SwiftUI Localization

Question

I am facing localisation issue in SwiftUI. Issue is happening when translation has placeholder. I am getting error "Instance method 'appendInterpolation' requires that 'LocalizedStringKey' conform to '_FormatSpecifiable'"

Code

struct Translation {
    struct school{
        static var location: LocalizedStringKey {
            return "schoolLocation %@"
        }
     }
}

Translation file

"schoolLocation %@" = "My school location is %@";

SwiftUI view

var location = "Some Name"
.navigationBarTitle("\(Translation.school.location) \(location)")

Please help me if i am doing something wrong.

Does this answer your question? [How to implement localization in Swift UI](https://stackoverflow.com/questions/58578341/how-to-implement-localization-in-swift-ui) — LuLuGaGa, Aug 01 '20 at 17:56
No, I have placeholder for dynamic value and for key i am maintaining in structure of LocalizedStringKey. My code is working perfectly for static localization values. but i am getting compilation error for dynamic value. — Rocker, Aug 01 '20 at 18:02
@Rocker have you tried removing `%@` from the key as it's not necessary? you can have "schoolLocation" = "My school location is %@"; in your translation file. — Mohammad Rahchamani, Aug 01 '20 at 20:11
Still have getting compilation error "Instance method 'appendInterpolation' requires that 'LocalizedStringKey' conform to '_FormatSpecifiable'" on line .navigationBarTitle("\(Translation.school.location) \(location)") — Rocker, Aug 02 '20 at 05:30

What you are doing is you are giving back an already interpolated string with %@ to an interpolated string. So the string that you are generating looks like this: "schoolLocation %@ Some Name". You can do it this way:

struct Translation {
    struct school{
        static func location(name: String): LocalizedStringKey {
            return "schoolLocation \(name)"
        }
     }
}

And then you can use your translation like this:

var location = "Some Name"
.navigationBarTitle(Translation.school.location(name: location))

Is there way we can assign localized value to String? There i am getting error — Rocker, Sep 07 '20 at 07:58
