Hi everybody.
My question is about the minimum version of XCode of an app that is already distributed via App Store.
I have an old app built with XCode 7. The app is published in the App Store.
Is there a deadline for this version of XCode?
If i don't upgrade the app is it possible that Apple block this app on the App Store because too old or because the app is built with a too old version of XCode?
Thanks in advance
See: Supported Xcode and Application Loader versions ...for what ASC currently accepts for minimum Xcode & iOS.

Not upgrading can risk that app not being supported on current devices with current iOS. How that risk manifests itself depends on your app, not specifically which version Xcode was used.
I guess depending on the nature of the app, you MIGHT get email from Apple at some point telling you to upgrade your app within 30 days or it will be removed from the App Store. That happened to one of my apps recently that hadn't been upgraded in three years. It was relatively easy to fix all the deprications and rebuild it using the latest XCode.
One challenge could be you may have developed the app in say, Swift 2 back in 2015 or so.
Then if for some reason Apple have taken your publish app down from the store, you may find it impossible to publish it back again in its Swift 2 guise.
Newer xcode versions than xcode 7 likely will not recognize Swift 2 code but request you to convert your code to a newer Swift language incarnation.
This requires gradually installing newer xcode versions as you keep converting to newer Swift levels, so that you step by step get access to a converter that help you convert your source code to yet a newer Swift language stepping and enable the code usable on that newer xcode version.
If you are successful in doing so all the way up to xcode 11 you may find yourself with Swift code that you cannot recognize as having written yourself(!). All may seem obfuscated after all the steps from 2,3,4 to Swift 5.
And during the conversion effort earlier xcode versions may not execute at all on your latest macOS version.
So you may need more than one Mac to run the multiple xcode versions required along the way.
In case of one app I wrote back in 2015 I found it was better to stay with the Swift 2 app and xcode 7 on an older macbook (with older OSX) and study and refresh myself on that original code flow. Then create a brand new project on xcode 11 on a recent macbook and manually reproduce the app there from scratch in Swift 5.
Yeah, I don't use Swift (Objective-C only) so Swift compatibility may be a factor.
