Opus 4.8: Native macOS App for Improving Writing

Amos Gyamfi

Animation & Coding: AI, Python, Swift, SwiftUI

New AI model, new app. This tutorial uses Claude Opus 4.8 (just released) to create a native macOS writing tool.

What the app does:

Accepts text input from the user
Sends it to Opus 4.8 via API
Returns writing improvements, style suggestions, and summaries
Runs as a proper native macOS SwiftUI app

What you'll see:

Integrating Opus 4.8 API into a Mac app
Handling streaming responses
Building a clean writing-focused UI
Source code available to download and modify

Perfect for macOS developers who want to ship AI-powered tools without building from scratch.

Fastlane alternative – CLI tools

Are you tired of Ruby and Fastlane installation issues? There's got to be a better way! Discover Codemagic open source CLI tools. It is not a drop-in replacement for all of what Fastlane does (screenshots for example), but we use it at Codemagic to build and publish iOS and Android apps, also versioning and device provisioning.
