如何防止SwiftUI TextField的onChange之间的循环依赖？

Question

我正在开发一个 SwiftUI 视图，其中包含两个文本字段，一个用于金额，另一个用于百分比。两个 TextField 都使用 $ 符号绑定到各自的 @State 变量。

struct ContentView2: View {
    @State private var amount: String = ""
    @State private var percentage: String = ""
    
    var body: some View {
        VStack {
            TextField("enter value here", text: $amount)
            TextField("enter percentage here", text: $percentage)
            
                .onChange(of: amount, perform: onAmountChange(_:))
                .onChange(of: percentage, perform: onPercentageChange(_:))
        }
        .padding()
    }
    
    func onAmountChange(_ newValue: String) {
        // while setting percentage, `percentage` is a state property that triggers onAmountChange(_:)
        percentage = newValue
        // Is there a way to stop triggering the onPercentageChange(_:) method here?
    }
    
    func onPercentageChange(_ newValue: String) {
        // while setting amount, `percentage` is a state property that triggers onPercentageChange(_:)
        amount = newValue
        // Is there a way to stop triggering the onAmountChange(_:) method here?
    }
}
```
Issue:

The problem I'm facing is that when I update the amount, it triggers the onAmountChange(_:) method, which sets the percentage. However, setting the percentage also triggers the onPercentageChange(_:) method, creating a circular dependency

Question:

Is there a way to prevent this circular dependency and avoid the onAmountChange(_:) method from triggering when setting percentage, and vice versa? I want to update the values of amount and percentage without calling second function. Any guidance or alternative approaches would be highly appreciated! Thank you!
