No.1: Follow Design Guideline Charted by Apple

Apple has issued strict guidelines for app design too. Strict means follow the design conventions. For instance, iPhone app developers can modify a particular design element’s style to enhance the look-n-feel. Still, they cannot change the expected function of the element altogether. Obeying the rules and regulations of Apple can speed up the approval process and improve user experiences.

No.2: Design Intuitive App UI

Whether you design a standard app or highly customize the app, keep the design intuitive, so you need not direct the users to tutorials or apply onboarding techniques. Keep UI simple with native user experiences to provide users comfort. Keep visual appeal intact without disturbing UX.

No.3: Draw a Complete Flow Chart

Plan the app design by drawing a flowchart of the app. Consider the basic navigation framework first before designing other functional blocks or modules. Run guerilla UX tests on the planning prototype.

No.4: Easy to Navigate Design

The navigation bar is an excellent way to provide info regarding the UI. Keep design convention at the center to make navigation easy. For instance, keep the back button/icon at the left while the menu, profile, and action buttons on the right side of the navigation. You can customize the background and color of the navigation bar, but keep it blur or semitransparent to make the text behind it visible.

No.5: Design UI Responsive

Apple used to keep backward compatibility of iOS for limited previous versions of devices. Therefore, fragmentation issues are limited with design adaptations. However, it is the best way to keep the adaptive design for your custom iPhone app so it can scale up or down with old and upcoming iPhone devices. X-code and Sketch-like tools provide clues for design constraints, so follow them. The iPhone versions usually comprise four different resolutions, so design the app in a responsive way where layouts expand on resolutions but never scale on dimensions. For instance, the navigation bar scales on width but never on height, and element with it remain the same in proportions.

No.6: Design for Touch Gestures

If the iPhone app UI designer used to design UI for the pointing devices, the same will not work for touchscreen design. Touch gestures require entirely different approaches, such as needs spaces between the active elements that can allow a big thumb to operate without overlapping anything. Similarly, design conventions also different from pointing devices like a sweep, tilt, and so on.

No.7: Design Content

Readability of content is vital to any app success, so keep texts of iPhone app screen readable by selecting appropriate font size and type. Test it frequently with different iOS and iPhone devices. Place the control in the adjoining area of the relevant content to avoid confusion for users.

The status bar is essential to design elements for iPhone app users because it keeps users informed regarding many vital things. Include icons or elements for the time, battery status, network signals, and so on. Text or icon on the status bar could be in black or white or colors but must be in contrast to background color for optimum visibility.

No.9: Design Toolbar

The toolbar is essential for app functioning. Therefore, grab enough screen real estate for toolbar elements such as action buttons like ADD, EDIT, DONE, DELETE, DO, UNDO, and screen status. If your toolbar is exhibiting tools in the context of UI or modules appear on the screen, you need to provide enough space to cover the maximum elements.

No.10: Design Tab Bar

Tabs are an excellent way to provide a comprehensive but custom navigation scheme for your iPhone app. Try to avoid designing the Hamburger menu when significantly fewer items to display. The design is standing out the menu with clarity in design and style. Icons-only design approaches are not promising because, without explanatory texts, users may be misguided or confused when a less popular symbol has placed. If you want to use an icon, try to use the outline instead of a filled icon to make it subtle in design.

No.11: Design Progress Bar

A progress bar displays the progress of the action taken and keeps users engaged and informed that something is going on and the app is not hanged or stop functioning. It is valid in the case of loading screens. Similarly, the progress bar also keeps users informed regarding the process they have initiated to checkout and displays the present status of the process by displaying steps or stages of the process.

No.12: Design Buttons & Texts

On the touch screen, designing buttons like action elements become tricky. The standard size of the button is 44 points. Similarly, display an on-off toggle button with design conventions. For small text, 12pt is enough. For body text, it requires 17pt, while for titles, it should be 20pt.

No.13: Prioritize Table View

The list view of content requires a table view, so it is primary and customized according to the content it has to display. App designers can use various preset styles and accessories at the basic level of design of table view. It can be designed to group the cells with the title above and the description below.

No.14: Use Modals

Various UI modules or models are available for iPhone app UI design, such as the alert dialog box, which communicates important info and entices quick actions. Activity dialog box helps to share the content using texts, links, and photos leveraging various iOS features, including Bookmark, Favorite, Airdrop, and social media like Facebook, Twitter, etc. Design full-size modules for a bit lengthy info and make them appear on the screen from the slide, flip, fade, or page animation schemes. Of course, keep design elements like the cancel button on all modules to save frustrating experiences for app users.

No.15: Optimize Images

Images must be optimized for memory size in KBs instead of MBs to load the screen elements quickly and smooth the app interactions. Tiny screens of iPhone devices require different resolutions of the images and need to make its retina display compatible. Keep image aspect ratio intact while resizing it to avoid distorting appearance. Similarly, keep image clarity prominent to display on tiny screens.
