You need to authenticate with the server using App Only Authentication rather than passing in an OAuth Token.

As well as this, you are also not requesting status' with userId correctly as you are passing in the user's screen name. You need to obtain the user id with the username and then request for status'.

The complete working code is below:

required init(coder aDecoder: NSCoder) {
    self.swifter = Swifter(consumerKey: "cKEY", consumerSecret: "cSECRET", appOnly: true)
    super.init(coder: aDecoder)

    self.swifter.authorizeAppOnlyWithSuccess({ (accessToken, response) -> Void in
        self.twitterIsAuthenticated = true
    }, failure: { (error) -> Void in
        println("Error Authenticating: \(error.localizedDescription)")
    })
}

@IBAction func getUserButtonPressed(sender: UIButton?) {
    if (self.twitterIsAuthenticated) {
        self.getTwitterUserWithName("erhsannounce")
    } else {
        // Authenticate twitter again.
    }
}

func getTwitterUserWithName(userName: String) {
    self.swifter.getUsersShowWithScreenName(userName, includeEntities: true, success: { (user) -> Void in
        if let userDict = user {
            if let userId = userDict["id_str"] {
                self.getTwitterStatusWithUserId(userId.string!)
            }
        }
        }, failure: failureHandler)
}

func getTwitterStatusWithUserId(idString: String) {
    let failureHandler: ((error: NSError) -> Void) = {
        error in
        println("Error: \(error.localizedDescription)")
    }

    self.swifter.getStatusesUserTimelineWithUserID(idString, count: 20, sinceID: nil, maxID: nil, trimUser: true, contributorDetails: false, includeEntities: true, success: {
        (statuses: [JSONValue]?) in

        if statuses != nil {
            self.tweets = statuses
        }

        }, failure: failureHandler)
}

It looks as though you are not Authenticating with the server.

From your code I can see you are using OAuth authentication initialisation but are failing to call the authenticate function.

swifter.authorizeWithCallbackURL(callbackURL, success: {
    (accessToken: SwifterCredential.OAuthAccessToken?, response: NSURLResponse) in

    // Handle success

    },
    failure: {
        (error: NSError) in

        // Handle Failure

    })

Add this in and then call your getTwitterTimeline() afterwards.

I hope this helps
