I'm lost, why Text("\(type)") would get compile error meantime Text(str) is not. Did that string interpolation not create a string?

For the error please check screenshot in below.

enum ExpenseType: Codable, CaseIterable {
    case Personal
    case Bussiness
}

struct AddView: View {
    @State private var type: ExpenseType = .Personal
    let types: [ExpenseType] = ExpenseType.allCases

    var body: some View {
        Form {
                ...
                
                Picker("Type", selection: $type) {
                    ForEach(types, id: \.self) { type in
                        let str = "\(type)"
                        Text(str)
                        // Compile error
                        Text("\(type)")
                    }
                }
                ...
            }

CodePudding user response：

Xcode fails to detect which Text initializer should be used, a rather annoying bug.

Possible workarounds:

1. Using String(describing:) initializer:

Text(String(describing: type))

2. Declaring a variable at first:

let text = "\(type)"
Text(text)

You need to use rawValue, and try to loop more efficiently over the allCases.

enum ExpenseType: String, CaseIterable {
    case Personal
    case Bussiness
}

struct ContentView: View {
    @State var expenseType = ExpenseType.Personal
    var body: some View {
        List {
            Picker(selection: $expenseType, label: Text("Picker")) {
                ForEach(ExpenseType.allCases, id: \.self) { type in
                    Text(type.rawValue)
                }
            }
            .pickerStyle(.inline)
        }
    }
}
