If you don't want to change the php code, in Swift you should send url-encode format message, li:

// UPDATED with corrections from @Rob

    var params = ["param1":"value1", "papam2": "value 2"]
    var body = ""
    for (key, value) in params {
        body = body.stringByAppendingString(key)
        body = body.stringByAppendingString("=")
        body = body.stringByAppendingString(value.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)
        body = body.stringByAppendingString("&")
    }
    body = body.substringToIndex(advance(body.startIndex, countElements(body)-1)) // remove the last "&"
    request.HTTPBody = body.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
