It's Not That the Models Are Slower—The Tasks Have Become Bigger -- Fatbobman's Swift Weekly #146

A Swift-focused weekly newsletter covering the shift in AI-assisted development workflows where tasks have grown larger and more complex. Technical highlights include using Swift 6.2 Custom Executor to bridge CoreBluetooth delegates with Actor isolation, practical Xcode CLI techniques for CI environments, GitHub Actions cost optimization strategies, building adaptive SwiftUI panels for resizable environments, the new @ContentBuilder type alias in Xcode 27, and tswift — a lightweight Swift runtime implemented in Rust that can parse and execute Swift without the official toolchain.
