requires that 'moveView' conform to 'StringProtocol' in swiftui-CodePudding

i had make a struct to pass the ObservedObject value change.

struct moveView : View {

    @Binding var move : Bool

    var body: some View {
        if move{
           return Text("1")
        }else{
           return Text("2")
        }
    }
}
struct TextView : View {

    @ObservedObject var skc:xiangcene

    var body: some View {
        Text("test")
         .opacity(moveView(move: $skc.move) == "1" ? 0.1 : 0.8)    // it show
Referencing operator function '==' on 'StringProtocol' requires that 'moveView' conform to 'StringProtocol'
    }
}

the compiler complaint “Referencing operator function '==' on 'StringProtocol' requires that 'moveView' conform to 'StringProtocol'” how can i fix that？

CodePudding user response：

Your struct is of type 'View' and you are comparing it to a 'String' constant.

You could check the boolean value:

.opacity(moveView(move: $skc.move).move ? 0.1 : 0.8)

But using a the expression:

moveView(move: $skc.move)

does not make sense here. You are creating a new view here with the value of the variable.

Better:

.opacity( skc.move ? 0.1 : 0.8)
