Swift：无法将'() -> Bool'类型的值转换为预期的参数类型'PFObject'

在整体方案中，我试图比较用户从tableview中选择的多个选项，并将它们与我的Parse数据库进行比较 . 所以我的问题是双重的1.我当前的代码是否以正确的方式进行？ 2.如何将值类型Bool转换为参数类型PFObject？

无法将类型'（） - > Bool'的值转换为预期的参数类型'PFObject'

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


    if segue.identifier == "showResults" {

        // Get reference to destination view controller
        let destination = segue.destinationViewController as! CollectionViewController

        if let selectedItem = tableView.indexPathsForSelectedRows{

            for var i = 0; i < selectedItem.count; ++i {

                var currentPath = selectedItem[i] as NSIndexPath
                var cell = tableView.cellForRowAtIndexPath(currentPath)

                if let cell = cell {

                    //add major(s) selected to data variable in collectionview as type text(String)
                    destination.data.append(cell.textLabel!.text!)

                }

让imagesQuery = PFQuery（className：“CollegeImages”）imagesQuery.selectKeys（[“name”]）imagesQuery.findObjectsInBackgroundWithBlock（{（objects：[PFObject]？，error：NSError？）in if if error == nil {if let returnedobjects = objects {// objects数组不是nil //循环遍历数组以获取返回对象中的对象的每个对象{print（object [“name”] as！String）}}

}
                })

                let majorSelected:String = (cell?.textLabel!.text!)!
                let query = PFQuery(className:"CollegeMajors")
                query.selectKeys(["Major"])
                query.findObjectsInBackgroundWithBlock ({
                    (objects: [PFObject]?, error: NSError?) in

                    if error == nil {
                        // The find succeeded.
                        print("Successfully retrieved \(objects!.count) majors.", terminator: "")
                        // Do something with the found objects
                        if let returnedobjects = objects {
                            if returnedobjects.contains ({($0["Major"] as? String)! == majorSelected}) && query.selectKeys(["College Name"]) ==  imagesQuery.selectKeys(["name"]) {
                                print("your in!") // transition to the new screen

                            }
                            else {
                                print("your out.") // do whatever
                            }
                        }
                    } else {
                        // Log details of the failure
                        print("Error: \(error!) \(error!.userInfo)", terminator: "")
                    }
                })
            }

        }


    }






}


override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    //Keep track of which major(s) the user selected
    let path = tableView.indexPathForSelectedRow!
    if let cell = tableView.cellForRowAtIndexPath(indexPath){


        //Trigger the segue to go to the collection view
        self.performSegueWithIdentifier("showResults", sender: self)
    }
