v1.3.0

Highlights:

  • First contribution from Eric Tang adding support for DispatchTimeInterval initialization of time-based interactions and operators.
  • New visualization tools for streams.
  • All gestural interactions can now be reactively enabled and disabled.
  • Transitions APIs are evolving as we begin work on components. View the roadmap for more details.

Behavioral changes

• defaultTransitionSpringTension and defaultTransitionSpringFriction's values have been swapped to match the actual default values for tension and friction. These values were previously incorrectly reversed.

• Operators that do not support Core Animation will no longer throw runtime assertions when receiving Core Animation events. We have an open issue to explore nicer handling of operators and properties that do not support Core Animation.

New features

Runtime

• MotionRuntime now allows you to retrieve interactions associated with a given target with the new interactions(for:filter:) API.

Example usage:

let draggables = runtime.interactions(for: view) { $0 as? Draggable }

Interactions

• PathTween, Tween, TransitionTween each have a new convenience initializer that accepts the DispatchTimeInterval enum, making it possible to specify explicit time units. Contributed by Eric Tang.

Example usage:

let tween = Tween<CGFloat>(duration: .milliseconds(300), values: [1, 0])

• Draggable, Rotatable, Scalable, and DirectlyManipulable now all conform to the Togglable type, meaning they can be reactively enabled and disabled.

Example usage:

draggable.enabled.value = false // Disables the interaction

Operators

• delay(by:) now accepts a DispatchTimeInterval enum, making it possible to specify explicit time units. Contributed by Eric Tang.

let delayedStream = stream.delay(by: .seconds(1))

• toString() transforms any stream into a string representation. This is part of our Reactive Controls milestone.

let stringStream = stream.toStream()

• visualize(in:) allows you to display a stream's values and changes in your app with a new visualization overlay that appears atop your runtime's container view.

Example usage:

runtime.add(tossable, to: view) { $0.visualize(in: runtime.visualizationView) }

API changes

Runtime

• MotionRuntime's add method now requires that targets conform to AnyObject. This will not affect any of the existing Interactions included with Material Motion. What this change means is that you can no longer build interactions that target non-object types.

Transitions

• TransitionController is now a pure Swift class type. This means TransitionController is no longer visible to Objective-C code. See #108 for our discussion on Objective-C support.

• TransitionController now exposes a transitioningDelegate property. TransitionController no longer conforms to UIViewControllerTransitioningDelegate.

// Before
viewController.transitioningDelegate = viewController.transitionController

// After
viewController.transitioningDelegate = viewController.transitionController.transitioningDelegate
