Swift dynamic cast failure - AnyObject?! to String

1
votes

I've just updated to Xcode 6 beta 6 and I have a following problem with my code which was working before

let reminderSubject = reminder["subject"]
println("reminderSubject: \(reminderSubject)")
let tempTuple = (reminderSubject as String)

reminderSubject is of type AnyObject?! when I try to downcast it to String it crashes with "Swift dynamic cast failure" message. The value printed by println is: Optional(Hey its Test!)

So the question is how to correctly cast AnyObject?! to String in Swift?

Typically you'd want to check to see if there actually was an item with that key in your dictionary, and therefore use a path like if let reminderSubject = reminder["subject"] { ... }, which would execute only if your reminder had a subject, and make reminderSubject non-optional. You may want to re-think your approach here; if you start seeing lots of exclamation marks it's a bit of a clue you're not writing particularly Swifty code, in my opinion. - Matt Gibson
@MattGibson thanks for your insight - I'll take a look at this since my current solution is "ugly as hell" even for me ;) - pJes2

Ok I've done it with:

let tempTuple = ("\(reminderSubject!!)")
