Day 35 - Times Table app crash help

Forums > 100 Days of SwiftUI

I've been stuck on this for days, and despite trying to read the code of other solutions, I can't figure out why my app crashes/hangs the simulator when I click the 'start game' button.

I'm starting to fear I have a big gap in my understanding as to what is going on with passing data between views. Sorry if this is something obvious, I hate asking for help as I feel like I should be able to figure it out by myself, but yeah, totally stuck without any obvious error messages from XCode or the simulator crash.

                    Text("10 Questions").tag(10)
                    Text("20 Questions").tag(20)

                Button("Start Game") {
                    startGame(selectedNumberOfQuestions, selectedTimesTable)

                // For testing purposes
                Text("Selected Times Table: \(selectedTimesTable)")
                Text("Questions Quantity: \(selectedNumberOfQuestions)")

In the GameView Body your missing a point on padding


Thank you so much Hector!!! You are a life saver :-)

PS I think its strange XCode doesnt flag the incorrect .padding() syntax.
