Ambiguous use of Subscript Swift iOS

Since updating the latest Xcode, I've started to get the following error occurring "Ambiguous use of Subscript" related to this piece of code;

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        var cell = tableView.dequeueReusableCellWithIdentifier("postsCell") as! CustomTableViewCell!
        if cell == nil {
            cell = CustomTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "postsCell")
        }
        let dict:NSDictionary = arrPosts[indexPath.row]

        if let postResourceName = dict["resource_name"]![0] as! String? where !postResourceName.isEmpty {
            cell?.customPostTitle?.text = String(htmlEncodedString: postResourceName)
        } else if let postTitle = dict["title"]!["rendered"] as? String {
            cell?.customPostTitle?.text = String(htmlEncodedString: postTitle)
        }

Specifically on this line;

if let postResourceName = dict["resource_name"]![0] as! String? where !postResourceName.isEmpty {

I'm quite new to Swift, I believe this relates to the lack of detail around a variable type which is why the error is being thrown. But I'm unsure as to what the code should be.

Any pointers?

Regards, Michael

Swift compiler gives you that error because is does not know what objects do you have as values in you dictionary, so when you do dict["resource_name"]![0] you want to access the first item of the array contained in the dictionary as a value. But you never tell that your values are arrays so the type of the values is AnyObject. You could specify that you have Array in your dictionary by replacing

let dict:NSDictionary = arrPosts[indexPath.row]

with

let dict = arrPosts[indexPath.row] as [String:[String]]
