TransitionKit is a small Objective-C library providing a block-based API for implementing state machines on iOS and Mac OS X. It supports arbitrary states and events with transition callbacks, NSCopying/NSCoding compliance, and runtime validation of misconfigurations.

Use cases

  • implement a state machine in an iOS app
  • model object lifecycle states like message read/unread
  • manage complex state transitions in Objective-C code
  • add transition callbacks and guards to app state logic
  • archive and copy state machines with NSCoding

When to choose

  • you are building an Objective-C iOS or macOS app that needs finite state machine semantics
  • you want a lightweight, dependency-free state machine library with block callbacks
  • you need strongly enforced transitions with runtime validation

When to avoid

  • you are writing Swift and prefer a Swift-native state machine library
  • your project no longer targets legacy iOS/OS X versions supported by this 2017-era release
  • you need distributed or hierarchical statecharts rather than simple flat state machines
