Add space between cells in Swift 3 - ios

Question

I want to add space between the cells that I have in my UITableView.
Here's my code. What I mean is cell then space then cell then space etc.
class TableViewController: UITableViewController {
var textArray = [String]()
var cellsArray = ["1","2","3"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
textArray = ["","",""]
self.tableView.estimatedSectionHeaderHeight = 80
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return textArray.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: (cellsArray[indexPath.row]), for: indexPath) as UITableViewCell
return cell
}
}

Answer 1

Use this for space between two cells
let testView: UIView = UIView(frame: CGRect(x:0, y:0, width:TableView1.frame.size.width , height:(cell?.contentView.frame.size.height)! - 5 ))
testView.backgroundColor = UIColor.blue
testView.alpha = 0.5
testView.isUserInteractionEnabled = true
testView.layer.cornerRadius = 5
testView.layer.masksToBounds = true
cell?.contentView.addSubview(testView)
cell?.contentView.sendSubview(toBack: testView)

Just simple approach if you like it ...
let tableViewCellIdentifier = "TableViewCell"
class ViewController: UITableViewController {
var cellsArray = ["1","2","3","4","5","6"]
override func viewDidLoad() {
super.viewDidLoad()
tableView.separatorColor = UIColor.clear
tableView.register(UINib(nibName: tableViewCellIdentifier, bundle: nil), forCellReuseIdentifier: tableViewCellIdentifier)
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cellsArray.count
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 80
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: tableViewCellIdentifier) as! TableViewCell
cell.customCellLabel.text = cellsArray[indexPath.row]
return cell
}
}
Custom cell
class TableViewCell: UITableViewCell {
#IBOutlet weak var customCellLabel: UILabel!
#IBOutlet weak var innerView: UIView!
}

If you have a vertical scroll for your UITableViewController or UICollectionViewController you need to add this code:
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
return 10
}
