Hello, in commonMain I’ve the following expect:

Copy code

@Composable
expect fun PlatformFont(name: String, weight: FontWeight, style: FontStyle): Font

Then in androidMain:

Copy code

@Composable
actual fun PlatformFont(name: String, weight: FontWeight, style: FontStyle): Font {
    return with(LocalContext.current) {
        Font(resources.getIdentifier(name, "font", packageName), weight, style)
    }
}

jvm:

Copy code

@Composable
actual fun PlatformFont(name: String, weight: FontWeight, style: FontStyle): Font =
    androidx.compose.ui.text.platform.Font("font/${name}.ttf", weight, style)

Can anyone help me with iosMain actual? 🙏 Thanks!

You can use https://github.com/chrisbanes/tivi/blob/main/common/ui/resources/fonts/src/iosMain/kotlin/app/tivi/common/ui/resources/Fonts.ios.kt from @cb project.

I had to make

framework.isStatic = true

to solve it

Now, I’m having a runtime error:

Uncaught Kotlin exception: kotlin.IllegalStateException: File <name>.ttf not found in Bundle

I’ll double check the tivi sample to see what have I missed

Copy code

struct Fonts {
  static let Led = "LedPanelStationOn" //turns out that using printFontNames() insinde .onAppear() reveals the real name...
   
  static func printFontNames() {
    for family: String in UIFont.familyNames {
      print(family)
      for names: String in UIFont.fontNames(forFamilyName: family) {
        print("== \(names)")
      }
    }
  }
}

I was using Led.tff but for iOS “Led” does not exists. So with this code I found out the “real name” Changed the files and it works 🙂
