Parse SDK 1.7.1 not working in Xcode 6.3

My code worked fine in Xcode 6.2. After the update to Xcode 6.3 I had some Nullabilty Errors.

I could solve these errors after I downloaded the Parse SDK 1.7.1. So I deleted the old Parse framework files in my project and pasted the new ones into it. Additional I convert my code to the latest swift syntax "Edit/Convert/latest swift syntax". Now I haven't problems with Nullabilty Errors but several others. In my project I have a simple Tableviewcontroller with the following code:

import UIKit

class HaendlerTableViewController: PFQueryTableViewController {
// Initialise the PFQueryTable tableview
override init!(style: UITableViewStyle, className: String!) {  //1. Falialbe initialize init/style:className:)' cannot override a non-failable initializer
    super.init(style: style, className: className)
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

    // Configure the PFQueryTableView
    self.parseClassName = "Haendler"
    self.textKey = "name"
    self.pullToRefreshEnabled = true
    self.paginationEnabled = false
}

// Define the query that will provide the data for the table view
override func queryForTable() -> PFQuery! {  //2. Ovverriding method with selector queryForTable has incompatitble typ () -> PFQuery
    var query = PFQuery(className: "Haendler")
    query.orderByAscending("name")
    return query
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject) -> PFTableViewCell { //3. Ovverriding method with selector 'tableView:cellForRowAtindexPath:object:' has incompatible type '(UITableView, NSIndexPath, PFObject) -> PFTableViewCell

    var cell = tableView.dequeueReusableCellWithIdentifier("HaendlerCell") as! HaendlerCell!
    if cell == nil {
        cell = HaendlerCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
    }

    // Extract values from the PFObject to display in the table cell
    cell.haendlerName.text = object["name"] as! String!

    var thumbnail = object["logo"] as! PFFile
    var initialThumbnail = UIImage(named: "haendler")
    cell.haendlerBild.image = initialThumbnail
    cell.haendlerBild.file = thumbnail
    cell.haendlerBild.loadInBackground()

    return cell
}


override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {


    var detailScene = segue.destinationViewController as! HaendlerDetailViewController

    // Pass the selected object to the destination view controller.
    if let indexPath = self.tableView.indexPathForSelectedRow() {
        let row = Int(indexPath.row)
        detailScene.currentObject = objects[row] as? PFObject //4. Could not find an overload for 'subscript' that accepts the supplied agruments
    }
}

}

I wrote the errors in a comment on the right side of the code and below.

  1. Falialbe initialize init/style:className:)' cannot override a non-failable initializer
  2. Ovverriding method with selector queryForTable has incompatitble typ () -> PFQuery
  3. Ovverriding method with selector 'tableView:cellForRowAtindexPath:object:' has incompatible type '(UITableView, NSIndexPath, PFObject) -> PFTableViewCell
  4. Could not find an overload for 'subscript' that accepts the supplied agruments

I have the same errors when I make a new Swift project from the Parse Quickstart and add one Tableviewcontroller. In my old project was an objective-C bridging header which one I deleted because I had the oppurtunity to add the Parse SDK 1.7.1 directly in my Swift project.

Now I need help because I don't see what I have to change..

PS: Sorry for the mix of German and English code I'll adjust it once the project is running again

Had the same issues.

To solve the first initialise issue remove the '!' after 'override init'. Should look like this:

// Initialise the PFQueryTable tableview
override init(style: UITableViewStyle, className: String!) {  //1. Falialbe initialize init/style:className:)' cannot override a non-failable initializer
    super.init(style: style, className: className)
}

Do the same for the 2nd error after 'PFQuery'

override func queryForTable() -> PFQuery {

Hope its helpful. Since the latest update unwrapping elements usually needs to be revised for possible errors.

I had the same issue as I just updated Xcode to 6.3 about 20 minutes ago.

For your 2nd error, remove the '!' after 'PFQuery'. So it should now look like.. override func queryForTable() -> PFQuery {

This solved my problem in regards to that specific error.

I never used an init method as you did in your first error, but try removing it and see what you get. My PFQueryTableViewController works fine without it.
