'super.init' isn't called on all paths before returning from initializer

Question

I am new in swift and now i am stuck in inheritance . Here i am using two class class A, and class B . Class B is inheriting some properties of class A . Here is the code .

class A
{
    var objRunningJobs:UIViewController!
    var objCompletedJobs:UIViewController!
    init(objRunningJobs:UIViewController, objCompletedJobs: UIViewController) {
        self.objRunningJobs = objRunningJobs
        self.objCompletedJobs = objCompletedJobs
    }
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

}

class B: A
{
    override init(objRunningJobs:UIViewController, objCompletedJobs: UIViewController) {
        super.init(objRunningJobs: objRunningJobs, objCompletedJobs: objCompletedJobs)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

In class A , after init i am getting the error of 'super.init' isn't called on all paths before returning from initializer .

Short answer:

class A: UIViewController {
let objRunningJobs: UIViewController
let objCompletedJobs: UIViewController

init(objRunningJobs:UIViewController, objCompletedJobs: UIViewController) {
    self.objRunningJobs = objRunningJobs
    self.objCompletedJobs = objCompletedJobs
    super.init(nibName: "TestNib", bundle: nil)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

}

Replace 'TestNib' with yours. But it's a bad way to initialize UIViewController subclass. Probably, you don't understand role of UIViewController's and their hierarchy. What you want to do in your app?
