iOS Conf SG 2017 - One Blind Weekend

This talk is about the time I was temporarily blind for a weekend, and how I had to rely on Siri and VoiceOver on my phone to survive the weekend.

I share here what I experienced while “blind”, and tips on how you can improve your app accessibility for people with visual disabilities.

31. Increase legibility
32. Make sure you have good contrasts 1 ❌ “Compose tweet” ✅ “Compose tweet” Legible font sizes and weights 2 ❌ “Compose tweet” ✅ “Compose tweet” Don’t rely solely on colours to convey information 3 ℹ 1 in 12 males are colour blind ℹ Use text or shapes to provide additional context ▲▼
