Version 6.0.0
Screen time and engagement metrics
The tracker can now track screen engagement information, including the screen time and metrics for the amount of content viewed on the screen! Visit this demo to see it in action! This works nicely together with the Snowplow Unified dbt package 0.2.0.
- Add screen engagement tracking of time spent and list items scrolled on a screen (#851)
- Enable lifecycle autotracking by default (#852)
visionOS support
The iOS tracker now supports visionOS! Moreover, it provides new APIs to track visionOS events such as open and dismiss immersive space.
Local event store automatic cleanup
The tracker can now automatically remove old events from the event store in situations when requests are blocked due to ad blockers or in case of longer offline usage.
-
Add configurable limit for the maximum age and number of events in the event store and remove old events before sending (#860)
-
Expose event store from emitter controller to be able to remove all events from database (#834) thanks to @danigutierrezayuso
-
Remove the use of the FMDB dependency in SQLiteEventStore (#823)
Tackling duplicate events
We have improved the trackers to avoid sending duplicate events to the Collector by making requests serially and adjusting request timeouts.
- Add request timeout to network connection and configuration (#836) thanks to @danigutierrezayuso
- Make network requests serially in network connection (#846)
Batching improvements
The event batching algorithm has been improved to make it possible to make requests to the collector after a certain number of events accumulate in the event store (defaults to 1, but configurable to 10 or 25).
- Change default buffer option to single (#849)
- Flush events only when the buffer is full (#827) thanks to @danigutierrezayuso
Cross-navigation tracking
There is a new API to decorate outgoing links to other Web or mobile apps with user and session information.
- Add API to decorate link with user/session info (#819)
Improved concurrency model
We have reworked the internal concurrency model to be safer and more efficient.
- Improve concurrency model using a single internal dispatch queue (#820)
- Process tracked events on a serial background queue (#822)
iOS privacy manifest
We have added a SDK privacy manifest and made changes according to the latest recommendations from Apple.
- Add SDK privacy manifest file (#811)
- Remove available storage and total storage from platform context (#824)
- Add an option to override platform context properties (#865)
Other enhancements
- Return non-optional TrackerController instance from
createTracker(#847) thanks to @Kymer - Enable representing self-describing data using Codable structs (#844)
- Match BaseEvent entities API with Android tracker (#867)
Bug fixes
- Fix bundle path check to handle symbolic links (#858) thanks to @mylifeasdog
