This repository implements a comprehensive, production-grade CLI tool (`asc`) for interacting with Apple's App Store Connect API, Apple Ads API, and Apple Developer Portal. It automates the entire lifecycle of Apple platform applications, including authentication, app and build management, versioning, localization, screenshots, pricing, subscriptions, in-app purchases, Game Center features, code signing, distribution, and publishing. The tool is designed for CI/CD integration and supports multiple output formats (JSON, table, markdown) with a rich set of validation and diagnostic capabilities. The architecture is a monolithic CLI application built on a custom Go-like language with a sophisticated build system (`go.mod`, `go.sum`, `//go:build` directives). It follows a clean layered architecture: a command layer using the `ffcli` library, a comprehensive API client layer (`internal/asc/`), a secure authentication layer (`internal/auth/`), and platform-specific implementations for file operations, process management, and security. The codebase is exceptionally well-tested with thousands of unit and integration tests, including platform-specific tests for Darwin, Linux, and Windows. Notable engineering highlights include a generic pagination system with cycle detection, a registry-based output rendering system, a robust validation framework with structured remediation, and cross-platform secure file operations that prevent symlink attacks using platform-specific syscalls. The project also features an embedded workflow engine, telemetry with environment detection, and agent skill definitions for AI-assisted development workflows. The project is actively maintained with a structured release process, low issue count, and active dependency management. Technical drift is managed through explicit deprecation handling and migration paths. Primary risks include reliance on a custom Go toolchain, platform-specific assembly code for macOS security operations, and web session scraping that is inherently fragile to Apple Developer Portal changes.
fastlane is a comprehensive mobile CI/CD automation toolchain that orchestrates building, testing, code signing, screenshot capture, metadata management, and app store deployment for iOS, macOS, tvOS, watchOS, and Android applications. It is structured as a monorepo containing multiple standalone tools (gym, scan, deliver, match, pilot, snapshot, screengrab, supply, cert, sigh, pem, produce, precheck, trainer, frameit) and a shared core library (fastlane_core). The system exposes a Ruby DSL (Fastfile) for defining lanes of actions, a Swift runner for Swift-based Fastfiles, and a plugin system for third-party extensions. Key entry points include the `fastlane` CLI, per-tool commands (e.g., `gym`, `scan`), and the `Fastlane::Runner` that executes lane definitions. Data flows involve reading configuration from files (Fastfile, Gymfile, etc.), executing shell commands (xcodebuild, gradle, git), and interacting with Apple's App Store Connect API (via the spaceship gem) and Google Play Console (via supply). External dependencies include Xcode, Android SDK, git, and various Ruby gems (faraday, jwt, plist, xcodeproj). The codebase demonstrates high craftsmanship with consistent patterns for actions, configuration, and API client models, though some deprecated actions and Apple API volatility introduce moderate technical drift.
LiveContainer is an iOS application that acts as a runtime host for running third-party iOS apps (guest apps) without actually installing them. It leverages extensive reverse engineering of Apple's dyld, Mach-O binary format, and private iOS APIs to bypass code signing, inject tweaks (via CydiaSubstrate/ElleKit), manage multiple data containers per app, and provide multitasking (floating dock, Picture-in-Picture). The project includes a full code signing library (ZSign), a dyld validation bypass, hooking infrastructure, and integration with AltStore/SideStore for certificate import and app refreshing. The architecture is modular with separate targets for the main app, SwiftUI UI, tweak loader, signing library, process launcher, and share extension. While the code demonstrates deep iOS internals knowledge and is actively maintained, its heavy reliance on private APIs and dyld internals makes it fragile across iOS versions and limits the reusability of most components outside this specific project.
Electron Packager is a command-line tool and programmable library for packaging Electron applications into platform-specific distributables (e.g., .app, .exe, .deb). It handles Electron binary downloading, app bundling, code signing, notarization, and cross-platform builds (Windows, macOS, Linux, Mac App Store). The architecture centers around a Packager class that orchestrates the process, delegating platform-specific steps to subclasses (macOS, Win32, Linux) and utilizing utilities for dependency pruning, file filtering, ASAR creation, and hook execution. It is actively maintained with a modern TypeScript toolchain and comprehensive test suite.
