safari for iphone XR

Restore a built-in app that you removed

1. On your iOS device, go to the App Store.
2. Search for the app. Make sure that you use the exact name of the app. Find the correct name of built-in apps.
3. Tap  to restore the app.
4. Wait for the app to restore, then open it from your Home screen.

If you have an Apple Watch, restoring an app to your iPhone also restores that app to your Apple Watch.

Apps - Remove built-in Apple apps from the Home screen on your iOS device or Apple Watch

With the new range of iPhones all apps have been made deletable.

That is incorrect. While many apps are deletable, there are still several that cannot be deleted. Safari is one of those apps. It cannot be deleted, and as such cannot be downloaded from the App store. Deletable Apps have an entry in the app store to be able to download them after they have been deleted. Safari does not.

If its not in a folder, or on another home screen, then its almost certainly restricted.

With the new range of iPhones all apps have been made deletable. No use doing a reset as if not in the apps column it won't reappear. Because people want to use 3rd party software they wanted the option to delete unwanted app to avoid clutter. Like get rid of Stocks Icon.

Safari on an iPhone cannot be removed/deleted.

Try Settings > General > Reset > Reset Home Screen Layout.

Safari is not a deletable App. As such it does not appear in the App Store.

If its not in any home screens, and is not in any folders, go to Settings->Screen Time->Content & Privacy Restrictions->Allowed Apps, and make sure Safari is not turned off.
