NSURLQueryItem

[dpfannenstiel]

I saw that in write-your-own-api-clients-swift.md you're establishing parameters by using percent escapes. Consider modifying it to include NSURLQueryItem. It can reduce the cargo cult programming that a lot of developers (myself included) encounter when trying to format a URL.

Thanks for the suggestion @dpfannenstiel! I agree, NSURLQueryItem is probably the proper way to go about things. I'll look into adding it into the post - though it's really just a template for the client itself, the format for the request body will vary from provider to provider.

If you want to submit a PR with how you'd do it, I'd happily include it with attribution.
