Q1Domain Verified

In the context of UIKit's Auto Layout, what is the primary purpose of a "constraint priority"?

To define the animation curve used when constraints are updated.

To determine the visual order in which views are laid out on the screen.

To specify the relative importance of conflicting constraints, allowing the system to resolve ambiguity.

To enforce minimum or maximum dimensions for a view, regardless of other constraints.

Q2Domain Verified

When designing a complex UI in UIKit, what is the most idiomatic and efficient approach for managing state changes and updating the UI in response to those changes, particularly in a modern iOS development context?

Using `NSNotificationCenter` extensively to broadcast state changes and having individual view controllers observe these notifications.

Implementing a Singleton pattern for all shared state and accessing it directly from view controllers to update their UI.

Employing a Model-View-ViewModel (MVVM) architecture with data binding mechanisms or explicit view model updates to trigger UI refreshes.

Directly manipulating `UIView` properties within event handlers and relying on the run loop to eventually update the display.

Q3Domain Verified

Consider a `UITableView` where cells need to dynamically adjust their height based on their content. What is the most performant and recommended method in UIKit to achieve this?

Using `tableView.estimatedRowHeight` and ensuring the cell's content view has proper Auto Layout constraints that define its intrinsic content size.

Implementing `tableView(_:heightForRowAt:)` and calculating the height manually within that delegate method.

Manually updating the `frame` of each cell's subviews to match the desired height.

Calling `tableView.reloadData()` whenever the content of a cell changes.
