Inside your view controller override viewDidLayoutSubviews method

@IBOutlet weak var collectionView: UICollectionView!

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if let layout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout {
        let itemWidth = view.bounds.width / 3.0
        let itemHeight = layout.itemSize.height
        layout.itemSize = CGSize(width: itemWidth, height: itemHeight)
        layout.invalidateLayout()
    }
}

(collectionView property is your collectionView)
