tableView data source empty in viewDidLoad() - Swift

Question

Below is my ViewController code. The println in GetRequest prints the correct data that it receives from the HTTP GET request. At this point, tableData has 10 key-value pair

Answer 1

Rearrange the orders of the method calls:

override func viewDidLoad() {
    super.viewDidLoad()
    self.tableView.delegate = self
    self.tableView.dataSource = self
    var apiInfo = GetWaitTimes()
    GetRequest(apiInfo.BorderCrossingApi+"?AccessCode="+apiInfo.AccessCode)
    tableView.reloadData()
}

Explanation: you set the delegate and dataSource before you GetRequest() so the dataSource won't be nil.
