• Do your iOS team have the same things in place? • What was the hardest thing to achieve while implementing your design system? • Do you plan to move your code to Jetpack Compose? If so, how? • Are there any limitation to this system? • Why are you using a grid system? What are the advantages? QUESTIONS ⁉
