Regarding the BackgroundTasks

Is there a problem with this BackgroundTasks framework? I've been trying for a long time, but the randomly application worked properly. It runs every 15 minutes {request.earliestBeginDate = date (timeIntervalSinceNow: 15 * 60)} and show local notifications every 30 minutes successfully. Unfortunately, I again ran the project and is no longer working. why is that?
