Here’s an example and description for each command in SwiftUI:
1. Text:
Example:
“`swift
Text(“Hello, SwiftUI!”)
“`
Description: The `Text` view is used to display static text in your SwiftUI interface. It can be customized with various modifiers to change its font, color, alignment, and more.
2. Image:
Example:
“`swift
Image(“myImage”)
“`
Description: The `Image` view is used to display images in your SwiftUI interface. You can use either the name of an image asset in your project or a URL to an image on the internet.
3. Button:
Example:
“`swift
Button(action: {
// Action to perform when the button is tapped
}) {
Text(“Tap Me”)
}
“`
Description: The `Button` view is used to create interactive buttons in your SwiftUI interface. You can specify an action to perform when the button is tapped. The content of the button can be any SwiftUI view, such as `Text`, `Image`, or even a custom view.
4. NavigationView:
Example:
“`swift
NavigationView {
// Content of the navigation view
}
“`
Description: The `NavigationView` view is used to create a navigation hierarchy in your SwiftUI interface. It provides a navigation bar at the top of the screen and manages the navigation stack. You can push and pop views onto the stack to navigate between different screens.
5. List:
Example:
“`swift
List {
Text(“Item 1”)
Text(“Item 2”)
Text(“Item 3”)
}
“`
Description: The `List` view is used to display a scrollable list of views in your SwiftUI interface. It can contain any SwiftUI view as its content. You can also customize the appearance of the list, such as adding headers, footers, or separators.
6. ForEach:
Example:
“`swift
ForEach(items) { item in
Text(item.name)
}
“`
Description: The `ForEach` view is used to iterate over a collection of items and create a view for each item. It is commonly used with arrays or ranges to create multiple views dynamically. Each item in the collection is passed as a parameter to the closure, where you can create the view for that item.
7. TextField:
Example:
“`swift
TextField(“Enter your name”, text: $name)
“`
Description: The `TextField` view is used to create a text input field in your SwiftUI interface. It allows the user to enter text and binds the entered value to a `@State` or `@Binding` property. You can customize the appearance and behavior of the text field, such as adding a placeholder or secure entry.
8. Toggle:
Example:
“`swift
Toggle(“Enable Notifications”, isOn: $isNotificationsEnabled)
“`
Description: The `Toggle` view is used to create a switch-like control in your SwiftUI interface. It represents a binary state, such as on/off or true/false. You can bind the state of the toggle to a `@State` or `@Binding` property to track and control its value.
9. Alert:
Example:
“`swift
Alert(title: Text(“Error”), message: Text(“Something went wrong”), dismissButton: .default(Text(“OK”)))
“`
Description: The `Alert` view is used to display an alert dialog in your SwiftUI interface. It typically shows a title, a message, and one or more buttons for the user to dismiss the alert. You can customize the appearance and behavior of the alert, such as adding additional buttons or actions.
10. Sheet:
Example:
“`swift
.sheet(isPresented: $isSheetPresented) {
SomeView()
}
“`
Description: The `.sheet` modifier is used to present a modal sheet in your SwiftUI interface. It takes a boolean binding that controls whether the sheet is shown or hidden. Inside the closure, you can specify the content of the sheet, which can be any SwiftUI view. The sheet is typically dismissed by swiping it down or tapping a “Done” button.
Note: The examples provided are simplified and may require additional code to work correctly in a complete SwiftUI project.
