iOS Human Interface Guidelines

iOS Human Interface Guidelines

As planners, or any individual who needs to comprehend the reasoning behind successfully planning for different interfaces ; the need to draw from a pool of information on which topics and components coordinate each outline style and design is necessary.

This article aims to outline the human interface guidelines, as directed by Apple, trying to make them simpler to process and help all of us get in agreement, or similarly as a boost for a few.

Design Principles

As an app designer, the opportunity to deliver an extraordinary product that rises to the top of the App Store charts is an objective. Henceforth, to do so the need to meet high expectations for quality and functionality is a priority.

iOS design themes include the following determinants;

Design Principles

In order to maximize the reach; aesthetic integrity: How does appearance and behavior integrate with function, that is captivate with fun and engaging design or focus with subtle purpose-driven design.

3D Touch

3D Touch adds an additional dimension to touch-based interaction. It provides additional functionality and has different outcomes on various levels of pressure on the touch screen. The users don’t use new gestures, they discover intuitively by receiving feedback

Home Screen Interaction: 3D touch option on a home page displays in different views.

Peek and Pop: It peek allows you to preview an element by pressing it and can fill the screen. The preview disappears when you lift the finger and now you can swipe to reveal additional action buttons, thus results in giving user the control. It is also used in tables to view detailed information; this is consistently emphasised or not used so as not to confuse users.

Apart from that, always allow users to pop, that is, switch to the full view by offering the same response as if they tapped the item. It does not have elements that need to be interacted within the peek, as users will need to lift their fingers to use them.

Live Photos: Live photos can be enabled to allow people to see and hear the movements just before and after they were taken like a short clip.



The above picture illustrates that it provides action buttons when appropriate.



Similarly; it is not required for an open button for a peek – as seen in the above pictures. Peek shouldn’t be the only way to perform item actions. Not every iOS device supports this functionality.


The users must be able to authenticate in return for the value given to them. For instance; personalised experience and extra features. The sign in experience must be convenient and unobtrusive this should result in communicating the benefits of signing up such as personalised content, access to features and others. As illustrated in the below picture, it can be noticed that it should be easier for the users to be able to understand if sign in is required before downloading or not.



Data Entry

The quick and easily done data entry is satisfying to the users. Hence, it’s good to demonstrate a speed up data entry where possible so that users don’t abandon your iOS Mobile App. The various given choices wherever possible like offering the defaults and mechanisms that prevent having to enter data when it’s not necessary, all leads to a better user experience. The users should only be able to advance once they have entered the necessary information. To dynamically validate input fields- so they update automatically in relation to other information. The easier the better user experience;  people make entry choices in tables and pickers by sorting information logically or providing search functionality therefore produce a convenient function. For example: the use of mechanisms like placeholder text to show people how to meet the expectation in a text box.



There are many other iOS Human interface guidelines apart from the ones mentioned above that are to be taken care of by the developers or the designers. The elements like drag and drop/ feedback, file handling, first point experience and gestures, loading and modality, navigation, rating and reviews, settings, terminology, undo and redo and many others (Read more on:
