Swift 3 '[UIApplicationLaunchOptionsKey : Any]?' is not convertible to '[String : NSString]'

I have a TVOS app that has been converted form Swift 2 to Swift 3 and I am getting the following error. I am unsure how to silence it.

'[UIApplicationLaunchOptionsKey : Any]?' is not convertible to '[String : NSString]'

It is showing up in this piece of code

appControllerContext.launchOptions["BASEURL"] = AppDelegate.TVBaseURL

        if let launchOptions = launchOptions as? [String: AnyObject] {
            for (kind, value) in launchOptions {
                appControllerContext.launchOptions[kind] = value
            }
        }

enter image description here

You'd better work with [UIApplicationLaunchOptionsKey : Any] as it is.

How is this?

    if let launchOptions = launchOptions {
        for (kind, value) in launchOptions {
            appControllerContext.launchOptions[kind.rawValue] = value
        }
    }

UPDATED

Seems the type of the property launchOptions of TVApplicationControllerContext is [String: Any], so you have no need to cast with as AnyObject.

try this code please and tell me what happen.

appControllerContext.launchOptions["BASEURL"] = AppDelegate.TVBaseURL

        if let launchOptions = launchOptions as? [String: Any] {
            for (kind, value) in launchOptions {
                appControllerContext.launchOptions[kind] = value
            }
        }
