Tim, iOS has always been known for it’s user interface, until recently. Your new take on notifications have not only made them very loud, and unsettling, but do not flow with the entire look and feel of Apple:
See that white background? While you’ve done a good job of highlighting the content, it breaks continuity. There was nothing wrong to start with. The way notifications used to render on my iPhone was simply perfect! The content did not need to be highlighted the way you’ve done so in iOS 10. I really loved iOS for not cluttering my life, and making it simpler, compared to Android (the new style does look like inspiration from Android, doesn’t it?).
Comparing this to iOS 9, what you’ve lost is absolute ingenuity:
I’ve been using the beta version of iOS 10 for a little more than a few hours now, and the Today screen has also been ruined. Oh! I almost forgot – what you’ve done to the control centre is horrible. Do you know what this reminds me of? It reminds me of the Red Wedding – Lord Bolton murdering the King of the North, Robb Stark. That was truly gruesome, wasn’t it?
Tim, iOS 9 was the epitome of creation.
I truly hope that this letter talks solely about iOS 10 preview, and that it doesn’t speak for iOS 10 final.
