Release notes of Xcode 26.2 https://developer.apple.com/documentation/xcode-release-notes/xcode-26_2-release-notes state that Swift 6.2.3 is shipped with it.
But when trying to check the Swift version with
#if swift(>= 6.2.3)
it returns false.
Running swiftc -version returns
swift-driver version: 1.127.14.1 Apple Swift version 6.2 (swiftlang-6.2.3.3.2 clang-1700.6.3.2)
As you can see, there is a mismatch between the marketing version "6.2" and the build version "6.2.3.3.2".
Being able to check for the 6.2.3 version is important for my team, because we are impatiently awaiting the change to the tabviewbottomaccessory modifier
https://developer.apple.com/documentation/swiftui/view/tabviewbottomaccessory%28isenabled:content:%29
so that it can be hidden when not needed. Without this fix we have the issue that the accessory shows even without content in iOS 26.1.
