Subview's size not equal to its superview

Problem:

The yellow part is the subview( The subview is UIImageView, and the superview is UIView. ), its size is suppose to be the same as its superview (the gray part), what should I do to fix this?

Screen Images:

Here's the code: 

var linkedMemory = Memory(masteryLevel: 1, algorithm: Algorithm.algorithm1.chooseAlgorithm(), forgetRatio: 0, lastStudyTime: Date(), front: #imageLiteral(resourceName: "Ideas-Yellow"), back: #imageLiteral(resourceName: "Ideas-Blue"))

var frontView: UIView {
    let front = showContent(of: linkedMemory.front)
    return front
}

convenience init(memory: Memory) {
    self.init(frame: CGRect())
    self.linkedMemory = memory
    self.setupView()
}

override init(frame: CGRect) {
    super.init(frame: frame)
}

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

func setupView() {
    self.layer.cornerRadius = 20
    self.layer.shadowRadius = 12
    self.layer.shadowOpacity = 0.15
    self.layer.masksToBounds = true
    addGesture()
    sizeNAddSubview(view: frontView)
}

func sizeNAddSubview(view: UIView) {
    view.frame.size = self.bounds.size
    addSubview(view)
}

func showContent(of linkenMemory: Any) -> UIView {
    var contentView = UIView()
    if let content = linkenMemory as? UIImage {
        let imageView = UIImageView()
        imageView.image = content
        contentView = imageView
    }
    if let content = linkedMemory as? String {
        let label = UILabel()
        label.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
        label.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
        let text = content
        label.text = text
        contentView = label
    }
    return contentView
}

Here are the constraints:

You can either give constraints as equal height and equal width of superview [or] If you are setting this view before layout pass, the size of superview will not be the actual size, so you've to move the code to either viewDidAppear() or viewDidLayoutSubviews()
