I thought I saw some Swift code that did this:
let someString : String?
if some things
{
// some stuff
someString = <a string from something>
// some other stuff
}
// use someString
But I can't get Swift 2 to let me.
Basically, I want to make someString available outside the scope in which it's
initialized, but I don't want its assignment to ever change after that. I could
do the former with var instead of let, of course, but I'd like it to be treated
as a let after the first assignment. Is that possible?
