how to parse parameter list in Swift?

[syrose01]

Hi,
We are writing a query that can parse all symbols in our Swift code.
But we discovered something strange while working.

If Swift code like the following,

func greet(firstName: String, lastName: String, age: Int) {
    print("Hello, \(firstName) \(lastName)! You are \(age) years old.")
}

and the query statement is as follows,

(function_declaration
  (simple_identifier) @func_name
  (parameter) @param_list)

the result of the query is:

We want to parse parameter list, but only parameters appear.
In other words, what we want is as follows.

Bag.swift
  pattern: 0
    capture: 0 - func_name, start: (0, 5), end: (0, 10), text: `greet`
    capture: 1 - param_list, start: (0, 11), end: (0, 28), text: `firstName: String, lastName: String, age: Int`

So we checked other Swift codes and found that they all had no parameter list.
Can you tell me if this part is not implemented or if we are doing something wrong?
I wonder if you can tell me the correct query statement if I'm doing something wrong.

I'll wait for your reply.
Sincerely,
