What are you trying to accomplish here, more concretely?
My first thought is that you shouldn't implement the same function in both
a protocol extension and a conforming class. Why not just give them
different names and call the function from within the extension instead of
from the class? E.g.
protocol FooPro {
func _fooFunc()
}
extension FooPro {
func fooFunc() {
print("fooFunc default")
_fooFunc()
}
}
class FooClass: FooPro {
func _fooFunc() {
print("fooFunc FooClass")
}
}
let fc = FooClass()
fc.fooFunc()
