Missing argument for parameter #1 in function call

I'm having trouble returning a variable from a 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() seems to be a class method so you should prepend class to the method signature.

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

Besides, please note that ; at the end of each expression/assignment is totally optional so you can simply skip it.

Since your method doesn't return an implicitly unwrapped optional, you should also delete ! too.

var test: NSString =  SearchVC.dd()
