Ambiguous use of 'subscript'

[safetylab]

When I try to add your example in my code I have

let cellDescriptor = cellDescriptors[indexPath.section][indexOfVisibleRow] as! [String: AnyObject]

Ambiguous use of 'subscript'

How can I fix this?

You can fix this error by splitting the expression and casting each subscript to appropriate type, like this:

 let array = cellDescriptors[indexPath.section] as! NSArray
 let dict = array[indexOfVisibleRows] as! NSDictionary

Here dict is your dictionary of type (String: AnyObject)

Swift is a strongly typed language and that is why you are getting this error
