Google Analytics（分析）屏幕跟踪Swift 3.0无法正常工作

Question

Google's code for screen tracking isn't working in swift 3.0 This is the code:

    let tracker = GAI.sharedInstance().defaultTracker
    tracker.set(kGAIScreenName, value: name)

    let builder = GAIDictionaryBuilder.createScreenView()
    tracker.send(builder.build() as [NSObject : AnyObject])

I am getting the following error: "cannot convert value of type NSMutableDictionary? to type [NSObject: AnyObject] in coercion". Any help please?

Answer 1

Cast to NSDictionary first. This works:

tracker.send(builder.build() as NSDictionary as [NSObject : AnyObject])
