Text concatenation for localization purposes

I am trying to localize my app using this method: How to implement localization in Swift UI

In general it works. One problem I found is with text concatenation. Example: I have a translation for the text "bookings". To make it work I need to separate my previous code:

Text("bookings: 40")

to be:

Text("bookings")
    .fontWeight(.bold)
+ Text(": 40")
    .fontWeight(.bold)

Translation still works. The problem is that right now I need to have text formatting twice (in this example: fontWeight, but sometimes it's more complex).

I have tried to make it more simple like this:

Text("bookings" + ": 40)
    .fontWeight(.bold)

This code works in English, but is not being translated now to another languages. How should I change my code to make it work and keep it simple?

Text localization works with string interpolation, see for example the WWDC 2019: What's new in Swift session video, or Localization in SwiftUI, or this answer.

However, you have to use the correct format specifier. For strings, it is %@, for integers it is %lld. Example:

let value = 40

struct ContentView: View {
    var body: some View {
        Text("bookings: \(value)")
            .fontWeight(.bold)
    }
}

with the localization entry

"bookings: %lld" = "Buchungen: %lld";

in the Localizable.strings file results in the text "Buchungen: 40" to be displayed in a bold font:
