Jitsu: Open Source Real-time Data Collection

You can install with Cocoapods, Carthage, or Swift Package Manager.

Add the pod to your Podfile: pod 'Jitsu'

And then run: pod install

After installing the cocoa pod into your project, import Jitsu into your project.

Create a file named Cartfile in your projects folder. Add Jitsu to your Cartfile: github "jitsucom/jitsu-ios" "main".

And then run: carthage update --use-xcframeworks

Open Carthage/Build directory, and drag Jitsu.framework to your application targets “General” tab under the “Linked Frameworks and Libraries” section.

If your app can't find Jitsu, go to your target's build settings, and add $(SRCROOT) recursive to your Framework search path .

Then import Jitsu into your project.

1. Go to File > Swift Packages > Add Package Dependency
2. Paste the project URL: https://github.com/jitsucom/jitsu-ios.git
3. Click on next and select the project target
4. Don't forget to set DEAD_CODE_STRIPPING = NO in your Build Settings (https://bugs.swift.org/plugins/servlet/mobile#issue/SR-11564) **NOTE: For MacOS you must set the Branch field to jitsucom/jitsu-ios

After successfully retrieved the package and added it to your project, import Jitsu.

// Swift: 
import Jitsu

// Objective-C: 
@import Jitsu;

SDK is configured with JitsuOptions. You should pass your API key to it, and a tracking host, if you want to use custom host.

// Swift: 
let options = JitsuOptions(apiKey: "YOUR_API_KEY", trackingHost: "YOUR_HOST")
Jitsu.setupClient(with: options)

// Objective-C: 
JitsuOptions *options = [[JitsuOptions alloc] initWithApiKey:@"YOUR_KEY" trackingHost:@"YOUR_HOST_OR_NIL" logLevel: JitsuLogLevelDebug];
[Jitsu setupClientWith: options];

Telling SDK to track events. There are two options:

a) client can send an event as something conforming to Event protocol

// Swift: 
Jitsu.shared.trackEvent(_ event: event)

// Objective-C:
JitsuBasicEvent * event = [[JitsuBasicEvent alloc] initWithName:@"hi" payload:@{}];
[Jitsu.shared trackEvent: event];

b) or pass it as a name of event and Dict of event params.

// Swift: 
Jitsu.shared.trackEvent(_ name: "user pressed like", params: ["to_user_id: "NEW_VALUE"])

// Objective-C:
[Jitsu.shared trackEventWithName:@"Hi from Objective-C" payload: @{@"id": [NSUUID new]}];

Information about user is passed with events.

Use Jitsu.shared.userProperties or Jitsu.userProperties to manage user info. UserProperties consist of an anonymous user id and custom identifiers that you can set to the user.

anonymous user id: Jitsu automatically sets a UUID to any user, that is stored between launches. You can get it by Jitsu.userProperties.anonymousUserId.

user identifier: You can set your own identifier to user. You can access it it by Jitsu.shared.userProperties.userIdentifier. You can set new identifier with:

// Swift: 
Jitsu.userProperties.updateUserIdentifier("NEW_ID", sendIdentificationEvent: true)

// Objective-C:
[Jitsu.userProperties updateUserIdentifier:@"new identifier" sendIdentificationEvent:NO];

email: You can set email. You can access it it by Jitsu.shared.userProperties.email. You can update it with:

// Swift: 
Jitsu.userProperties.updateEmail("[email protected]", sendIdentificationEvent: true)

// Objective-C:
[Jitsu.userProperties updateEmail: @"[email protected]" sendIdentificationEvent:TRUE];

other identifiers: You can set additional user identifiers. You can access it it by Jitsu.shared.userProperties.otherIdentifiers. You can update it with:

// Swift: 
Jitsu.userProperties.updateOtherIdentifier(forKey: "my_key", with: "new_value", sendIdentificationEvent: true)

// Objective-C:
[Jitsu.userProperties updateOtherIdentifierForKey:@"my_key" with:@"new_value" sendIdentificationEvent:YES];

You can set multiple user properties:

// Swift: 
Jitsu.userProperties.identify(
	userIdentifier: "my_id",
	email: "[email protected]",
	otherIds: ["name": "Foo", "surname": "Johnson"],
	sendIdentificationEvent: true
)

// Objective-C:
[Jitsu.shared.userProperties identifyWithUserIdentifier: @"my_id"
						email: @"[email protected]"
					   otherIds:@{ @"name": @"Foo", @"surname": @"Johnson" }
				sendIdentificationEvent: NO];

You can reset all users properties. All the properties set before will be reset, and new anonymous_id will be generated.

