无法推断复杂的闭包返回类型；添加显式类型以消除自定义TextField的歧义

Question

我正在尝试接收文本字段文本并将其发送到另一个结构。但是得到这个错误。 同样，当我尝试调用.onRecieve（Just（text）}数据时，... Xcode无法理解什么是正义。

struct CardInfo : View {
@State var creditCard : CreditCard
@State var isSaved: Bool = false
@State private(set) var text = ""
var body: some View {
    VStack {
        CustomTextField(data: $text, tFtext: "Kartin Uzerindeki Isim", tFImage: "user")
            .textContentType(.givenName)
            .onReceive(text) { data in
                creditCard.cardOwnerName = text
        }
        CustomTextField(data: $text, tFtext: "Kredi Kart Numarasi", tFImage: "credit")
            .textContentType(.oneTimeCode)
            .keyboardType(.numberPad)
        HStack {
            CreditCardDateTextField(tFtext: "", tFImage: "date")
                .textContentType(.creditCardNumber)
            Spacer()
            Text("")
                .overlay(
                    Rectangle()
                        .frame(width: 70, height: 53))
            Text("|")
                .foregroundColor(.black)
            CustomTextField(data: $text, tFtext: "CCV", tFImage: "")
                .textContentType(.creditCardNumber)
        }
        .foregroundColor(Color(#colorLiteral(red: 0.9647058824, green: 0.9725490196, blue: 0.9882352941, alpha: 1)))
        Group {
            CustomTextField(data: $text, tFtext: "Kart Ismi", tFImage: "cardEdit")
            Spacer()
            Button(action: {
                self.isSaved.toggle()
            }, label: { CustomButton(title: "Kaydet", icon: .none, status: .enable)
            })
        }
    }
    .edgesIgnoringSafeArea(.all)
    .padding()
}

}

您不能在状态上使用.onReceive，需要使用Just框架中定义的发布者，例如Combine，因此需要导入它。

import Combine

...

        CustomTextField(data: $text, tFtext: "Kartin Uzerindeki Isim", tFImage: "user")
            .textContentType(.givenName)
            .onReceive(Just(text)) { data in
                creditCard.cardOwnerName = text
        }
