Relatively straightforward to write this, which usually has meant "no" to
adding something to the standard library. (Not that I agree with that measure.)

Let’s wait until the people at the other side of the big lake have had time to

That requires a for loop.
Functional programming lets you write for loops more succinctly.
Why can’t $0 not be used as a reference, like array[index] ?
I've checked, it’s not among t
Because you are (trying) to edit a copy.
To edit the value in the array itself use:
array[index].number += 1

Simple question: why can’t I edit a variable array with a functional method?
For example:
struct TestStruct
{
var number = 0
}
var array = [TestStruct](repeatElement(TestStruct(), count: 2))
array.forEach { $0.number += 1 }
