I'm developing an sms based Ionic IOS app. And we are using Signal-R events to update the app in real-time. In Android, the app is updating real-time when it's opened and even in the background. But in the IOS app, it's not working when the app is in the background. (This is a capacitor ionic app)
What may be the issue?
You need to use the Capacitor background task plugin. Also make sure to read the guidelines. Apple currently allows a maximum of 30 seconds after an app has closed to run any bg task, so you have minimal time.
