在SwiftUI中重置绑定变量

@State private var count = 0

// 重置绑定变量
count = 0

struct User {
    var name: String
    var age: Int
    
    mutating func reset() {
        name = ""
        age = 0
    }
}

@State private var user = User(name: "John", age: 30)

// 重置绑定变量
user.reset()

struct ContentView: View {
    @State private var count = 0
    
    var body: some View {
        VStack {
            Text("Count: \(count)")
            
            Button("Reset") {
                count = 0 // 重置绑定变量
            }
        }
    }
}
