How to use 6/5 Coordinator Pattern, PureLayout, & V2 Appointments Navigation & Architecture

Coordinator Pattern

(presented by @Austin Betzer)

The pros of introducing the coordinator pattern within the app.

• It removes the responsibility of navigation from the UIViewController to a new class known as the
• Makes A/B testing easier to produce and maintain.

PureLayout

(presented by @Austin Betzer)

The pros and cons of building UI programmatically vs using xib/storyboards. Presenting a potential framework that could be adopted making it even easier to use.

GitHub - PureLayout/PureLayout: The ultimate API for iOS & OS X Auto Layout — impressively simple, immensely powerful. Objective-C and Swift compatible.

Pros

• Components & code can become the most reusable
• You can take advantage of subclassing, unlike the limitations that are introduced by storyboards
• Managing animations becomes easier, you no longer have to create outlets for constraints.
• You can create explicit initializers, vs. having to use property injection
• The framework is commonly used and supported by the community
• Easier to manage merge conflicts

Cons

• There is a slight learning curve if you are unfamiliar with using programmatic constraints
• It’s far less visual, you might find yourself navigating through a few flows before finding the UI you need to modify.
• You can end up with a lot of UI code in your view

Proposed Navigation Structure

(presented by @Austin Betzer)

Today all the code that controls which view is presented is handled by the AppointmentDetailsVC. This view uses a UIContainerView and hides the subview based on what segmented control is displayed.

We propose to use a UIPageViewController, a UIController that Apple provides to do this exact thing. You no longer have to handle displaying views at the correct time and memory management.
