With WWDC 2021 just around the corner I've been thinking about what I'd like to see there.

A lot of the popular discourse around this time of year is focussed on features of the operating systems but I want to look at what I'd like to see as a developer for Apple platforms.

Running UI Tests on Mac Catalyst


While working on the 2.0 update for Gathered I have been trying to develop the app multiple platforms simultaneously. SwiftUI will solve this problem in the future, but I wish to support some OS versions that SwiftUI does not support.

Touch ID on the Lock Screen


Touch ID is a wonderful piece of technology, to the point where wouldn't buy an iOS device without it. It had many great uses, such as:

  • Authorise Apple Pay payments
  • Add biometric restrictions within apps

However, I wish to discuss the first of these: unlocking the device.
