Kitura Extra argument 'query' in call

## Context and Description
I'm a student developping an iOS application with Kitura https://github.com/charelF/Radar
I am getting a strange error which seems to be a bug from Kitura, at least I can not possibly understand what I am doing wrong. I implemented the client.get method and it throws an error when I include the `query` parameter.

### Environment Details
I am using Xcode 11.1, macOS catalina, swift 5.1

### Steps to Reproduce
Nothing particular, as you can see Xcode detects the line as not being correct even though it should be correct.

_I initially posted this issue on the Kitura Repo, but it seems to fit better here_
