SwiftUI Is Convenient, but Slow
I've been sitting on publishing these notes for a while, because I don't want to diminish the work of the talented people that engineered SwiftUI and plowed through years of AppKit and UIKit code to get to this state.

Use fast data algorithms (2021)
As an engineer who primarily works with data and databases I spend a lot of time moving data around, hashing it, compressing it, decompressing it and generally trying to shovel it between VMs and blob stores over TLS. I am constantly surprised by how many systems only support slow, inefficient, and expensive ways of…
