Develop a Mac Application

Need to have a small Mac app built in Swift. It is a REST client and will be for an inclusion into a larger app, but for now, I will need this part build stand alone. The app should be a simple window with a button to display a basic REST client. Click the button and the REST client should be showable via an action sheet. I've attached screen shots of what will be needed for the REST client displayable in the action sheet. 1. The basics The client should contain 2 parts - a top section and a bottom section. You can see this in screen shot 1. The top section has the basic url, http method, and submit button. The bottom section has tabs for configuring the http request. Screen shot 2 shows adding request params. These are key value and for a GET should be added to the URL on submit or as request body for the other http methods. I want to be able to add / delete rows for this via the + / - buttons on the right. Screen shot 3 is for request headers. Again, this is a basic key / value list with + / - buttons adding / deleting rows. Screen shot 4 is a small form to enter any http basic auth or digest auth credentials. Ignore the 'Preemptive Basic Auth' check box. Also ignore the 'Files' tab as that is not supported. 2. Submit Once the request has been set up and the Submit button is clicked, the client needs to fetch the data and then log out the text body via NSLog. I like using Stripe's api as a test because it's really clean and well documented. You can use whatever works best for you. Since this will be primarily used for making JSON requests to api's, I would suggest to limit testing to JSON - no xml or any other formats are necessary. The screenshots are taken from Cocoa Rest Client and feel free to use it as reference: [login to view URL] I need this to be a 100% Swift project, no Objective-C please and no 3rd partly library dependencies - this has to be a drop in to a bigger app and I don't want to manage any other 3rd party libraries. This also means that you will need to use the Apple HTTP api's for this (sorry, no AFNetworking / AlamoFire). I think this should be enough info to complete this project. I started a Swift version of this but abandoned it because I don't have the time to work on it. I did not back up the code so I can't provide a starting point - this will have to be done from scratch.
