I am able to solve this question by following this link

What i did is as below :

@IBOutlet weak var viewTemp: UIView!
override var preferredFocusEnvironments : [UIFocusEnvironment] {
    //Condition
    return [viewTemp]
}

insted of this.

override weak var preferredFocusedView: UIView? {
    //Condition
    return viewTemp
}
