Recently, Instagram broke the resolution for both devices last month and finally Instagram is now optimized for users using iPhone XR and XS Max again after rolling out support for the iPhone XS Max and XR displays back in October.
Basically due to some compatibility and crashing issues, Instagram had to roll back to an older version of Xcode that they used to compile the app, which turn meant that the app was on longer optimized for Apple’s larger iPhones.
Instagram has since addressed the issue where they have issued yet another update where the app is now optimized for those iPhones again but also requires Instagram users to be running iOS 10.
Instagram did not make any announcements of sorts but if you are an Instagram user and own either the iPhone XR and iPhone XS Max, you’ll notice that things look “small” again.
Due to it had to do with a large number of Instagram users still being on iOS 9 which caused problems with the Xcode and the iOS 12 SDK.
From what we’ve been able to gather from sources, the Facebook team had to distribute the app with an older version of Xcode because of a common crash that can occur with apps compiled using the iOS 12 SDK but running on iOS 9, a system version which a large number of users of Instagram are still running.
Fortunately, Instagram has now fixed the problem for XS Max and XR users with optimized resolutions being seen again with the latest version of the app. On the downside for any users still on iOS 9, Instagram now requires iOS 10 or later.
