A super lite chronology tracker to save and navigate application states (or any data you want).
No dependencies, lightweight & fully portable.

Overview

The funcionalities of Tardis are intentionally cut to the bone to provide a basic (yet very effective) way to keep a chronology of the state in a Redux-like architecture.

• Create a Tardis instance

let stateTracker = Tardis<AppState>()

• Save snapshots of the application state (or any other data you want to track)

stateTracker.save(snapshot: appState)

• Make your application time-travel!

if stateTracker.hasPrevious {
    appState = stateTracker.previous()
}

if stateTracker.hasNext {
    appState = stateTracker.next()
}

appState = stateTracker.oldest()

appState = stateTracker.latest()

• Discard all snapshots and restart with new tracking

stateTracker.reboot(with: appState)

And that's almost all. Check documentation comments in quick help for more details about specific functions.
