If / Else won't run - if-statement

Question

I am working with the IF/Else training in Udemy and cannot see where my error/issue is.
When I run the code, nothing happens and it doesn't activate an error(in XCode)
When I apply it to the (online)playground, it's identifying almost everything as an error.
I'm a beginner. I'm follwong the lessons but if she doesn't supply the solution, I can't see where I went wrong. Help.
import UIKit
class ViewController: UIViewController {
let softTime = 5
let mediumTime = 7
let hardTime = 12
#IBAction func hardnessSelected(_ sender: UIButton) {
let hardness = sender.currentTitle
}
func hardness(temp: Int){
let hardness = Int.random(in: 0 ... 12)
if hardness >= 10 {
print("Hard Boiled")
};if hardness <= 9 {
print("Medium Boiled")
} else {
print("Soft Boiled")
}
}
}

Answer 1

You have an unnecessary semi-colon (';') on your second if, also you should use else if when you have another condition you want to check for. Try this code:
import UIKit
class ViewController: UIViewController {
let softTime = 5
let mediumTime = 7
let hardTime = 12
#IBAction func hardnessSelected(_ sender: UIButton) {
let hardness = sender.currentTitle
}
func hardness(temp: Int){
let hardness = Int.random(in: 0 ... 12)
if hardness >= 10 {
print("Hard Boiled")
} else if hardness <= 9 {
print("Medium Boiled")
} else {
print("Soft Boiled")
}
}
}
