What is UI design? Understand user interface design and its role in creating a captivating user experience. Do you know why the notifications reminder on most mobile apps are red in colour? Or why spam pop-ups have the ‘caution’ icon? Or project management apps like Asana have a flying unicorn when you mark a task as complete? Because each of these things evokes a specific and intense emotion in the user — attention, fear and accomplishment respectively. Evoking these feelings, my friend is what is UI design. Let’s begin at the beginning.
What is User Interface?
User interface definition is simply: The space on which humans interact with machines. The remote control of your television, the button pad on your washing machine, the speedometer on your motorbike, the elevator panel — all of them are user interfaces. UI is the most visible and arguably the important part of human-machine interaction. It has one job: To enable users to effectively operate and control machines.
If you went to school in the 90s, you’d have been taught input devices and output devices like keyboard and printer. User interface includes both. It is the input end, where users give commands and the output end where the machine gives the user information that helps them move forward in the interaction. But most machines today have input and output devices combined — for instance, your mobile phone screen can accept input from you and display/speak output.
What is UI Design?
User interface design is the process of building interfaces for machines. While it is typically for computers and mobile phones, large-scale digitization and intelligent devices have expanded the scope of UI design to include smart TVs, refrigerators, automobiles, etc.
Evolution of User Interface

The invention of the user interface dates back to the invention of computers itself. It started with the punch card: On which holes were punched at strategic gaps to represent data. This was then fed into the computer which had a card-reader, which translated the holes into digital information. A few years later, the punch cards were slowly replaced by magnetic tapes. While these media were used for input, the output was often printed by a printer connected to the computing device.
Command-line interfaces soon came into use, reducing latency, and enabling users to code faster.
Then came the graphical user interface (GUI), which is still the most prevalent form of UI. From laptops and television to mobile phones and gaming consoles, GUI dominates the way users interact with devices. Also in this journey are menu-driven interfaces, like in an ATM machine and form-based interfaces, such as an online job application.
Kinds of UI
A human can interact with machines in all the ways they can sense interactions — visual (sight), auditory (sound), tactile (touch), olfactory (smell) and gustatory (taste).
- At the most relatable end, you have mobile, tablet and laptop devices that you can see and touch.
- Notification on mobiles or the ding of the slot machine are long-time examples of sound as UI. With voice-activated assistants like Siri and Cortana gaining popularity, sound-based interactions with machines will only grow.
- You might think smell and taste as UI aren’t coming anytime soon, but you’d be surprised. Researchers are exploring synthesizing olfactory sensations for augmented reality/virtual reality applications as we speak. Taste is only a matter of time.
Goals of UI Design
Like they say, good UI design is one where users don’t have to think. To achieve that goal, a UI designer needs to keep the following in mind.
Application usability: The Nielsen Norman Group, founded by usability expert Jakob Neisen and UX veteran Don Norman, lists five aspects of usability: “Learnability, efficiency, memorability, errors and satisfaction”: If a user finds your application easy to learn, quick to use, simple to remember, makes few errors and enjoys using it, voila, you’ve passed the usability test.
High discoverability: If your application makes the user jump through hoops and stand upside down to find the information they need, you have a discoverability problem. A good UI designer will ensure that the user can find the information they need in very few clicks and minimal effort.
Aesthetic appeal: For as long as computers were for geeks, aesthetic appeal was frowned upon. That no longer applies. Researchers Masaaki Kurosu and Kaori Kashimura from the Hitachi Design Center noticed as early as in 1995 that people prefer beautiful-looking products over not-so-beautiful ones, irrespective of how they perform. Good UI needs to be as much appealing as it is useful.
Branding: For each purpose today, there are dime a dozen applications. In the SaaS economy, the cost of users switching applications is extremely low. UI must establish brand recognition for the product and facilitate brand recall.
The UI Design Process
- Requirement gathering
- User behaviour research
- User journey mapping
- Layout design and prototyping
- Design including colours, shapes, typography etc.
- Testing
Role of UI Design in UX
User interface design is about building the space where the interaction between a human and a machine happens. User experience (UX) design is everything that encompasses a customer’s interaction with a product.
