Missing argument for parameter # 1 when calling the function

I'm having trouble returning a variable from func

:

class SearchVC: UITableViewController, UISearchResultsUpdating, UISearchControllerDelegate {

    var test: NSString = SearchVC.dd()!

    func dd() -> NSString {
        let testing: NSString = "d"
        return testing
    }
}

Error: missing argument for parameter #1 in call

dd()

is represented by a class method, so you must add class

to the method signature.

class func dd() -> NSString {
    ...
}

Also, note that ;

at the end of each expression / assignment is completely optional, so you can just skip it.



Since your method does not return implicitly unwrapped optional

, you must delete as well !

.

var test: NSString =  SearchVC.dd()
