To: David Sweeris <davesweeris@mac.com>This kinda works but because we pass a struct at:
the ‘garbage collection’ at:
doesn’t affect the original array.The passed-in array isn't going to get modified though, because you never change it. At least semantically speaking, arrays in swift are pass-by-value, so when you assign it to your struct's local storage and then later modify the *struct's* variable, only the local copy gets affected. If you want to mutate the passed-in array, you'll have to do it in the function you pass it to.
That’s what I am trying to solve with the inout parameter. AFAICU if I use inout, I can mutate the original array (with the remove(at:) call in the iterator.
