ios Swift fatal error: use of unimplemented initializer 'init()'

“Unlike subclasses in Objective-C, Swift subclasses do not inherit their superclass initializers by default.”

Automatic Initializer Inheritance

• Rule 1: If your subclass doesn’t define any designated initializers, it automatically inherits all of its superclass designated initializers.
• Rule 2: If your subclass provides an implementation of all of its superclass designated initializers—either by inheriting them as per rule 1, or by providing a custom implementation as part of its definition—then it automatically inherits all of the superclass convenience initializers.

Since you have override the init(coder aDecoder: NSCoder), TimeLineTableViewController won't have the init() initiailzer.

You can provide an implementation of all of its superclass designated initialisers like this

override init() {
        super.init()
}

override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}

required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
}

, or just delete the implementation of init(coder aDecoder: NSCoder).
