WWDC20: 6 Latest Additions in SwiftUI for iOS Developers

In the world of product design, consistency is the cornerstone of delivering a seamless user experience. As digital products evolve and scale, the challenge of maintaining design consistency across multiple platforms, teams, and touchpoints becomes more complex. This is where design systems come in. A design system is a comprehensive set of guidelines, components, and tools that help designers and developers create a consistent and cohesive user interface (UI) and user experience (UX). From a designer’s perspective, building and maintaining a design system requires a strategic approach to ensure scalability, flexibility, and alignment with business goals.

Why Design Systems Matter?

Design systems are more than just style guides or pattern libraries. They offer a unified language for design and development, bridging the gap between creativity and functionality. Here are a few reasons why they are critical:

1. Consistency Across Products

      One of the primary goals of a design system is to ensure uniformity across different platforms and devices. When users interact with a product, whether on a website or a mobile app, they expect a consistent experience. A well-implemented design system ensures that visual elements, interactions, and behaviors are aligned, offering a familiar and intuitive experience for users.

2. Faster Iteration

      With a design system in place, teams can reuse components and patterns rather than reinventing the wheel for each new feature. This speeds up the design and development process, allowing teams to focus on solving new problems instead of reworking existing designs. For designers, it means less time spent on repetitive tasks and more time dedicated to innovation.

3. Scalability

     As products grow and new features are added, maintaining a coherent UI/UX without a design system can become chaotic. A design system provides a scalable framework, enabling teams to add new elements or modules without compromising the overall consistency of the product.

4. Improved Collaboration

      A design system fosters collaboration between designers, developers, and other stakeholders by providing a shared language and reference point. This ensures that design decisions are communicated effectively, reducing friction and misunderstandings between teams.

Building a Design System: A Designer’s Perspective

Designing a system from scratch can seem like a daunting task, but with a clear roadmap and understanding of core principles, it becomes a powerful tool for creating scalable and user-centered products.

1. Define the Core Principles

Before diving into visual components, it’s essential to establish the core principles of your design system. These principles serve as the foundation and guide decision-making throughout the process. Ask yourself:

• What are the key values of your brand?

• How should the design reflect the needs and emotions of users?

• What goals are you trying to achieve with your design system (e.g., accessibility, flexibility, innovation)?

   For instance, if accessibility is a top priority, you’ll need to ensure that your design system accommodates users with different abilities, by providing color contrast guidelines, clear typographic hierarchies, and accessible components.

2. Create a Unified Visual Language

Once the principles are established, the next step is creating a cohesive visual language. This includes defining elements such as:

• Color Palette: A well-structured color palette ensures harmony across different UI components. It’s crucial to include primary, secondary, and accent colors, along with usage guidelines to avoid inconsistency.

• Typography: Define a typography system that establishes hierarchies and clarity, including font styles, sizes, line heights, and spacing. Consistent typography helps users navigate content effortlessly.

• Spacing and Grids: An established grid system ensures a balanced layout and harmony between different UI elements. Proper spacing guidelines prevent crowded or misaligned components.

• Iconography and Illustrations: Design guidelines for icons and illustrations help maintain visual consistency. Icons should follow a standard style (outlined, filled) and size, ensuring they align with the overall visual language.

3. Design Reusable Components

A design system is incomplete without reusable UI components. These components include buttons, forms, modals, and navigation elements that can be used across various features and pages. Each component should be:

• Modular: Components should be flexible and adaptable for different contexts. For example, a button should have variations for different states (hover, active, disabled) and types (primary, secondary, destructive).

• Documented: Each component needs comprehensive documentation that explains how it should be used, its variants, and the rules governing its application. This ensures consistency when different team members use the same component.

4. Implement Accessibility Guidelines

Accessibility should be at the forefront of every design system. As a designer, consider:

• Color Contrast: Ensure sufficient contrast between text and background for readability.

• Keyboard Navigation: Ensure that interactive components are navigable via keyboard for users who rely on keyboard shortcuts.

• Responsive Design: Components should be responsive, adapting seamlessly across different screen sizes and devices.

• Assistive Technologies: Design components should be compatible with screen readers and other assistive technologies to provide an inclusive experience.

Maintaining a Design System: Evolving with the Product

Once a design system is in place, the work doesn’t stop there. Maintaining it requires ongoing effort as the product evolves and new design challenges emerge. Here’s how designers can ensure the design system remains relevant and effective:

1. Regular Audits and Updates

A design system should be treated as a living document that evolves with the product. Regular audits are necessary to identify outdated or unused components. Designers should collaborate with developers to ensure new features are aligned with the existing design system, and updates should be documented to avoid fragmentation.

2. Version Control and Documentation

Version control is essential for keeping track of changes in the design system. Documenting why and how changes are made ensures that the design system grows in an organized manner. It also helps onboard new team members quickly, as they can reference updated guidelines.

3. Foster Collaboration Across Teams

Designers need to maintain an open line of communication with developers and other teams using the design system. Tools like Figma, Sketch, and Zeplin allow designers to share components and guidelines in real-time, fostering collaboration and ensuring that everyone is aligned.

Some well-known examples of design systems that have set benchmarks in the industry:

1. Google Material Design