// Swift: 
Jitsu.userProperties.resetUserProperties()

// Objective-C:
[Jitsu.userProperties resetUserProperties];

You can set properties that will always be added to events of certain types. You can add, change and remove context values. You can either add properties to certain event types or do not specify event type - then it will be added to all the event types. You can also set if you want context values persisted between launches. By default context events are not persisted.

// Swift: 
Jitsu.context.addValues(
	["age": 32, "codes": "Swift"], 
	for: ["event sign up"],
	persist: true
)

// Objective-C:
[Jitsu.context addValues:@{@"language": @"Objective-C"} for: @[@"hi"] persist:NO];
[Jitsu.context addValues:@{@"general": @"value"} for: nil persist:NO];

You can remove context values by calling

// Swift: 
Jitsu.context.removeValue(for key: "language", for eventTypes: nil)
Jitsu.context.removeValue(for key: "language", for eventTypes: ["hi"]])

// Objective-C:
[Jitsu.shared.context removeValueFor:@"age" for: nil];
[Jitsu.context removeValueFor:@"language" for: @[@"hi"]];

You can clear context when needed. It will not clear automatically gathered values (only update them).

// Swift: 
Jitsu.context.clear()

// Objective-C:
[Jitsu.context clear];

SDK automatically gathers some context values.

• device info: model, screen size, OS version
• app version, app name, sdk version
• system language
• voice_over: true if the user has VoiceOver on.

You can send an event from a screen in one line. This event will contain screen title and screen class as well as event data.

// Swift: 
Jitsu.shared.trackScreenEvent(screen: self, event: JitsuBasicEvent(name: "screen opened"))

// Objective-C:
[Jitsu.shared trackScreenEventWithScreen:self name:@"screen opened" payload:@{}];

Jitsu can do some tracking for you. You can set what to track when initializing SDK with JitsuOptions.

• Main app lifecycle events: shouldCaptureAppLifecycleEvents
• When app was updated or installed
• User opens a push notification: shouldCapturePushEvents
• App was opened from a deeplink. shouldCaptureDeeplinks. We pass the link in payload. Note: this method will not work if your app uses SceneDelegate. If so, you will have to track opening from deeplink manually in scene(_ scene: , willConnectTo session: , options connectionOptions: )

SDK can gather info about location. There are two modes which you can set in options. SDK uses the permissions that your app has, and would never ask user for permission by itself.

• trackPermissionChanges - SDK tracks location permission changes. We add current location permission status to the context, and send events when it changes.
• addLocationOnAppLaunch - If user granted access to location, we gather new location every time app launches and add it to the context.

// Swift: 
options.locationTrackingOptions = [.addLocationOnAppLaunch, .trackPermissionChanges]

// Objective-C:
[options setLocationTrackingOptions: @[@(LocationTrackingOptionsTrackPermissionChanges), @(LocationTrackingOptionsAddLocationOnAppLaunch)]];

Also there is a special event type method that allows to send location events easily:

// Swift: 
let event = LocationEvent(location: location, name: "left bike", payload: [:])

// Objective-C:
LocationEvent *event = [[LocationEvent alloc] initWithName: @"hi" location: location payload: @{}];

Jitsu doesn't collect any other sensitive data.

You can allow your users to disable/enable data collection.

// Swift: 
Jitsu.shared.turnOff()
Jitsu.shared.turnOn()

// Objective-C:
[Jitsu.shared turnOff];
[Jitsu.shared turnOn];

We send events Jitsu turned off and Jitsu turned on

You can set log level when initializing SDK with JitsuOptions .

// Swift: 
options.logLevel = .critical

// Objective-C:
[options setLogLevel: JitsuLogLevelInfo];

where JitsuLogLevel has values debug, info, warnings, errors, critical, none

1. You can set up your own mock of Jitsu with calling Jitsu.setupMock:. If you pass nil, we will create our own empty mock
2. Jitsu automatically tracks if your app is in Unit Testing mode. If so, it disables sending data to the backend and saving it to the database.

• Jitsu uses an internal queue to make calls fast and non-blocking.
• Jitsu doesn't send all events at once, they are sent in batches. SDK sends a new batch either when the batch reaches eventsQueueSize, or every sendingBatchesPeriod. Also, events are sent when an application enters background. If the app gets closed or crashes, events are sent on the next launch. You can manually set the number of events in the queue and time period.

Jitsu.shared.eventsQueueSize = 20
Jitsu.shared.sendingBatchesPeriod = TimeInterval(seconds: 10)

Also, you can force SDK to send batch immediately by calling sendBatch().
