}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// get a reference to the second view controller
if segue.identifier == "viewPlaceSegu" {
if let secondViewController = segue.destinationViewController as? TableViewPlace {
// set a variable in the second view controller with the String to pass
print(countryArry)
secondViewController.tnt = countryArry
}
}
}
}
when I print(countryArry) return nil why ??
Can someone help me or give me a better solution?

Answer 1

You are creating a Post object with this line :
let countryPlace = Post(userid: post["userId"] as! Int, title: post["title"] as! String)
And you are trying to pass to your tableview this Post object to your tnt variable which is a ViewController class, this is why you've got the first error :
secondViewController.tnt = Country
Then, if you want to add your string country to your mutable array you have to do :
if let title = tnt.title {
Country.append(title)
}
