It seems like your question is off-topic for the content presented at WWDC. However, I can provide some information about how Apple discusses adding personality to apps through UX writing, which might be relevant if you're looking to describe something in a unique and engaging way.

Adding Personality to Your App Through UX Writing

In the session Add personality to your app through UX writing, Apple discusses how to define and implement a distinct voice and tone for your app. Here are some key points:

1. Voice and Tone:

   • Voice: The consistent personality and style of your app's communication.
   • Tone: The emotional inflection applied to your voice, which can change depending on the context.

2. Exercises to Define Voice:

   • Think of your app as a person and list adjectives that describe its personality.
   • Group similar adjectives to identify themes.
   • Use these themes to guide your app's voice.

3. Adjusting Tone:

   • Depending on the context, adjust the balance of qualities like friendliness, simplicity, and energy.
   • For example, a welcome screen might use a more energetic and casual tone to engage users.

4. Practical Examples:

   • Apple provides examples of how to write clear, friendly, and focused text that aligns with the brand's voice.
