Description

Learn to create with SwiftUI/iOS 16. This course illustrates many features in iOS 16 development using the SwiftUI programming language, covering the basics (Stacks, Forms, Lists, ForEach, Buttons, Sliders, Pickers, Color Pickers, Scroll Views, Sheets, state, binding, and animations) and we create an Emoji Quote app using SwiftUI.

SwiftUI creates user interfaces for any Apple platform and helps create beautiful and dynamic apps fast. SwiftUI helps build functional apps across all Apple platforms with surprisingly little code. The course begins with a brief introduction to the text, modifiers, stacks, state variables, and animations and then advances to cover ForEach views, sheets, pickers, sliders, toggle switches, scroll views, buttons, etc. We will move to develop the main app and learn to create an app icon based on Pexels Figma. We will learn to disassemble an SVG image and convert it to PNG using Pexel Figma and Shape and Path to create a speech bubble and add text. We will create a color palette to support light and dark modes and develop a model of a quote-based app on a free quote API, part of the MVVM (Model, View-Model, View design pattern). When tapped, we will test the emoji to generate a new quote and copy the image to the clipboard with a long press. We will create image grids using an iPad/iPhone and create a share sheet to customize the images/quotes; change text color/size or image size, share or save it, and test the app's functionality on a simulator. Upon completion, we can develop an Emoji Quote app using SwiftUI/iOS 16. The course aims for succinct yet fairly comprehensive SwiftUI/iOS 16 development.

9. The Quote View Model

This is a continuation of the previous video about the quotable API. Here, we will create the view model, connecting the actual view and the data model we created.

10. The Emoji Ninja Can Quote

In this video, you will learn to add the bubble to the ninja emoji and test the ninja to display a quote when it functions. We will create a button to activate the ninja to display a random quote.

11. Create Context Menu to Copy to Clipboard

Here, we will understand how to create image constants and a context menu. We will access the images we have chosen for the app, create a grid, and iterate through the images.

12. Import Images and GridImagesView

Let's learn to import images and create a dedicated SwiftUI view called the "GridImagesView" and add the parameters to the SwiftUI view to adjust the images and display.

13. The Images View

Let's understand how to change the image preview in the image view. We will use the repeat function to define the number of times the image view appears and add scroll views.

14. Completing the GridImagesView

In this video, we will understand how to change the image view. You will learn to create partial views of the images and also be able to scale the text.

15. Updating the Image View

This video demonstrates how we can update the image view. We will use binding variables defining the image, color, and size. We will also adjust the image view based on the device that the app will run.
