.swipeActions()

Previously, we List rows were limited to only 1 swipe action - swipe to delete. Now, however, we can totally customize these rows and add a whole bunch of buttons to them. We will implement a few different variations of list row actions, each with

@FocusState

In practice, this will most often be associated with users clicking on TextFields. In this video, we will first learn what Focus State is and then review a few real-world implementations! As a bonus, we will also check out Apple's documentation on

.badge

TextSelection()

This is great for chat apps or any content-based app where users might want to share some text with a friend. Sharing is not only a great feature for your users, but will help drive organic growth as users share with others.

System Material

These System Materials are very commonly used as backgrounds for a subtle, yet professional look to your apps. As you'll see, the colors are not totally opaque and allow some natural color to bleed through.

.buttonStyle & .controlSize

@AppStorage

We can save the small piece of data when the app is closed.Once we close the app on HomeView, we will never see the OnboardingView again.Important: @AppStorage writes your data to UserDefaults, which is not secure storage. As a result, you should

@EnvironmentObject

The @EnvironmentObject is a super-useful property wrapper that lets us put an observable object into the environment of our SwiftUI application. By doing this, all of these views in the view hierarchy will then have access to this object. This is

@StateObject & @ObservableObject

Why is important?→ @StateObject → INIT→ @ObservedObejct → SubviewToday, I learned about ObservableObject and StateObject. These are property wrappers that observe other classes and update them in the view.Whenever the view is updated and reloaded,

Custom model

Custom data types are frequently needed in our applications. They allow us to incorporate multiple data points into a single model. For instance, a User's data may need to encompass more than just their name. By creating a custom data type, we can

Tap gesture

The .onTapGesture modifier functions much like a button and can even be customized to recognize multiple taps instead of just one (double-tap, triple-tap, etc.).count: number of taps to perform the actionjust like instagram.

SAFE CODING: if let & guard

In Swift, variables can be declared as optional using the '?' symbol, indicating they may be nil. To safely check and unwrap these optional variables, 'if let' and 'guard' statements are recommended. These methods are safer than explicitly

onAppear & onDisappear

#modifierThe onAppear and onDisappear modifiers are extremely convenient methods that let us call functions when specific components appear or disappear from the screen. These are often used for managing animations and loading data in SwiftUI

NavigationStack & NavigationLink

.sheet() vs .transition() vs .animation

Previous .transition() note, we only used a single button to toggle the screen.This time we will use @Binding and other button on the new screen to toggle.For your information, it appears really impressive.

.sheet() & .fullScreenCover()

We didn’t assign anything on that “X” button, so we can’t go back to the screen.Someone told me, "you should learn AI instead of VisionOS."However, I'm interested in building experiences, which is why I'm focusing on MR.

Transition

Use .transition to animate an object's entry and exit.❓When should we use .animation and .transition?💛 Playing with the .asymmetric transition effect can be fun.🫥 So, which one do we use the most?#visionOS #applevisionpro #swiftUI #appdevelopment

Adding Animation

2023-12-29 In SwiftUI, animations can be added using withAnimation(). A button and a rounded rectangle can be created, with a boolean variable isAnimated used to change the value of elements. The withAnimation() function provides animation features
