Is there no default(T) in Swift?

Question

I\'m trying to port the Matrix example from Swift book to be generic.

Here\'s what I got so far:

struct Matrix {
    let rows: Int, columns: Int

There isn't. Swift forces you to specify the default value, just like then you handle variables and fields. The only case where Swift has a concept of default value is for optional types, where it's nil (Optional.None).
