1. you must use current Xcode to submit to the App Store
2. Current Xcode only supports a short list of the most recent iOS SDKs as targets
3. Therefore you can’t make a build with an older Xcode to submit, and you can’t make a build that supports say, iOS 15, with current Xcode.
The video highlights a complete hack which can for now be used to make builds that target older SDKs, but Apple could change their systems to break that at any time, and in fact the latest iOSs don’t use these device support files that he shows are the key to the hack. So while you can do this now for old iOS, when 26 is too outdated for Apple to want you to target, this hack won’t work to bring it back.
This video was very informative on how Apple deliberately blocks developers’ ability to update an app without removing support for older iOS and an unsupported undocumented workaround the creator has noticed which at least momentarily works to work around it:
Your app must run on iOS 18 but you can drop features to get it to support as old of an iOS as you want.
That’s not true, watch the video here to see why not: https://youtu.be/WXqVV8_GORE

No you can
https://developer.apple.com/support/xcode/ the iOS 26 SDK can target iOS 15 or later
Sorry. I meant iOS 14, then
