SwiftUI UIControls

Let's see what UIControls we have to design UI in SwiftUI.

UIKit                           SwiftUI

UIViewController View
UITableViewController List
UINavigationViewController NavigationView
UITabViewController TabView
UIAlertViewController Alert
UILabel         Text
UITextField TextField
UIStackView 1. VStack 2. HStack 3. ZStack
UIScrollView ScrollView
UIImageView Image
UIPickerView Picker
UIButton         Button
UIDatePicker DatePicker
UISlider         Slider
UIStepper Stepper
UISwitch         Toggle


I know this is not a complete list; I am too exploring it.



ContentView.swift is the file where we are going to code. By default we get a Text as Hello, World!

Let's see what this file actually means and what it does.
So here we have two structures:
  1.  ContentView struct - This is the place to code or design.
  2.  ContentView_Previews struct - From here your canvas renders your code.

1. ContentView struct - Here we are returning a Text as some view. some view means any view here, we can return a Text, TextField, NavigationView, List, etc.
Now you will ask what I wish to add multiple Text?
For this you need to club it using either List, Group, VStack, Hstack, etc.

2. ContentView_Previews struct - Here too we are returning some view, but now we are returning the complete ContentView() as some view.

In some situations we need to add or remove rows dynamically from a UITableView. We can achieve it very easily, just got through the tutorial : 1. Create a new project. 2.  In AppDelegate implementation file create an object of UINavigationController (navController here). 3. Add object of UIViewController (viewController here) as rootviewcontroller of UINavigationController. 4. In ViewController.xib nib file take a UITableView. 5. Set delegate and datasource of UITableView to File's Owner. 6. Create an IBOutlet to UITableView (tableViewForScreen here) in ViewControler.h header file. 7. Declare an object of NSMutableArray (arrayForTableContent here) in ViewControler.h header file. 8. In ViewController.m file in viewDidLoad method set edit and add buttons as leftBarButtonItem and rightBarButtonItem respectively. 9. Initialize arrayForTableContent array and add objects to it.
