How can I make sure everything is updated in time??

Yes, you can set your iPhone to automatically download and install software updates. Here's how:

1. Open the "Settings" app on your iPhone 
2. Tap "General"
3. Tap "Software Update"
4. Turn on the switch next to "Automatic Updates"

With this setting enabled, your iPhone will automatically download and install software updates when they become available, without you having to manually check for them. Note that you'll need to be connected to Wi-Fi and have enough battery life for the update to take place.
