## Sharing SwiftUI state with @Observable
```swift
import SwiftUI
@Observable
class User {
var name = "Kevin"
var lastName = "Cuadros"
}
struct SecondView: View {
@Environment(\.dismiss) var dismiss
let name: String
var body: some View {
Text("Hello, \(name)!")
Button("Dismiss"){
dismiss()
}
}
}
struct ContentView: View {
@State private var user = User()
@State private var showingSheet = false
var body: some View {
VStack {
Text("Your name is \(user.name) \(user.lastName)")
TextField("First name", text: $user.name)
TextField("Last name", text: $user.lastName)
Button("Show Sheet") {
showingSheet.toggle()
}
.sheet(isPresented: $showingSheet) {
SecondView(name: user.name)
}
}
.padding()
}
}
#Preview {
ContentView()
}
```
## Deleting items using onDelete()
```swift
import SwiftUI
struct ContentView: View {
@State private var numbers = [Int]()
@State private var currentNumber = 1
var body: some View {
NavigationStack {
VStack {
List {
ForEach(numbers, id: \.self) {
Text("Row \($0)")
}
.onDelete(perform: removeRows)
}
Button("Add number") {
numbers.append(currentNumber)
currentNumber += 1
}
}
.toolbar {
EditButton()
}
}
}
func removeRows(at offsets: IndexSet){
numbers.remove(atOffsets: offsets)
}
}
#Preview {
ContentView()
}
```
## AppStorage encode
```swift
import SwiftUI
struct User: Codable {
let firstName: String
let lastName : String
}
struct ContentView: View {
@AppStorage("tapCount") private var tapCount = 0
@State private var user = User(firstName: "Taylor", lastName: "Swift")
var body: some View {
VStack {
Button("Tap Count: \(tapCount)") {
tapCount += 1
let encoder = JSONEncoder()
if let data = try? encoder.encode(user) {
UserDefaults.standard.set(data, forKey: "UserData")
}
}
}
}
}
#Preview {
ContentView()
}
```
