Watched Swift Talk #142 Flow Testing with Protocols.

Read post Safely supporting new versions of Swift. Usually I change Swift version ‘In one big go’ as it described in the post.

Read iOS Responder Chain: UIResponder, UIEvent, UIControl and uses. Reminds that very long time ago I wanted to experiment with inputView to check what else can it show except UIPickerView. Look into UIResponder shows up a lot of new stuff like inputAssistantItem appeared in iOS 9, inputViewController and inputAccessoryViewController in iOS 8. Didn’t get part with implementation of CoordenableViewController. Otherwise post was an interesting reading.
