Uicollection view dynamic height but fixed width

问题

I am working with UICollectionView I have 4 different kind of cells. Every cell is designed in xib file . when i load them in collection view it goes out of screen. i don't know why it is happening. Some cells have fixed height while some have dynamic height (depends on data coming from API). So is there any possible way to solve this issue. i have tried Estimate size automatic to dynamic

override func awakeFromNib() {
    super.awakeFromNib()
    self.contentView.translatesAutoresizingMaskIntoConstraints = false
    let screenwidth = UIScreen.main.bounds.size.width
    widthAnchor.constraint(equalToConstant: screenwidth-20)
}

func setSize () {
    let layout = mainCollection.collectionViewLayout as! UICollectionViewFlowLayout
    layout.sectionInset = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)}

}
