I'm reading this in the release notes of Xcode 13:
The Xcode 13 release supports on-device debugging for iOS 9 and later(...)
source: https://developer.apple.com/documentation/xcode-release-notes/xcode-13-release-notes
Now this may sound like a stupid question, but does this mean that iOS 9.0 is the minimum iOS Deployment Target we can choose from in Xcode 13?
Yes.
The simplest way is to try it...
I created a new iOS project.
The "Deployment Info" dropdown shows values from:
• iOS 15.0
to
• iOS 9.0
And that's it. Nothing earlier than 9.0
Personally, I would have believed Apple in the first place, but there's no harm in double-checking ;-)
