Hi,
I would have expected that the following code reports an error, because
of ambiguous function overloads:
infix operator ***: MultiplicationPrecedence
infix operator +++: AdditionPrecedence
func ***(x: Int, y: Int) -> String {
print("f1")
return ""
}
func ***(x: Int, y: Int) -> Int {
print("f2")
return 0
}
func +++(x: String, y: Int) -> Int {
print("f3")
return 0
}
func +++(x: Int, y: Int) -> Int {
print("f4")
return 0
}
let result = 0 *** 4 +++ 0 // prints f2 and f4
As far as I can tell, there are two possible overload resolutions: f1 + f3 or
f2 + f4.
I thought that these two solutions get an "equivalent score" and therefore
there would
be a compile error. However, that's not the case. Instead, the type checker
picks
f2 and f4.
So, I guess my question is, whether there is some rule, that prefers
operators, which have the same argument types and the same return type
or whether this is simply a bug.
Thanks and best regards,
