In the lines var body: some View {, in the ContentView struct, multiplicationcheck struct and additioncheck struct, I'm getting the error The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions. I understand why this is happening, but not how to fix it.
In the line var body: some View { in the divisioncheck struct, I am getting the error Type '()' cannot conform to 'View'. I don't understand why this error is happening.
If you could help me fix this, that would be great. Thanks!
The second error may have the same origin than the first.
To check for this, just add return EmptyView() on both and see what you get. Like this:
struct divisioncheck: View {
var body: some View {
if (startgame == true) {
let confirmation = checkanswer(guess: username, aanswer: answer1 as! Int)
moreText = confirmation
}
didfunc = genquesdivi()
answer1 = didfunc[0]
mainquestion = didfunc[1] as! String
username = ""
startgame = true
}
return EmptyView() // <<-- ADD THIS in all the View you defined, such as divisioncheck, additioncheck…
}
Of course, you will have to return whatever view is meaningful for your app.
Note: In Swift, if startgame is Bool (not optional Bool?), then you may simply write:
if startgame {
instead of
if (startgame == true) {
