Hello Apple Developer Community,
We have an enterprise app that was originally developed using Xcode 10 and Objective-C. The app has been running smoothly on previous iOS versions, but with the upcoming release of iOS 26, we are concerned about potential compatibility issues due to the age of our development environment and possible deprecations in the iOS SDK.
Our Situation:
App Type: Internal enterprise app (distributed via Apple Developer Enterprise Program)
Development Environment: Xcode 10, Objective-C
Current Status: App works on iOS 18; not yet tested on iOS 26
Distribution: Not on App Store; internal use only
Questions:
Are there known compatibility issues for apps built with Xcode 10 and Objective-C when running on iOS 26?
Are there specific deprecated APIs or changes in iOS 26 that we should be aware of?
What are the recommended steps to test and validate enterprise apps on the latest iOS beta?
Is it mandatory to rebuild the app using a newer version of Xcode for iOS 26 compatibility, or can we continue using our existing build if it passes testing?
Any advice on best practices for enterprise app migration or update planning?
Additional Info:
We plan to test the app on iOS 26 beta devices soon and will share any specific issues encountered.
If there are official Apple resources or documentation addressing these concerns, please point us in the right direction.
Thank you in advance for your guidance!
