Swift Playground: NSXMLParser / parse() always returns false

Question

here's my code:

public class Payment: NSObject, NSXMLParserDelegate {

public var buchungsdatum:NSDate
public var valutadatum:NSDate
public var betrag:Double
public var verwendungszweck:String

public var creditorIban:String
public var creditorBic:String
public var creditorName:String

public var debitorIban:String
public var debitorBic:String
public var debitorName:String

override init() {
    buchungsdatum = NSDate()
    valutadatum = NSDate()
    betrag = 0.0
    verwendungszweck = ""

    creditorIban = ""
    creditorBic = ""
    creditorName = ""

    debitorBic = ""
    debitorIban = ""
    debitorName = ""
}

override public var description: String {
    return "Payment-Information:"
}

func beginParse() {
    let url = NSURL(fileURLWithPath: "/Users/Andi/Downloads/c53/CAMT/2015-10-06_C53_DE92300606010303502481_EUR_585142.xml")

    let xml = NSXMLParser(contentsOfURL: url)!

    xml.delegate = self
    xml.parse()

}

@objc public func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String]) {
    print("get an element")
}

@objc public func parserDidStartDocument(parser: NSXMLParser) {
    print("started")
}


@objc public func parserDidEndDocument(parser: NSXMLParser) {
    print("ended")
}

public func parser(parser: NSXMLParser, parseErrorOccurred parseError: NSError) {
    print("Fehler")
}
} 
var aPayment:Payment = Payment()
aPayment.beginParse()

Can anyone tell me why the parse() returns false and none of the delegate methods get called. Even the parseError one doesn't. I absolutely don't understand why.

Xcode even shows that the XML-File has content and that url isn't nil (see pic) Xcode shows the XMLContent in the playground

"and that makes me angry" Whoa, okay, I just stopped helping. — matt, Oct 16 '15 at 17:06
Ok, good. Second question, is it valid XML? Please post the actual file somewhere so we can examine. — matt, Oct 18 '15 at 09:01
Yep, it's very valid. It's a statement file from a bank. Sorry, can't post it (data security), but trust me, it's valid. It works when I hard code it as a string variable, but that's not want to do. — Andi Utzinger, Oct 18 '15 at 09:03
Next: Try running your code in a real app, not a playground. — matt, Oct 18 '15 at 09:13
Oh, one more idea. Load the NSData from the Url yourself and call init data instead of init contentsOfUrl. — matt, Oct 18 '15 at 09:15
Just tried to load the contents into a String via "contentsOfURL" and gives me the error 257 (no permission to view (the file?)). Wow... that was it? Thanks for the help anyways, very appreciated. — Andi Utzinger, Oct 18 '15 at 09:48
So I think in the playground there a some restrictions, right? Will try it in a real app project then. — Andi Utzinger, Oct 18 '15 at 09:51

It is most likely because your NSURL is nil.

Don't post comments as answers. – rmaddy Oct 16 '15 at 17:26
url is not nil, just look at the picture. – Andi Utzinger Oct 18 '15 at 08:34
