Can you refactor function parameter's name in Xcode?

Question

I just upgraded to Xcode 10 and and noticed that I cannot refactor the parameter's name in a function. I haven't been using Xcode 9 for long time. So I am not sure if this was possible in Xcode 9 and Xcode 10 lost it.

Thanks

How to rename a Swift init parameter

I would expect to rename an init parameter where it is declared. Xcode doesn't allow this.

With some experiments, I stumbled upon an unexpected place where init parameters can be renamed: Wherever they are used, you can control click on an init parameter and rename it using the context menu.

class Rename {
    // Do NOT control click on parameter here:
    init(parameterToBeRenamed: String) {
    }
}
class Use {
    func test() {
        // to rename parameterToBeRenamed, control click on parameter here:
        let _ = Rename(parameterToBeRenamed: "Hello World")
    }
}
