jquery - Local Storage deleted in ios13

Question

We are using different concept like

1.localStorage.setItem("key","value");
2. preference.put("key","value");
3. memorypreference.put("key","value");
4. globalpreference.put("key","value");

But the stored key itself is deleted once we kill or destroyed the app from background task in iOS 13 device (iPad).

Surprisingly this data are not getting deleted(or retained) for same scenario in xcode 11.2 simulator(tested with iPad OS 13.2) and even lower version of ios devices.

Is there any work around for it?
