[Swift-user] Re: Swift app question

[Mihael Hategan]

What the code says there is iterate through some list holding the
current iteration variable in "y" and then declare an entirely new
variable, also named "y", in the inner scope of the iteration an assign
it the value of some computation. Is this what you meant?

In other words variables in swift are single assignment. You can't
successively assign different values to the same variable in the same
scope.
