iOS Dev Tools: ch.at, Mercato, Dependencies
The best tools at your fingertips.
Hey developer! 👋
Yesterday I’ve launched a new newsletter - Indie App Devs
Each week we will have a different topic to help Indie app developers improve ASO, design elements, tips, ideas, and business.
This week we start with Teodora owner of Designerants and App Growth Academy. Her screenshots convert to downloads and revenue on the App Store.
Read here ➡️ 5 screenshot hacks developers to get more downloads.
Thank you for your support!
If you have a tool that solves a developer problem, I would love to help you reach iOS developers - hi@iosdev.tools
Forget about Ruby and Fastlane installation issues!
Discover Codemagic CLI tools — the free, open-source Fastlane alternative for automating iOS builds, code signing and publishing.
ch.at
A minimal, privacy-focused chat interface to large language models, available via web, terminal, DNS, and API—no JavaScript, no accounts, no tracking. Ships as a single static Go binary for fast, flexible deployment anywhere.
Why you will like it:
Multi-Protocol Access: Use over HTTP, SSH, DNS, or OpenAI-compatible API.
Lightweight Design: ~1,300 lines of Go, three dependencies, single static binary.
Privacy by Default: No authentication, logging, or server-side storage.
Easy Deployment: Runs on bare metal, Docker, or as a nanos unikernel.
Web Without JavaScript: Fully functional browser interface with zero client tracking.
Mercato
A lightweight Swift package that wraps StoreKit 2, making in-app purchases, subscriptions, and transaction management easier to implement and maintain.
Why you will like it:
Transaction Monitoring: Built-in streams for current entitlements and live updates.
Subscription Tools: Intro offer checks, trial detection, and price breakdowns.
Flexible Purchase Options: Configure quantity, promotional offers, and account tokens.
Utility Helpers: Quick purchase status checks, latest transaction retrieval, and syncing.
Dependencies
A structured approach to controlling and propagating dependencies in Swift, enabling fast, deterministic tests, seamless SwiftUI previews, and safer code.
It solves common pitfalls of uncontrolled dependencies while making overrides and testing more ergonomic.
Why you will like it:
Full Dependency Control: Abstracts away network, file, clock, and other external systems.
Ergonomic Propagation: Share dependencies across your app without unsafe global state.
Scoped Overrides: Replace dependencies for tests, previews, or specific feature flows.
Override Verification: Ensures all external interactions in tests are mocked.
Preview & Simulator Support: Works smoothly with SwiftUI previews and simulator environments.
Snippetbar
Run custom AI prompts on any copied text — right from your Mac’s menu bar.
Habits
Mac's menu bar and helps you keep track of your daily habits.
This is a paid app ($20), but with the code REDDIT you can get it for free!
