Good afternoon, all!
I was wondering if there was a timeline for when the App Store and/or TestFlight will drop support for Swift 5?
I know Swift 6 was released last year and historically App Store requires a certain SDK minimum for upload. I was wondering if any SDK update was on the docket that would effectively force applications onto Swift 6?
Looking at past releases, I had estimated mid to late 2026, but I wanted to confirm?
Swift 4
Released September 2017
Became the default SDK in Xcode 9
Strongly "encouraged" via the iOS 12 SDK in late 2018
Essentially "required" by early 2019
Swift 5
Released March 2019
Became the default SDK in Xcode 10.2
Strongly "encouraged" via the iOS 12.1 SDK in early 2019
Essentially "required" by late 2020
Swift 6
Released June 2024
Became the default SDK in Xcode 16
Strongly "encouraged" via the iOS 18 SDK in April 2025
**Essentially "required" by mide-late 2026 ?? **
Thank you in advance!
