I'm trying to extend a Swift array to add a method containsValue which will return a bool if a given value exists.
extension Array
{
func containsValue(value: T) -> Bool
{
for item in self
{
if item == value
{
return true
}
}
}
}
But this gives the following error on the if item == value line.
Cannot invoke == with an argument list of type (T, T)
How can I compare the given values in a generic way so I can add this extensions to my array?
edit: I found a global function contains which does the trick. But I am still curious, how could I achieve this with the generics?
