Good news is coming from the hand of Jeff Verkoeyen, head of Google app design for iOS. the designer has confirmed via Twitter than these applications they will adopt UIKit, the native system kit for creating user interfaces**.
From brand experience to platform experience
So far Google apps for iOS (Gmail, YouTube, Google Maps, Google Photos …) they used Material Design guides, Seeking to standardize the user experience with Android applications. It makes sense: this way Google services would be used the same way across all platforms.
However, this has also been generating complaints from users over time as using Google apps on an iPhone is like suddenly going on to be using the interface of an Android. the experience does not fit with other iOS applications respecting Apple’s design guidelines, creating inconsistencies.
So Verkoeyen has valued the improvements that Apple has added to UIKit from iOS 14, and will prioritize seeking native experience higher quality on iOS above displaying the “Google experience”. This will result in a design more in line with iOS itself and improved performance.
The change is taking place right now, and Google has already started hiring professionals to carry it out. We should start noticing the changes over the course of that year, leaving a few months to go. Changing the interface of an application is no joke which can be done in a few weeks.
