Problems with Async NSURLSession calls in Playground

Question

I'm trying to implement a custom Google search in IOS. For testing, I'm trying to test the request in a Playground. My search URL works fine in the browser (chrome), however in the playground the completion block isn't firing and I'm getting this in the console: (even after restarting Xcode)
