## AI overview

This tutorial explains Swift result builders and declarative programming, then applies custom result builders to encoding binary-formatted data. It also introduces DataKit, a Swift library for declaratively specifying binary message formats for encoding and decoding.

## Source excerpt

SwiftUI has revolutionized how we build UI, introducing a more intuitive, declarative approach. Instead of prescribing a series of steps to reach an end goal, we describe the outcome and let the program determine the path The post Swift Result Builders: Creating Custom DSLs for Binary Formatted Data appeared first on QuickBird Studios.
