AnyObject? does not have a member named 'subscript' swift

Question

I am new to swift. I want to get options in

fields: [{ config: { options: [{a: "one", b: "two"}] }}]

I have tried the following code but it brings an error "AnyObject? does not have a member named subscript".

my code

Looks like Options is a dictionary. not an array. – Leo Dabus Apr 22 '15 at 02:08 — Leo Dabus, Apr 22 '15 at 02:08
options is array of dictionary. – limmouyleng Apr 22 '15 at 03:12 — limmouyleng, Apr 22 '15 at 03:12
so you should cast as [AnyObject] – Leo Dabus Apr 22 '15 at 03:14 — Leo Dabus, Apr 22 '15 at 03:14

AnyObject? is really Optional<AnyObject>, and subscripts are not defined on the Optional type, however, I tried your code with a simulated fields dictionary and I had no issue, so may be your example has context not expressed here? Try making it ... as? AnyObject { rather than ... as AnyObject! { to see if that makes any difference. Also, simply quitting and reopening Xcode has shown to fix many of these types of issues :-)

I tried this and it works.

if let config: AnyObject? = fields[i]["config"] {
          if let options: AnyObject? = config?["options"] {
            println("options : \(options)")
          }
        }
