Apple UI Guidelines & Design Principles: You are darn sure that your app User Interface (UI) is as perfect as it can be. And you are darn sure that users will be downloading it, not in dozens (that’s so below you), but in tens and thousands. Good. Super Good.
But, don’t you think, you have taken your thoughts too far as an app maker. Because, before we talk about downloads and all, my simple question to you is: “Are your apps based on Apple App Store’s UI design fundamentals?
Ah! You haven’t bothered to look at them! Great! Then does all this optimism hold any meaning?
Forget about downloading, Apple can stop you dead in your tracks if you haven’t taken enough pains to comply with their basic UI design guidelines.
In fact, it’s crucial for both the mobile app developer and the Apple App Store reviewers to be on the same page, specifically for UI basics, if you really want to improve your chances of getting your app through the Apple App Store doors.
So, if you haven’t bothered to go through the Apple UI guidelines, the store reviewers won’t bother to look at your apps. Plain and Simple.

10 Basic Apple UI Guidelines
Here goes those 10 UI Design Basics Apple App Developers Shouldn’t Ignore.
1. Fitting Layout Formats
Ensure a layout that fits the screen of any iOS device. Users should access the basic content without any zooming or scrolling on any of the iOS devices, be it iPhone, iPad, or iPod.
2. Interactive Touch Features
Ensure to install touch features such as tap, pinch, and drag in your app. It not only helps people establish a personal connection with their devices, but they also get a kick out of manipulating the onscreen objects. And the feature should work the same way in all the apps they are using.
