Swift 九九乘法App/Multiplication Table App

The following is a Multiplication Table App that I created with Swift in Xcode.

The following is my codes of the App interface.

I added the Title “Multiplication Table”at the top and an image and at the bottom of the interface separately other than the codes.

import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let width = view.frame.width / 10
var x: CGFloat = 0
for i in 0…9{
print(x)
var y: CGFloat = width
let label = UILabel(frame: CGRect(x: x, y: y, width: width, height: width))
if i == 0 {
label.text = “X”
} else {
label.text = “\(i)”
}
view.addSubview(label)
x = x + width
}
x = 0
for i in 0…9{
print(x)
var y: CGFloat = width * 2
let label = UILabel(frame: CGRect(x: x, y: y, width: width, height: width))
if i == 0 {
label.text = “1”
} else {
label.text = “\(i)”
}
view.addSubview(label)
x = x + width
}
x = 0
for i in 0…9{
print(x)
var y: CGFloat = width * 3
let label = UILabel(frame: CGRect(x: x, y: y, width: width, height: width))

label.text = “2”
} else {
label.text = “\(2 * i)”
}
view.addSubview(label)
