Swift 3 - Type 'Any' has no subscript members

Question

I upgraded my project to Swift 3 and came across this error:

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

I got an error on this line:

Type 'Any' has no subscript members

How exactly do I fix this? I'm not sure how to go about it. I tried converted the first part to an NSDictionary, then it tells me that indexPath of type IndexPath cannot be converted to NSIndexPath.

Answer 1

NSIndexPath has been replaced with IndexPath, so that part should become simply

cellDescriptors[indexPath.section]

For the rest of the problem, how have you defined cellDescriptors? It may be easier to do this as a two-step process

let firstPart = cellDescriptors[indexPath.section] as! MyCellDescriptor
let cellDescriptor = firstPart[indexOfVisibleRow]