So, UX = UI + application logic.
This doesn’t make one better or more important than the other. The user interface design heavily influences user experience. It shapes how the user finds information, how well they understand the product, how easily navigate to perform the tasks they want to perform, how consistently they experience the product across devices etc.
UI and UX are complementary areas, going hand in hand across application design. Most often a UI designer and a UX designer will work closely, offering feedback and collaborating on each other’s work. Some UI design tools are also used by UX designers. You’ll see most technology companies advertising for roles combining UI and UX skills such as ‘UI/UX designer’ — not because they don’t know the difference, but because they are often inseparable. This is also why Springboard’s online learning program is structured as UI/UX design that comes with 1:1 mentoring, project-based curriculum and career coaching— where you learn ‘design’ as a whole, instead of just 1-2 aspects.

One of the nice new features that came out with iOS 14 were some new options around the venerable UIDatePicker. There are now some choices other than just the slot machine-style wheels! Since iOS 2.0, the original style of UIDatePicker has been the only standard UIKit option for developers looking to let users select dates and times. The UIDatePicker got a little bit of a facelift with the new styles in iOS 7+ but really hasn’t had much love since then. With iOS 13.4 and iOS 14.0, things changed with the addition of the UIDatePickerStyle enumeration and the addition of two new styles other than the default wheels.
Setting UIDatePicker Style
The new UIDatePickerStyle enum has four options:
wheels– Shows the standard, spinning wheel style picker. (iOS 13.4+)compact– Displays a formatted label that will show a popover with more UI when tapped. (iOS 13.4+)inline– An editable field meant to be used inline. (iOS 14.0+)automatic– Will pick the most appropriate style based on the mode and platform. Usually on iOS this will wind up beingwheelsbut Mac Catalyst apps might usecompactor another style. (iOS 13.4+)
While you certainly could let the UIDatePicker select the style for you with automatic, I’d suggest manually setting the style to your preferred option to avoid unexpected UI changes with future iOS releases. Also there is no guarantee that the current default for datePickerStyle of wheels will stay that way forever.
Setting the date picker style is as simple as changing the preferredDatePickerStyle property on the date picker instance that you are using.
The above code will result in the nice new inline interface. Unfortunately the inline style takes up quite a bit of vertical space, but it does let you avoid additional UI transitions, popovers, etc. if that’s what you need.
If you want to use the compact style, it’s just a different value for preferredDatePickerStyle.
The compact style will initially present UI that looks like this.
When the user taps on the date or the time in this case, the entire calendar and time control combination appears in a popover window.
You’ll notice of course when you use it that this looks and behaves exactly like the inline date picker style but is presented in a modal window with a translucent background.
Date and Time Only Options
The UI above all shows examples of date and time but of course you can (and most of the time) probably will just display one or the other. The Date and Time only inline styles are basically just cropped versions of the full UI.
The compact UI collapsed mode with just the date and times fit quite nicely into an existing UI with rounded text fields and definitely provide the most space-efficient option. This style also has the advantage of removing that extra label or button control that developers have had to use to trigger the existing UIDatePicker UI in the past.
Don’t Forget About Locale
One of the major benefits of using the Apple-provided UIDatePicker instead of trying to spin your own is out-of-the-box internationalization. By just setting the locale property on the date picker to “zh_CN” for example, we can get a Chinese language date time picker. Cool, huh?
Not Available for Countdown Timer Mode
Note that none of these new styles are available if your datePickerMode is set to countdownTimer. As of iOS 14.2, setting a countdown timer date picker to compact or inline will actually cause a run-time app crash (I’ve submitted feedback to Apple on this so hopefully it will get resolved down the road).
Which Style Do I Pick?
Which user interface for the UIDatePicker that you prefer is obviously up to you as an app developer. It is always most important to consider your users, what they expect as iOS users, and what will make their experience in your app the most delightful. The new UIDatePicker options will at least let us refresh our apps and keep them up to date going forward. Apple provides some guidance in the Human Interface Guidelines (HIG) but not a ton. As always, while new UI provides us with some choices (and some compromises), which way to go on your app’s journey is up to you.
