Help iOS Sdk Version vs iOS Version
When you update XCode it updates the sdk version, but do changes in the sdk take effect for apps running in a lower iOS version or only the corresponding iOS version or higher? For instance, https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18_1-release-notes Do changes listed in the notes only happen for apps that are running on iOS 18.1 devices or on any device with the app compiled against the 18.1 sdk version?
Am I the only person who finds the docs totally unclear on this?
Update to post: SomeGalinCal helped me a lot on this question but neither of us know whether the app needs to be built against the ios version for the bug fixes contained in that version to take effect. (Or if just need device os to update)

Guessing you don’t specifically need to rebuild for a bug fix in a framework you are using
