The iOS Contacts app needs group management support
For the longest time, the Contacts app has remained relatively unchanged, serving its simple functionality of viewing, adding, and removing Contacts. However, one of the core functionalities that’s remained absent until today is the ability to manage Contacts groups on iOS.
On macOS, and iCloud.com, you can manage your Contacts groups, add and remove contacts as you wish. However, on iOS, this functionality is nonexistent. I prefer having my family in one group, coworkers in a separate group, and services in another group. The inability to manage this stuff on iOS kind of gets in the way of keeping the Contacts list organized. I submitted feedback for this hoping it could be a feature that’s added in a future iOS release.
