Well, I wanted to do this:
// Get the hero thumbnail…
let thumbURL: String?
for imgD in images
{
if let isHero = imgD["is_hero"] as? Bool where isHero,
let t = imgD["thumbnail_signed_src"] as? String
{
thumbURL = t
break
}
}
print("Thumb: \(thumbURL)")
But it complains that it's used before being initialized. I guess I want it to
initialize it to nil, then let me assign it once, then keep it constant.
