Answer 1

Since you are using:

 TableViewController.requestFinished(broadcasts)

You should define the function as a class function:

class func requestFinished(requestedBroadcasts: [BroadcastModel]) {
    self.broadcasts = requestedBroadcasts  \* HERE IS THE ERROR *\
    self.tableView.reloadData()
}

Recommend you to figure out the difference between function and class function and difference between class itself and class instance

If you want to do something to a class instance, you must have the reference to it, instead of only having the class name.
