Why will this code not compile?
func someFunction(a: Int) -> Bool { return a }
By my knowledge there is literal type (instead of Bool it should be Int) mentioned mistake . Can anybody explain me better what is mistake here.

return a
}
- we're saying this function takes a parameter
a
of typeInt
- we're saying this function returns a Bool with
-> Bool
- we return
a
, which is of typeInt
. So we're breaking the contract we set up where we said we were going to return aBool
