Xcode pass Array by using segue

I made an array and put some values into it.

And by using segue,

I want to send the array to another view.

Here are codes.

----- View1 -----

override func viewDidLoad() {
    super.viewDidLoad()
    var receivedData: Array<String> = Array()
    receivedData.append("0.123")
    receivedData.append("0.190")
    receivedData.append("0.210")
    receivedData.append("0.213")
}


 @IBAction func graph(for segue: UIStoryboardSegue, sender: Any?) 
{

        if segue.destination is GraphViewController
        {
            let vc = segue.destination as? GraphViewController
            vc?.transferedData = receivedData
        }

}

----- View2 -----

var transferedData: Array<String> = Array()

But it doesn't work.

There are errors likes

"unrecognized selector sent to instance"

"Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: unrecognized selector sent to instance "

" libc++abi.dylib: terminating with uncaught exception of type NSException"

Help me to solve this problem.

Thanks for reading.

The reference of receivedData array will not accessible outside viewDidLoad() method which you have created. you have to declare it as a global array for that class, then you can access that array throughout your class.

Please declare receivedData outside of viewDidLoad() function. Please do following.

var receivedData: Array<String> = Array()

override func viewDidLoad() {
    super.viewDidLoad()

    receivedData.append("0.123")
    receivedData.append("0.190")
    receivedData.append("0.210")
    receivedData.append("0.213")
}
