For which iOS version should I build my app? When I build for the latest version (11. x), the app does not run on devices with iOS 10.3 (for example, my iPhone 5C). Is it even possible to upload apps for older versions (iOS 10.3) to the store? Or do I always have to build for the latest iOS version? Can all users with older devices not download my app?
I look forward to your answers.
