Can I pass a string containing markdown to custom view?-CodePudding

I want to pass a string containing markdown to a custom view and have the formatting done in that view.

Example:

struct MyTest: View {
    let text: String // Some other type needed here
    
    init(_ text: String) { self.text = text }
    
    var body: some View {
        Text(text)
        Text("*Inline*")
    }
}

Use the view, eg.: MyTest("*Test*")

This will produce the output:

*Test* Inline

The goal is to get the output:

Test Inline

Is it possible to have the formatting passed to the Text(text) line in the custom view?

CodePudding user response：

The formatting markdown "magic" comes from this initialiser of Text, which takes a LocalizedStringKey. Since LocalizedStringKey conforms to ExpressibleByStringLiteral, Text("*Inline*") will call this initialiser, but Text(someStringVariable) will not.

So to format the markdown in the text property, you just need to call that initialiser. You can either make text a LocalizedStringKey itself:

struct MyTest: View {
    let text: LocalizedStringKey
    
    init(_ text: LocalizedStringKey) { self.text = text }
    
    var body: some View {
        Text(text)
        Text("*Inline*")
    }
}

Or create a LocalizedStringKey when creating the Text:

Text(LocalizedStringKey(text))

By using this initialiser of Text, you get the added benefit of localising the text! :D
