Changing the min SDK of my existing app

Hi,

I have an app on the App Store which targets iOS 11.

I would like to use SwiftUI for a new version of my app, so I need to change my minimum iOS to iOS 13, but I don't want to alienate pre-iOS 13 users.

Will the App Store provide access (update or first install) to the earlier version for users who are not yet on iOS 13? Or will they forced to upgrade or blocked from using the app?

If it's possible to support both pre-iOS 13 and iOS 13 users, what do I need to do or is it automatic?
Users running iOS versions older than your deployment target will continue to be able to run whatever they currently have installed. And unless you go in and specifically disable the old version(s) in App Store Connect under the last compatible versions, they would be able to delete the app (or purchase the newer version on a newer device) and then reinstall whatever is the most recent version that was compatible with their device.

But if you increase the deployment target you won’t be able to offer any new updates for those users. They will only be offered versions that already exist in the store.
Thanks. That's what I was afraid of. <sigh>
