Swift 使滑块值仅可单向调节

是否有可能使SwiftUI滑块只向一个方向移动？例如：仅向右侧增加值

import SwiftUI
struct ContentView: View {
    @State private var sliderValue = 0.0
    var body: some View {
        VStack {
            Text(sliderValue.description)
            Slider(value: $sliderValue)
        }
    }
}
struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

在我的应用程序中，sliderValue只能调整为增加，不能减少是的，你可以，但你应该使用自定义绑定

import SwiftUI

struct ContentView: View {
    
    @State private var sliderValue = 0.0
    
    var body: some View {
        
        VStack {
            
            Text(sliderValue.description)
            
            Slider(value: Binding.init(get: { () -> Double in return sliderValue },
                                       set: { (newValue) in if (newValue > sliderValue) { sliderValue = newValue } }))
            
        }
        
    }
}
