Initializer `init(:_rowContent:)` requires that `Type` confirm to `Identifiable`

I am following the KMM tutorial and was able to successfully run the app on Android side. Now I would like to test the iOS part. Everything seems to be fine except the compilation error below. I suppose this must be something trivial, but as I have zero experience with iOS/Swift, I am struggling fixing it.

My first attempt was to make RocketLaunchRow extend Identifiable, but then I run into other issues... Would appreciate any help.

xcode version: 12.1

                Text(launchText).foregroundColor(launchColor)
                Text("Launch year: \(String(rocketLaunch.launchYear))")
