Swift errors when handling data from server, json

Question

I converted my project from Objective-C to Swift but I ran into some errors.

First set of errors:

public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {



    let CellIdentifier = "Cell"

    var cell = tableView.dequeueReusableCell(withIdentifier: CellIdentifier)!



    if cell != cell {

        cell = CustomCell(style: UITableViewCellStyle.default, reuseIdentifier: CellIdentifier)

    }



    // Configuring the cell

    Data * dataObject



    if !isFiltered {

        if indexPath.section == 0 {

            dataObject = followedArray[indexPath.row]

            cell.populateCell(dataObject, isFollowed: true, indexPath: indexPath, parentView: self)

        }

        else if indexPath.section == 1 {

            dataObject = dataArray[indexPath.row]

            cell.populateCell(dataObject, isFollowed: false, indexPath: indexPath, parentView: self)

        }

    }

    else {

        dataObject = filteredArray[indexPath.row]

        cell.populateCell(dataObject, isFollowed: false, indexPath: indexPath, parentView: self)

    }

    return cell

}

Here is a picture of the errors:

Here is the Data NSObject Class

class Data: NSObject {



//Strings

var dataName: String?

var dataID: String?

var dataStatus1: String?

var dataStatus2: String?

var dataURL: String?



override init() {



}



//Converting Strings into Objects



init(dataName dName: String,

     andDataStatus1 dStatus1: String,

     andDataStatus2 dStatus2: String,

     andDataURL dURL: String,

     andDataID dID: String)

{



    super.init()



    self.dataName = dName

    self.dataStatus1 = dStatus1

    self.dataStatus2 = dStatus2

    self.dataURL = dURL

    self.dataID = dID



 }



}

Thats the first set of errors.

Now the Second Set of errors

This code is for retrieving the data from the server

// Retrieving Data from Server

func retrieveData() {



    let url: NSURL = NSURL(string: getDataURL)!

    let data: NSData = NSData(contentsOfURL: url)

    jsonArray = NSJSONSerialization.JSONObjectWithData(data, options: kNilOptions, error: nil)



    // Setting up data array

    dataArray = NSMutableArray()



    // Looping through jsonArray

    for i in 0..<jsonArray.count {

        // Create Data Object

        let dID: String = jsonArray[i]["id"] as! String!

        let dName: String = jsonArray[i]["dataName"]

        let dStatus1: String = jsonArray[i]["dataStatus1"]

        let dStatus2: String = jsonArray[i]["dataStatus2"]

        let dURL: String = jsonArray[i]["dataURL"]



        // Add Data Objects to Data Array

        dataArray.append(Data(dataname: dName, andDataStatus1: dStatus1, andDataStatus2: dStatus2, andDataURL: dURL, andDataID: dID))

    }



    self.myTableView.reloadData()

}

Here is a picture of the errors:

I tried renaming some of the code from the errors but that just ended with more errors so I left it as originally converted. I'm learning Swift but these are deeper side of coding but in fixing it, I will be learning a lot more. Thank you for any help!

You did not convert to Swift very well at all. And the error log basically explains everything that is wrong very well.

Line 109

var dataObject: Data

Line 227

jsonArray = JSONSerialization.JSONObjectWithData(data, options: nil, error: nil)

Line 230

var dataArray = []

Line 235+

let dID: String = jsonArray[i].objectForKey("id") as! String!
...
let dURL: NSURL = jsonArray[i].objectForKey("dataURL") as! NSURL

Line 242

dataArray.append(Data(dataname: dName, andDataStatus1: dStatus1, andDataStatus2: dStatus2, andDataURL: dURL, andDataID: dID))
