    let data = UIImageJPEGRepresentation(self.addedImage.image!, 0.5) 
    let metadata = StorageMetadata() 
    metadata.contentType = "image/jpeg" 

    let postId = "\(Auth.auth().currentUser!.uid)\(NSUUID().uuidString)" 
    // Create a reference to the file you want to upload 
    let imagePath = "postImages\(postId)/postPic.jpg" 

    storageRef.child(imagePath).putData(data!, metadata: metadata) { (metadata, error) in 
     if error == nil { 
      let postRef = self.databaseRef.child("posts").childByAutoId() 
      let post = Posts(postImageStringUrl: String (describing: metadata!.downloadURL()), content: descriptionTextView.text, postId: postId) 
      postRef.setValue(post.toAnyObject()) 
     }else{ 
      print(error.debugDescription) 
     } 
    } 
    //[Save Image] 

を

Here is the error I am getting

は '（文字列：文字列、コンテンツ：：文字列!, postId postImageStringUrl）' タイプの引数リストに型 '記事' の初期化子を呼び出すことはできません。ここに私のpostViewControllerがあります

import Foundation 
import Firebase 
import FirebaseDatabase 
import FirebaseStorage
 

struct Posts {
 

var postImageStringUrl: String! 
var department: String! 
var content: String! 
var username: String! 
var postId: String! 
var ref: DatabaseReference? 
var key: String! 


init(postImageStringUrl: String, department: String, content: String, username: String,postId: String, key: String = ""){ 

    self.postImageStringUrl = postImageStringUrl 
    self.department = department 
    self.content = content 
    self.username = username 
    self.postId = postId 
    self.key = key 
    self.ref = Database.database().reference() 


} 

init(snapshot: DataSnapshot){ 

    let snapshotValue = snapshot.value as! NSMutableDictionary 

    self.postImageStringUrl = snapshotValue["postImageStringUrl"] as! String 
    self.department = snapshotValue["department"] as! String 
    self.content = snapshotValue["content"] as! String 
    self.username = snapshotValue["username"] as! String 
    self.postId = snapshotValue["postId"] as! String 
    self.key = snapshot.key 
    self.ref = snapshot.ref 


} 

func toAnyObject() -> [String: AnyObject] { 

    return ["postImageStringUrl": postImageStringUrl as AnyObject, "department": department as AnyObject,"content": content as AnyObject,"username": username as AnyObject, "postId": postId as AnyObject] 
} 

}

すべてのヘルプは大歓迎されます

は

init(
    postImageStringUrl: String, 
    department: String,

    postId: String, 
    key: String = "")

let post = Posts(
      postImageStringUrl: String (describing: metadata!.downloadURL()), 
      content: descriptionTextView.text, 
      postId: postId) 

で初期化しようとしている表示されます初期化でいくつかのパラメータが欠落しています。部門、ユーザー名
