  //Write your code inside this function.
  switch day {
    case 1:

    case 3:
    print("Wednesday")

Why do we need the statement : let aNumber = Int(readLine()!)! in every code? because whenever I apply it on my playground. It does not work and always show this.

When I take it out of my code, it works properly (as below). Can anyone please explain that to me? Many thanks!!

Hope it will help you 👍

So basically I just did a reset on the challenge page and then just tried again.

Only use this.

switch day {
case 1:
print("Monday")
case 2:
print("Tuesday")
case 3:
print("Wednesday")
case 4:
print("Thursday")
case 5:
print("Friday")
case 6:
print("Saturday")
case 7:
print("Sunday")
default:
print("Error")

oh my....as usual it would give me errors again, while working in my playground....so came here to check...you all have the same, I mean this one is quite easy....in the end I didn't copy and paste the last }...(smacks own head)

This worked for me
{ switch day { case 1: print ("Monday")
case 2: print ("Tuesday")
case 3: print ("Wednesday")
case 4: print ("Thursday")
case 5: print ("Friday")
case 6: print ("Saturday")
case 7: print ("Sunday")
default: print ("Error")
}
}

////Don't change this
var aNumber = Int(5)

func dayOfTheWeek(day: Int) {
switch day {
case 1:print("Monday")
case 2:print("Tuesday")
case 3:print("Wednesday")
case 4:print("Thursday")
case 5:print("Friday")
case 6:print("Saturday ")
case 7:print("Sunday ")
default:print("Error")
}
}
//Try out some different numbers here
//Don't copy the line below into Udemy

dayOfTheWeek(day: 5)

////Don't change this

func dayOfTheWeek(day: Int) {
let day = Int.random(in: 1...7)
switch day {
case 1:
print("monday")
case 2:
print("tuseday")
case 3:
print("wansday")
case 4:
print("tuseday")
case 5:
print("friday")
case 6:
print("seterday")
case 7:
print("sunday")
default:
print("error")
}

}
dayOfTheWeek(day: 4)
//Try out some different numbers here
//Don't copy the line below into Udemy

I still keep getting error. what's wrong with my code?

var aNumber =  Int(readLine()!)! 

// Function to determine the corresponding day of the week. It takes an integer day as a parameter
func dayOfTheWeek(day: Int) {
    
    switch day {
    case 1:
        print("Monday")
    case 2:
        print("Tuesday")
    case 3:
        print("Wednesday")
    case 4:
        print("Thursday")
    case 5:
        print("Friday")
    case 6:
        print("Saturday")
    case 7:
        print("Sunday")
    default:
        print("Error")
    }
}

// We call the function with the user input integer aNumber as the argument and it prints the day of the week to the console
dayOfTheWeek(day: aNumber)

////Don't change this
var aNumber = Int(readLine()!)!

func dayOfTheWeek(day: Int) {

//Write your code inside this function.

switch(day) {
case 1:
print("Monday")
case 2:
print("Tuesday")
case 3:
print("Wednesday")
case 4:
print("Thursday")
case 5:
print("Friday")
case 6:
print("Saturday")
case 7:
print("Sunday")
default:
print("Error")
}
}

This is how I did it, it was super fun.

var aNumber = 1 // you can insert your own number here

func dayOfTheWeek(day: Int) {
    
    let daysArray = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
    
    switch day {
    case 1...daysArray.count:
        print(daysArray[day - 1])
    default:
        print("Error")
    }
    
    
    
}

dayOfTheWeek(day: aNumber)
