Swift - UITextField Programmatically Cannot enter text

Question

I'm new to Swift programming, I'm trying to build an app with UITextField in it, But I'm having a problem, I created an UITextField programmatically but it seems like I cannot enter a text in it. Here's my viewDidLoad

Code:

override func viewDidLoad() {
    super.viewDidLoad()
    self.tableView = UITableView(frame: self.tableView.frame, style: .Grouped)

    self.groupInfoView.frame = CGRectMake(0, 44, self.view.frame.width, 100)
    self.groupInfoView.backgroundColor = UIColor.orangeColor()
    self.groupInfoView.userInteractionEnabled = true



    groupImg.frame = CGRectMake(10, 50, 40, 40)
    groupImg.layer.cornerRadius = 5
    groupImg.layer.masksToBounds = true
    groupImg.image = UIImage(named: "group-def-img")

    groupTitle = UITextField.init(frame:CGRectMake(groupImg.frame.maxX + 5, 50, self.groupInfoView.frame.width-65, 40))
    groupTitle.backgroundColor = UIColor.whiteColor()
    groupTitle.layer.cornerRadius = 5
    groupTitle.layer.masksToBounds = true
    groupTitle.placeholder = "Enter Group Title"
    groupTitle.textColor = UIColor.orangeColor()
    groupTitle.textAlignment = .Center
    groupTitle.font = UIFont(name: "HelveticaNeue-Light", size: 18)
    groupTitle.autocorrectionType = UITextAutocorrectionType.No
    groupTitle.keyboardType = UIKeyboardType.Default
    groupTitle.returnKeyType = UIReturnKeyType.Done
    groupTitle.clearButtonMode = UITextFieldViewMode.WhileEditing;
    groupTitle.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
    groupTitle.enabled = true
    groupTitle.userInteractionEnabled = true
    groupTitle.delegate = self
    groupTitle.text = "asda"


    recipientLabel.frame = CGRectMake(5, 0, self.view.frame.width - 20, 40)
    recipientLabel.font = UIFont(name: "HelveticaNeue-Light", size: 15)
    recipientLabel.numberOfLines = 3
    recipientLabel.textColor = UIColor.orangeColor()
    recipientLabel.backgroundColor = UIColor.whiteColor()
    recipientLabel.center.x = self.view.center.x
    recipientLabel.layer.cornerRadius = 7
    recipientLabel.layer.masksToBounds = true
    recipientLabel.text = " To:"

    self.groupInfoView.addSubview(groupTitle)
    self.groupInfoView.addSubview(recipientLabel)
    self.groupInfoView.addSubview(groupImg)
    searchBar.delegate = self
    self.titleLabel.text = "New Group Message"
    navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
    navigationController?.navigationBar.shadowImage = UIImage()
    self.navigationController?.tabBarController?.tabBar.barStyle = .Black
    self.navigationController!.navigationBar.translucent = false
    self.navigationController!.navigationBar.barTintColor = UIColor.orangeColor()

    tableView.separatorInset = UIEdgeInsets(top: 0, left: 65, bottom: 0, right: 0)

    tableView.registerClass(UserCell.self, forCellReuseIdentifier: cellId)

    navigationItem.leftBarButtonItem = UIBarButtonItem(title: "Cancel", style: .Plain, target: self, action: #selector(handleCancel))

    navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Done", style: .Done, target: self, action: #selector(handleDone))


    fetchUser()
    self.tableView.allowsMultipleSelection = true

    if let navigationBar = self.navigationController?.navigationBar {

        let firstFrame = CGRectMake(0, -5, (self.navigationController?.navigationBar.frame.width)!, 40)
        let secondFrame = CGRectMake(0, 17, (self.navigationController?.navigationBar.frame.width)!, 30)

        titleLabel.frame = firstFrame
        titleLabel.textColor = UIColor.whiteColor()
        titleLabel.font = UIFont(name: "HelveticaNeue-SemiBold", size: 18)
        titleLabel.textAlignment = .Center


        countLabel.textColor = UIColor.whiteColor()
        countLabel.font = UIFont(name: "HelveticaNeue-Light", size: 13)
        countLabel.frame = secondFrame
        countLabel.textAlignment = .Center

        navigationBar.addSubview(groupInfoView)
        navigationBar.addSubview(titleLabel)
        navigationBar.addSubview(countLabel)

    }

And this is my references:

Code:

var titleLabel = UILabel()
var countLabel = UILabel()
var recipientLabel = UILabel()
var groupImg = UIImageView()
var groupTitle: UITextField = UITextField()
var groupInfoView = UIView()

Declare its globally so you can access it anywhere. and declare its delegates UITextFieldDelegate Headerimageview is my heartimage and HeaderView is my simple header view.

@IBOutlet var Headerimageview: UIImageView!
@IBOutlet var HeaderView: UIView!
var groupTitle : UITextField = UITextField()

In viewDidLoad()

groupTitle = UITextField.init(frame: CGRectMake(Headerimageview.frame.size.width + 25, 5, self.view.frame.width-85, 40))
groupTitle.backgroundColor = UIColor.whiteColor()
groupTitle.layer.cornerRadius = 5
groupTitle.layer.borderWidth = 1.0
groupTitle.layer.borderColor = UIColor.brownColor().CGColor
groupTitle.layer.masksToBounds = true
groupTitle.placeholder = "Enter Group Title"
groupTitle.textColor = UIColor.orangeColor()
groupTitle.textAlignment = .Center
groupTitle.font = UIFont(name: "HelveticaNeue-Light", size: 18)
groupTitle.autocorrectionType = UITextAutocorrectionType.No
groupTitle.keyboardType = UIKeyboardType.Default
groupTitle.returnKeyType = UIReturnKeyType.Done
groupTitle.clearButtonMode = UITextFieldViewMode.WhileEditing
groupTitle.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
groupTitle.enabled = true
groupTitle.userInteractionEnabled = true
groupTitle.delegate = self
self.HeaderView.addSubview(groupTitle)

Output :

TextField should begin editing method called

TextField did begin editing method called

While entering the characters this method gets called

While entering the characters this method gets called

While entering the characters this method gets called

TextField should return method called

TextField should snd editing method called

TextField did end editing method called

Update your this code with mine one...

 groupTitle = UITextField.init(frame:CGRectMake(groupImg.frame.maxX + 5, 25, self.groupInfoView.frame.width-65, 40))
  groupTitle = UITextField.init(frame: CGRectMake(groupImg.frame.size.width + 25, 25, self.view.frame.width-85, 40))
  self.groupInfoView.addSubview(groupTitle)
  self.groupInfoView.addSubview(groupImg)
  self.view.addSubview(groupInfoView)
