URLSession produces '()', not the expected contextual result type

Question

Any clue why am I getting error "'URLSession' produces '()', not the expected contextual result type 'URLSession'" for the below line -

internalSession = URLSession(configuration: URLSessionConfiguration.default)

I'm using latest Xcode and swift 3. I have found similar questions & answers on stackoverflow and tried them but they didn't have working/accepted answers.

Please help.

请检查您的 URLSessionTaskDelegate 或 URLSessionDelegate 的委托方法，并尝试按照 swift 3 进行匹配。这对我有用。
