In my weekly office hours at lululemon, I help provide feedback to designers on best practices for iOS design, but also through the lens of a growing design system.

Here are some of the common questions I’m thinking about when trying to provide actionable feedback.

General

• Will any parts of this design be confusing to the end user?

• Does it introduce any elements that go against what Apple typically recommends? If so, how is it justified?

• Has it been tested on device using a prototype?

• Are essential elements easily reachable?

• Has it been discussed at an early stage with a developer to determine if any APIs or unknown states should be considered?

• Have the most common states been considered? Ideal state, empty state, loading state, error state.

Layout

• Does this design adhere to our standardized spacing rules in the system?

• Does the spacing reflect a proper sense of hierarchy?

• Does the layout still work, ranging from an iPhone Mini to a Max?

• If there are input fields, what considerations to the design have been made when a keyboard slides into view?

• If the content is scrollable, are there affordances indicating it is?

• What are the navigation patterns around entering or exiting this view? Does it slide in? push? slide up?

• Does the design include real production data?

• Are all safe areas properly visible?

Style

• Are call to actions being used to clearly indicate what the primary, secondary, and tertiary actions are on the screen?

• Are there new components being used where existing components will do?

• Are icons easy to understand?

• Are brand guidelines being followed when it comes to grammar, punctuation, tone, and spelling?

• Do animations feel out of place?

• Would animations help the overall design?

• Can any unnecessary elements be removed?

Interaction

• Are there any haptics to consider?

• Is it clear what’s interactive and what is not?

• Are touch targets large enough for interactive elements?

• Does a loading indicator need to appear while data is being fetched?

• Do interactive items provide feedback when touched?

Accessiblity

• Does the layout break if the user increases their dynamic type settings?

• Have new layout considerations been thought through if we need to support extra large type settings?

• Has VoiceOver been considered?

• Are color contrast guidelines being met?
