I think it would be better to keep both init methods, one with session configuration and one with session. What do you think?

[codeOfRobin]

That works too! Have the init with sessionConfiguration generate a URLSession in the init. Would you like me to add that to the PR?

[vadymmarkov]

Yes, please 😉

[codeOfRobin]

One problem now 😕, since both declarations look identical to the compiler,

the empty initializer confuses the compiler 😞

Any way you can think of to get around this? (also, need to fix that vertical_alignment thing that won't go away :/

[vadymmarkov]

It should work if you drop default parameter for session: URLSession and create it like Networking(session: .shared) when needed.

[codeOfRobin]

Done 😄

[vadymmarkov]

Great! Any idea why tests are failing?

[codeOfRobin]

@vadymmarkov I just tried running those tests locally. The test that failed on CI (NetworkingSpec.Networking___urlSession_didReceiveChallenge_completionHandler___with_NSURLAuthenticationMethodServerTrust__without_baseUrl__passess_valid_parameters_to_completion() passed over here :/

Could you try running it locally on your computer to see if you can reproduce it?

[codeOfRobin]

Wait a second, I noticed the tests are running on Xcode 9.4. Could that be a cause?

[codeOfRobin]

Got a branch with an Xcode 10.1 image in the .travis.yml: https://github.com/codeOfRobin/Malibu/tree/travis-new-image

Hi 👋 @vadymmarkov gentle nudge, was hoping you could take a look at this 😬
