Here is one great text and you should see it and read it. https://hackernoon.com/dive-into-the-details-of-ios-11-is-apple-still-detail-oriented-fe70af065a7d How on earth they did this? Why? Was it too much for Apple? I know Apple from early days, but this? This is not Apple or maybe they lowered standards? Mail.app First let’s look at Mail.app in iOS 11. Like other native apps, Mail also introduces a new Navigation Bar with Large Title. However, Large Title in Mail, has extra left margin compared to the design guide example. Here we will use Search Bar as reference object. In design guide example, Large Title and Search Bar share same distance to the edge, but in Mail.app, Large Title clearly moves a bit right compared to Search Bar. Files.app Search Bar in Files.app also has some issues. Seems Files.app engineers used a non-standard Search Bar. From the picture below, compared to standard Search Bar in Settings.app, Files.app has a slightly smaller Search bar, and lighter font color. App Store.app iOS 11’s App Store has gone through a redesign and introduced similar style like Apple Music. However, in App Store’s Today tab, compared to Apple Music’s For You, the fonts of date are different as App Store uses a bold one while Apple Music uses a light one. And in Apple Music, “Wednesday” is followed by a comma but in App Store the comma is missing. Also comparison between these two apps. In Search page, touching Trending item in App Store won’t trigger a hover effect as feedback for touch, while similar action in Apple Music search page will trigger a hover effect changing background/foreground color of the item. In my opinion, Apple Music does it better and native apps should be consistent upon decision of hover feedback, regardless of having it or not. Besides, there’re still some miscellaneous issues among details. In App Store, open any app with banner image, slightly swipe from left edge to right (but not full swipe that will dismiss the app page). The banner section will render strangely after page bounces back: What do you guys think?
