Protocols - need to use [Any]?

I'm currently on the "Protocols as Types" video, and when I follow along, I get to the line of code where we declare the ingredients array.

When use the same code as Pasan, I get an error:

"Heterogeneous collection literal could only be inferred to "[Any]"; add explicit type annotation if this is intentional"

and Xcode suggests changing that line of code to:

let ingredients = [strawberry, chocolateMilk] as [Any]

Does anyone know why this would occur? Perhaps something changed with the new versio of Xcode?

Thank you in advance!

This is because Swift wants for you to add explicit type annotation if this mixing array is intentional. You can check more information in here
