4.0.0

The new Finite offers you two new features: temporarily subscribing transitions and observing any transitions at once.

Use the new onTransitions(perform:) or subscribeTransitions(perform:) methods to observe all transitions.
Temporarily subscribeTransitions of your State Machines and bind the callbacks to the lifetime of your View Controllers. Just don't forget to store the subscription to bind self as weak or unowned.

Breaking Changes

• Requires Swift 5
• Previously passing Transition.nilTransition to StateMachine.onTransitions(like:perform:) did never trigger the perform handler and was therefore useless. Now it will always be triggered.

Additions

• Deprecated StateMachine.onTransitions(transition:perform:) in favor of StateMachine.onTransitions(like:perform:).
• The StateMachine.onTransitions(perform:) overload for StateMachine.onTransitions(perform:).
• Adds temporary observation of transitions subscribeTransitions(like:perform:), subscribeTransitions(perform:), subscribeTransitions(from:perform:), subscribeTransitions(to:perform:), subscribeTransitions(from:to:perform:). All return a ReferenceDisposable which needs to be stored as a strong reference. On deinit, the handler will be freed.

Upgrading to 4.0.0

First bump your dependency version of Finite to 4.0.0.
When you compile your project, you won't experience compile errors. Instead you will receive compiler warnings whenever you used StateMachine.onTransitions(transition:perform:). If there are no warnings, you already finished the upgrade.

In case you passed .nilTransition: this did never work. Your perform operation has never been called!
Starting from 4.0.0, .nilTransition operations will always be called.

In case you did not pass a .nilTransition, apply the fix-it and use onTransitions(like:perform:) instead.
