iOS Question When will xCode 26 become mandatory?

[Filippo]

Hi,

from what date will app submissions only be possible with Xcode 26?
I don't want to switch to Xcode 26 so quickly because many of my customers are still using iOS 12-15.

Thank you in advance for your reply.

I should have searched beforehand. Here is Google's answer:

When will xCode 26 become mandatory?


Xcode 26 will become mandatory for App Store submissions in
April 2026, when all new submissions must use the iOS 26 SDK (which requires Xcode 26 or later). This deadline applies to all platforms, including the watchOS 26 SDK, which will also require a 64-bit architecture. It is recommended to update to Xcode 26 well before the April 2026 deadline to avoid submission issues.

• App Store Submission: As of April 2026, all new app submissions to the App Store must be built with Xcode 26 and the iOS 26 SDK.
• watchOS: watchOS apps will also need to be built with the watchOS 26 SDK and have 64-bit support included.
• Preparation: It is crucial to prepare and transition your build workflows to Xcode 26 before the April 2026 deadline to prevent build failures and submission rejections.

B4i v10.0 is compatible with older versions of iOS, at least iOS 15+.

B4i v10.0 is compatible with older versions of iOS, at least iOS 15+.

Then I won't be able to use my iPhone 6+ for development anymore.
But anyway, I still have 3 devices:
1) iPhone X, iOS-Verison 16.7.12
2) iPad (5. Generation) , iPadOS 16.7.12
3) iPad-Mini (6. Generation), iPadOS 26.1

However, the “#MinVersion” must not be less than 16 for development, otherwise I cannot test anything.

This issue was fixed. I guess that you are using a local Mac.
See this post:

B4i v10.0 has been released!

I'm happy to release B4i v10.0 :) B4i compilation process has been rewritten from scratch based on Apple's latest methodology. All native libraries were rebuilt and most external dependencies were updated with latest versions. B4i libraries are now compiled as xcframeworks and are compatible...
