As per apple latest requirements 2020 April all apps should have base SDK 13.0 does this mean we need to set deployment target to 13.0 or just build app using Xcode 11.x and leave existing deployment target?
My current app min target is 11.0 but still working on iOS 13.0 devices? Do I need to change any thing for future releases.

The latter. The keyword is "SDK". You just need to use/build your application using the SDK. You may set your deployment target to as low as you can or whatever your current Xcode allows the lowest/oldest.

No. Your minimum target is literally the minimum target. It means that any iOS version below that target won't be able to install/run your application. But any higher iOS version will be definitely supported.
