EventTracker

EventTracker is an open-source Swift library that allows you to easily track and monitor multiple named events and their occurrences. The library provides a simple interface to register, update, reset, and evaluate events based on customizable conditions. It also includes support for logging and persistence through UserDefaults.

I use this in another library ReviewPrompter but it can be used to track any number of things when you want to perform some action when the user has done some event x number of times, e.g. Prompting them to purchase a premium subscription after they have used a feature three times.

• Track multiple named events with unique identifiers
• Set custom conditions to evaluate events
• Increase and reset event counts
• Evaluate whether an event has met its condition
• Check if an event is being tracked
• Retrieve event count and condition values
• Enable or disable logging
• Persist tracked events and their conditions using UserDefaults

The library is almost fully tested with 98.2% code coverage

To add EventTracker to your project using Swift Package Manager, add the following dependency in your Package.swift file:

dependencies: [
    .package(url: "https://github.com/ChristianFox/EventTracker.git", from: "1.0.0")
]

Don't forget to add EventTracker to your target dependencies:

targets: [
    .target(
        name: "YourTarget",
        dependencies: ["EventTracker"]),
]

Initialise an instance

import EventTracker

let eventTracker = EventTracker(isLoggingEnabled: true)

Begin tracking an event

eventTracker.trackEvent(forIdentifier: "event1", withCondition: 3)

Stop tracking an event

eventTracker.stopTrackingEvent(forIdentifier: "event1")

Change the condition for an event

do {
    try eventTracker.changeCondition(5, forIdentifier: "event1")
} catch {
    print("Error updating event condition: \(error)")
}

Increase the event count

do {
    try eventTracker.increaseEventCount(forIdentifier: "event1")
} catch {
    print("Error increasing event count: \(error)")
}

Reset the event count

do {
    try eventTracker.resetEventCount(forIdentifier: "event1")
} catch {
    print("Error resetting event count: \(error)")
}

Check if an event's condition has been met

if eventTracker.hasEventMetCondition(forIdentifier: "event1") {
    print("Event met condition!")
}

Check an event is being tracked

if eventTracker.isTrackingEvent(forIdentifier: "event1") {
    print("Event is being tracked!")
}

Check the number of times an event has occured

let eventCount = eventTracker.eventCount(forIdentifier: "event1")
print("Event count: \(eventCount)")

Check the current condition of an event

let eventCondition = eventTracker.condition(forIdentifier: "event1")
print("Event condition: \(eventCondition)")
