Application Installed event not firing reliably

[timothycosta]

The Application Installed event is not firing reliably.

Expected Behavior

Application Installed should always fire for new installs.

Current Behavior

Application Installed does not always fire for new installs.

Possible Solution

Look at trackAppUpdatedInstalledEvent
The SDK relies on LAST_EVENT_TIME being nil in applicationDidFinishLaunchingNotification(notification: Notification). However, in my testing multiple events were fired prior to this method getting called. I never saw a nil value after deleting and re-running.

We noticed this after recently switching from the objective c sdk to this one. Our Application Installed events dropped almost, but not quite, to zero for versions with this sdk.

Steps to Reproduce

1. Delete app
2. Reinstall and run
3. Send events early in the app lifecycle

Environment

• SDK Version: 1.9.3
• OS Info: 18.0
