL)
    }
}
 
I also have a LocationManager file as well:
 
class LocationManager: NSObject {

    static let sharedInstance = LocationManager()

    override init() {
        super.init()
        locationManager.delegate = self
    }

    var locationManager = CLLocationManager()
    var currentLocation: CLLocation?

    func requestCurrentLocation() {
        locationManager.requestLocation()
    }
}

extension LocationManager: CLLocationManagerDelegate {

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        currentLocation = locations.first
    }

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("error: \(error.localizedDescription)")
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
            locationManager.requestLocation()
        }
    }
}
