Pass date in URL for PHP request using Swift

I have a swift project that connects to a PHP service which returns data in JSON format. One of the requests requires two timestamps be passed in the URL. The app calculates inventory availability for a given date range, so these are user-generated dates and times in the following format:

"1/15/2015 16:00"

When testing the PHP file in a browser and manually injecting the parameters, the desired URL is as follows:

http://localhost/php/FM_ScriptReturnTest.php?barcode=2010&start=10/1/2014 8:00 AM&end=10/5/2014 4:00 PM

The results are returned correctly. However, when generating a URL in Swift containing these time/date variables using println(url: (url)) returns:

url: nil

And of course, the solution doesn't work if the URL has no value. I suspect is has something to do with the slashes in the date, is there any way around this?

Solved:

'''swift

class func scanItemOutInfo (barcode:String) -> NSDictionary {

    //direct to php file location
    let server:String = GlobalVars.serverAddress
    let companyId:String = GlobalVars.currentCompanyId
    let start:String = GlobalVars.currentJobStart as String!
    let end:String = GlobalVars.currentJobEnd as String!


    let startEncoded = start.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!
    let endEncoded = end.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!

    let phpFile:String = "/php/FM_ScriptReturnTest.php"


    let baseURL = NSURL(string: "http://\(server)\(phpFile)")
    let url = NSURL(string: "?barcode=\(barcode)&start=\(startEncoded)&end=\(endEncoded)", relativeToURL: baseURL)
    let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
    var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 20.0)
    request.HTTPMethod = "POST"

    //set Content-Type in HTTP header
    //let boundaryConstant = "----------V2ymHFg03esomerandomstuffhbqgZCaKO6jy";
    //let contentType = "multipart/form-data; boundary=" + boundaryConstant
    //NSURLProtocol.setProperty(contentType, forKey: "Content-Type", inRequest: request)

    // set data
    var dataString = ""
    let requestBodyData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
    request.HTTPBody = requestBodyData

    // set content length
    //NSURLProtocol.setProperty(requestBodyData.length, forKey: "Content-Length", inRequest: request)

    var response: NSURLResponse? = nil
    var error: NSError? = nil
    let reply: NSData! = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&error)

    let results = NSString(data:reply!, encoding:NSUTF8StringEncoding)


    //Parse JSON results

    var jsonerror:NSError?

    let swiftObject:AnyObject = NSJSONSerialization.JSONObjectWithData(reply, options:  NSJSONReadingOptions.AllowFragments, error:&jsonerror)!

    let nsArrayObject:NSDictionary = swiftObject as NSDictionary
    let itemDict:Dictionary = nsArrayObject as Dictionary



    println("Dictionary: \(itemDict)")

    return itemDict
}
