UIスクリーンショット

UICOLLectionView Cell Heightの変更

self.heightAnchor.constant = self.collectionViewHeight
self.collectionView.performBatchUpdates(nil)

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        let width = self.weekStackView.frame.width / 7
        let height = self.collectionViewHeight / 5
        return CGSize(width: width, height: height)
    }

UIView Animate

UIView.animate(withDuration: 0.5, delay: 0, options: [.curveLinear]) {
                self.heightAnchor.constant = self.collectionViewHeight
                self.heightAnchor.isActive = true
                self.calendarMemoViewHeightAnchor.constant = self.calendarMemoViewHeight
                self.calendarMemoViewHeightAnchor.isActive = true
                self.collectionView.performBatchUpdates(nil)
                self.calendarMemoView.layoutIfNeeded()
            }

次はね。
