Description
public extension Label where Title == Text, Icon == Image {
nonisolated static func someLabel() -> Self {
return Label("Something", systemImage: "heart.filled")
}
}
struct ContentView: View {
var body: some View {
Label.someLabel()
}
}
Leads to a compilation error in Kotlin:
fun Label.Companion.someLabel(): Label<Text, Image> = Label(LocalizedStringKey(stringLiteral = "Something"), systemImage = "heart.filled")
// No type arguments expected for class 'Label'.
Apparently the generated Label<Text, Image> is incorrect code-gen for Kotlin?

Research direction
Start with the Swift extension and the generated Kotlin declaration shown in the issue, then inspect the SKIP translation path for generic Swift view types. The work is done when this example transpiles to Kotlin without invalid type arguments and the resulting Kotlin compiles.
