SOLVED: Day 13: some Equatable - error message

Forums > 100 Days of SwiftUI

I enter the code

*import Cocoa // How to use opaque return types

func getRandomNumber() -> some Equatable { Int.random(in: 1...6) }

func getRandomBool() -> some Equatable { Bool.random() }

print(getRandomNumber() == getRandomBool())*

and then is get the error

error: MyPlayground.playground:12:28: error: cannot convert value of type 'some Equatable' (result of 'getRandomBool()') to expected argument type 'some Equatable' (result of 'getRandomNumber()') print(getRandomNumber() == getRandomBool())

Any tip


Hi! But how can you compare an Int type with Bool type in the end of the day? Does 2 equal to true or false for example?


hey, this is sample of the day 13. in the associated video the comparing results works fine but I got the error message. I can not see why it is so. I use the latest version of macOS 14.


@Marcel wonders why this code doesn't work?

print(getRandomNumber() == getRandomBool())

He insists that this is what @twoStraw uses in Day 13 lessons.

However, I see that @twoStraws actually wrote this code:

print(getRandomNumber() == getRandomNumber() )  // <-- This is different from @Marcel's code.
