Writing your own api client

I had to make paramString += "\(escapedKey)=\(escapedValue)&"

to unwrap like paramString += "\(escapedKey!)=\(escapedValue!)&"

to get this to work

Thanks @rajohns08, looks like stringByAddingPercentEncodingWithAllowedCharacters calls generate optionals there. I'll wrap them in an if let block.

Additionally, I had to change the value variable to a String before adding the encoding:

let escapedValue = String(value).stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet())

instead of

let escapedValue = value.stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet())

otherwise I get a NSException.
