XYScrollViewSample, Vertical and Horizontal scroll view, Swift 4

In case of making scroll view like showing calendar, need to implements vertical and horizontal scroll functionality. Here is a sample code of showing calendar. Hope this will help you.

Project code is Github.

Part of CollectionView

extension ViewController: UICollectionViewDataSource, UICollectionViewDelegate {

    func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1
    }
	
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
		return	self.numberOfDays[collectionView.tag]
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell{
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath)
		let dayLabel = cell.contentView.viewWithTag(1) as! UILabel
		let weekLabel = cell.contentView.viewWithTag(2) as! UILabel

		let formatter = self.getFormatter()
		let year = formatter.string(for: Date())!
		formatter.dateFormat = "YYYY/MM/dd"
		let targetDay = String(format: "%@/%02d/%02d", year, collectionView.tag + 1, indexPath.row + 1)
		let target = formatter.date(from: targetDay)
		var calendar = Calendar(identifier: .gregorian)
		calendar.timeZone = TimeZone(identifier: "Asia/Tokyo")!
		let weekday = calendar.component(.weekday,from: target!)

		dayLabel.text = "\(indexPath.row + 1)"
		weekLabel.text = self.weekLabel[weekday - 1]
		
		if weekday == 1 {
			dayLabel.backgroundColor = UIColor.red
			dayLabel.textColor = UIColor.white
			dayLabel.layer.borderColor = UIColor.white.cgColor
			weekLabel.textColor = UIColor.red
		} else {
			dayLabel.backgroundColor = UIColor.white
			dayLabel.textColor = UIColor.black
			dayLabel.layer.borderColor = UIColor.black.cgColor
			weekLabel.textColor = UIColor.black
		}

		return cell
    }

	func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
		let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath)
		let dayLabel = cell.contentView.viewWithTag(1) as! UILabel
		print(dayLabel.text!)
	}
}

Part of UITableView

extension ViewController: UITableViewDelegate, UITableViewDataSource {

	func numberOfSections(in tableView: UITableView) -> Int {
		return	1
	}

	func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
		return	12
	}

	func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
		let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! CalendarTableViewCell
		cell.monthLabel.text = "\(indexPath.row + 1)"
		cell.daysCollectionView.delegate = self
		cell.daysCollectionView.tag = indexPath.row
		return cell
	}

	func tableView(_ tableView: UITableView,didSelectRowAt indexPath: IndexPath) {
		self.tableView.deselectRow(at: indexPath, animated: true)
	}
}
