Declarative vs Imperative Programming
01
Declarative vs Imperative Programming
The core difference between the term imperative and declarative. Now back to UI programming. Imperative UI programming requires developers to write detailed instructions to layout the UI and
control its states. Conversely, declarative UI programming lets developers describe how the UI looks like and what you want to do when a state changes.

No more Interface Builder and Auto Layout
With SwiftUI, Interface Builder and storyboards area unit utterly gone. It's replaced by a code editor and a
preview canvas just like the one shown in figure a pair of. You write
the code within the code editor. Xcode then renders the interface in
real time and show it within the canvas.
In Xcode eleven, you'll choose from SwiftUI and Storyboard to make
interface. If you have got designed associate app before, you will use
Interface Builder to layout UI on storyboard.

Layout User Interface with Stacks

Layout User Interface with Stacks
Stacks in SwiftUI is like stack views in UIKit. If you are combining horizontal and vertical views in stacks, you'll construct complicated user interfaces for your apps. For UIKit, it's unevitable to use auto layout in order to build interfaces that work all screen sizes. To some beginners, auto layout may be a difficult subject and arduous to be told. The great news is that you simply now not got to use auto layout in SwiftUI. Everything is stacks together with VStack, HStack, and ZStack.

Understanding ScrollView and Building a Carousel UI
Here, we are showing some features on ScrollView In swiftUI. SwiftUI provide us in build horizontal and vertical scrolling interface. Here we have few image in next slide for ScrollView functionality where you can see scroll view to mange card view UI. By using scrollview interface will manage
multiple data on single page.

Understanding State and Binding
05
Understanding State and Binding
In SwiftUI, it comes with many inbuilt options for state management. specifically, it introduces a property wrapper named @State. once you annotate a property with @State, SwiftUI automatically stores it somewhere in your application. what is additional, views that create use of that property
automatically hear the worth amendment of the property. once the state changes, SwiftUI can recompute those views and update the application's look.
Understanding State and Binding
In application development every developers need to implement state management. Let's take a example developers developing music player app. So when user click play button now button will change to a stop button. So in your implementation there must be some process to keep track application state and according that you know when to change that button.

Sample navigation interface for our demo projects
By using stacks, image, and text views, you should be able to create the UI. While I will go through the implementation.In this image, you can see complete UI sample.
