Guess the Flag day 21 Wrong Flags show up for Question?

Forums > SwiftUI

I have been able to create the functioning game however sometimes It will ask to tap flag for say " Nigeria" but none of the options of flags to choose will include the correct flag. Other times it will have the right flag included.

Thank you in advance.

Check this,

func askQuestion() {
        countries.shuffle()
        correctAnswer = Int.random(in: 0...3)
    }

You are asking to ask a question for 4 case , 0,1,2 & 3 But, your Button label is

ForEach(0..<3) {number in

Update the Int.Random to 0..2 and you should be ok.
