Swift 3 Послать изображение CloudKit с CKAsset

Question

NB: Это не повторение вопроса, я посмотрел на другие решения, но ни один из них работает в Swift 3, но они делают в Swift 2.

Мне нужно, чтобы получить образ из библиотеки фотографий с UIImagePickerController, который работает отлично, то мне нужно сделать это, чтобы каким-то образом сохранить это в общедоступной записи в CloudKit, я очень открыт относительно того, как это делается. Пожалуйста, по возможности, уточните, что мне нужно изменить/добавить и где.

Я предоставил весь файл контроллера для просмотра, чтобы быть уверенным.

Укажите простой способ сохранить изображение как CKAsset с помощью CloudKit. Обязательно измените имя для своей записи и имя поля для актива при настройке записи.

let documentsDirectoryPath:NSString = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString 
var imageURL: URL! 
let tempImageName = "Image2.jpg" 


func saveImage(_ image: UIImage?) { 

    // Create a CKRecord 
    let newRecord:CKRecord = CKRecord(recordType: "<INSERT_RECORD_NAME") 

    if let image = image { 

     let imageData:Data = UIImageJPEGRepresentation(image, 1.0)! 
     let path:String = self.documentsDirectoryPath.appendingPathComponent(self.tempImageName) 
     try? UIImageJPEGRepresentation(image, 1.0)!.write(to: URL(fileURLWithPath: path), options: [.atomic]) 
     self.imageURL = URL(fileURLWithPath: path) 
     try? imageData.write(to: self.imageURL, options: [.atomic]) 

     let File:CKAsset? = CKAsset(fileURL: URL(fileURLWithPath: path)) 
     newRecord.setObject(File, forKey: "<INSERT_RECORD_ASSET_FIELD_NAME") 
    } 

    if let database = self.publicDatabase { 

     database.save(newRecord, completionHandler: { (record:CKRecord?, error:Error?) in 

      // Check if there was an error 
      if error != nil { 
       NSLog((error?.localizedDescription)!) 
      } 
      else if let record = record { 

       // Do whatever you want with the record, but image record was saved, asset should be saved. 

      } 


     }) 


    } 


} 

Если вы не можете сделать формат JPEG, и нужно сохранить как .png вы можете заменить раздел UIImageJPEGRepresentation с этим:

let imageData:Data = UIImagePNGRepresentation(image)! 
try? UIImagePNGRepresentation(image)!.write(to: URL(fileURLWithPath: path), options: [.atomic]) 

И сделать что-то вроде tempImageNamelet tempImageName = "Image2.png"

Надежда это помогает
