I know it may be the basic question but I am new to Swift.
Also, I have tried various solutions on SO but could not resolve the issue.
So if anyone can help me with my problem.

I have a custom UIVIEW class as follows:

class SearchTextFieldView: UIView, UITextFieldDelegate{

    public var searchText = UITextField()





        override init(frame: CGRect) {

            super.init(frame: frame)

            initializeUI()

        }





        required init?(coder aDecoder: NSCoder) {

            super.init(coder: aDecoder)

            initializeUI()

        }







        func initializeUI() {

            searchText.placeholder = "Enter model no"

            searchText.backgroundColor = UIColor.white

            searchText.textColor = UIColor.darkGray

            searchText.layer.cornerRadius = 5.0

            searchText.delegate=self

            self.addSubview(searchText)



        }



        override func layoutSubviews() {

            searchText.frame = CGRect(x: 20.0, y: 5.0, width: self.frame.size.width - 40,height : self.frame.size.height - 10)

        }

}

Now I want to set text to SearchText textfield from another class which is as follows:

override func viewDidLoad() {

        super.viewDidLoad()

        setupUI()

        // Do any additional setup after loading the view.

    }



    func setupUI() {



        let searchTextFieldView = SearchTextFieldView()

        self.view.addSubview(searchTextFieldView)    //adding view containing search box view at the top

        **searchTextFieldView.searchText.text = "My Text"**

    }

I am using Storyboard. Also, I can see the textfield with placeholder text.only problem is I can not set text to it.
Can anybody help. Whats wrong in my code.

It is needed to call searchTextFieldView.setNeedsDisplay(), this will in turn call override func draw(_ rect: CGRect) in class SearchTextFieldView.

Add override func draw(_ rect: CGRect) {} in SearchTextFieldView, and try setting searchText.text = <someValue> in draw(). You can use a String property in SearchTextFieldView, to get <someValue> from the client (one who is using SearchTextFieldView) class.

You are creating you view via SearchTextFieldView(), while you have 2 available initializers init(frame:) and init?(coder:).

If you change

let searchTextFieldView = SearchTextFieldView()

with

let searchTextFieldView = SearchTextFieldView(frame: CGRect(x: 50, y: 50, width: 100, height: 100))

you will see the text.

You are not setting frame to the view. Also you are not loading the .xib in the view class. It should be like:-

class SearchTextFieldView: UIView, UITextFieldDelegate{



    //MARK:- Initializer

    required init?(coder aDecoder: NSCoder) {

        super.init(coder: aDecoder)

        initialize(withFrame: self.bounds)

    }



    override init(frame : CGRect) {

        super.init(frame: frame)

        initialize(withFrame: frame)

    }



    //MARK: -  View Initializers

    func initialize(withFrame frame : CGRect) {



        Bundle.main.loadNibNamed("SearchTextFieldView", owner: self, options: nil)

        view.frame = frame

        view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

        self.addSubview(view)

        initializeUI()

    }

}

Now you can call the below code in view controller:-

    override func viewDidLoad() {

        super.viewDidLoad()

        setupUI()

       // Do any additional setup after loading the view.

    }



    func setupUI() {

        let searchTextFieldView = SearchTextFieldView(frame: ?*self.view.bounds)

        self.view.addSubview(searchTextFieldView)    

        //adding view containing search box view at the top

        searchTextFieldView.searchText.text = "My Text"

    }

Don't forget to create an xib with name "SearchTextFieldView.xib" as you are loading that nib in your initialize function.

Hope it helps :)

add frame for the searchTextFieldView inside setupUI() method. because the View got loaded on the view but its doesn't have a frame (x,y position, width and height). Change your UIViewController's colour to grey and u can see the your view loaded on the left corner (0,0). set frame size for the view that will solve this problem.
