SwiftUI Text doesn't localise when inside ForEach-CodePudding

When my Text gets it's string from an array, it doesn't localise, but when I hard-code it in, it does:

Localizable.strings

"greeting1" = "Hello there";
"greeting2" = "Howdy";

(Localised into English)

My View

var localisedStrings = ["greeting1", "greeting2"]

struct Message: View {
    var body: some View {
        ForEach(localisedStrings, id: \.self) { string in
            Text(string)
        }
    }
}

The text will just write the key, like "greeting1", rather than "Hello there"

Is there a way to force the Text object to use a localised string? Or is it changing somehow because it's getting it's content from a ForEach loop?

My View (hard coded)

//var localisedStrings = ["greeting1", "greeting2"]

struct Message: View {
    var body: some View {
        //ForEach(localisedStrings, id: \.self) { string in
            Text("greeting1")
        //}
    }
}

This works just fine, and results in the text displaying "Hello there".

CodePudding user response：

It works when you hardcode the string in, because you are using this initialiser, which takes a LocalizedStringKey.

LocalizedStringKey is ExpressibleByStringLiteral, but the word string in Text(string) is not a "string literal", so it calls this initialiser instead, and is not localised. You can initialise an instance of LocalizedStringKey directly, in order to localise it:

Text(LocalizedStringKey(string))

CodePudding user response：

It's because here you are using plain String Swift type

var localisedStrings = ["greeting1", "greeting2"]

and here you are using SwiftUI own LocalizedStringKey type

Text("greeting1")

To fix your issue map your string to LocalizedStringKey

struct Message: View {
    var body: some View {
        ForEach(localisedStrings, id: \.self) { string in
            Text(LocalizedStringKey(string))
        }
    }
}

Text.init(_:tableName:bundle:comment:)
