Transfer variables from one class to another class for table view - ios

Question

I am trying to transfer variables from one class into a table view class as follows (excellent code for the table view class).
I get the following error in class SecondViewController:
xnyCats = catRet.mainCats() throws an error Expected Declaration
How do I get class SecondViewController to inherit xnyCats from class XnYCategories?
import UIKit
import Foundation
class XnYCategories {
var catsXny: [String]
init(catsXny: [String]) {
self.catsXny = catsXny
}
func mainCats() -> [String] {
var catsXny = ["Sport", "Recreation", "Travel", "Cultural", "Music"]
return catsXny
}
}
let catRet = XnYCategories(catsXny: [""])
var xnyCats = [""]
xnyCats = catRet.mainCats()
xnyCats[1]
import UIKit
class SecondViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var tableView: UITableView!
#IBAction func displayTapped(sender : AnyObject) {
}
let textCellIdentifier = "TextCell"
let catRet = XnYCategories(catsXny: [""])
var xnyCats = [""]
xnyCats = catRet.mainCats() //throws an error 'Expected Declaration'
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return xnyCats.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = xnyCats[row]
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
let row = indexPath.row
println(xnyCats[row] + String(row))
}
}

By checking your code i find out that you are not able to call the mainCats()function from other class so there are different ways to call a function
1: Create the class object and call the function for example
class Demo {
func display() {
println("Hello")
}
}
var d = Demo()
d.display()
2: Declare class function and call it. for example
class Demo {
class func display() {
println("Hello")
}
}
Demo.display()
Now make the following modification in your code and u get the result
class XnYCategories {
var catsXny: [String]
init (catsXny: [String]){
self.catsXny = catsXny
}
class func mainCats() -> [String] {
var catsXny = ["Sport", "Recreation", "Travel", "Cultural", "Music"]
return catsXny
}
}
let catRet = XnYCategories.mainCats()
println(catRet)
