Repository System for Advanced App Customization

Scarlet iOS enables users to expand their app library through custom repository sources, allowing access to specialized applications beyond standard channels.

The platform supports JSON format repository creation, giving advanced users the ability to structure and organize their own app collections with specific metadata, version information, and download links. Bundle Identifiers and App Store ID are automatically populated when adding applications to maintain proper app tracking and distribution management.

Users can modify IPA files with tweaks directly through the repository system, injecting custom code or features into applications before installation for enhanced functionality and personalization. The system maintains AltStore repository compatibility, ensuring seamless integration with existing alternative app distribution platforms.

Adding Custom Repository Sources

Developers can expand iOS app capabilities by integrating custom repository sources, which provide controlled access to proprietary frameworks, internal libraries, and specialized third-party components.

CocoaPods enables registration of private spec repositories through `pod repo add` commands, while Swift Package Manager supports direct URL-based package additions via Xcode. Both systems enforce version control, authentication, and granular dependency management. Organizations can maintain internal pod repositories for centralized management of proprietary code and controlled distribution across development teams. Before deployment, developers should utilize validation commands to check podspec files against CocoaPods specs guidelines and identify potential issues.

Key Integration Methods:

• Register CocoaPods repositories using Git URLs from GitHub, GitLab, or Bitbucket
• Add Swift packages through Xcode’s File menu with repository authentication
• Reference custom sources in Podfiles using `source` declarations
• Pin dependencies to specific branches, tags, or commits for stability

JSON Format Repository Creation

Advanced app customization relies on structured JSON configuration files that define build behaviors, metadata, and platform-specific settings within repository systems.

Root-level files like app.json specify essential fields: appId, root, iosPath, androidPath, ensuring accurate project location mapping. Include display name, slug, sdkVersion, version control data for complete metadata coverage.

Define ios.buildNumber, ios.version, ios.runtimeVersion.policy for platform-specific builds. Set dependencyInstallCommand and webBuildCommand fields to automate installation and build processes. The repository permits multiple apps in subfolders, each defined within the apps array with distinct configurations.

Validate JSON structure using editor tools, which provide real-time syntax checking, schema preview, and error highlighting. Maintain one main config file at repository root for streamlined version control, CI/CD automation. Configure the 6-character hex string to set the background color property that defines the root view appearance across the application.

Modifying IPAS With Tweaks

• Dynamic library injection via hooking frameworks and substrates
• Entitlements editing to expand app permissions and capabilities
• CodeResources recalculation for signature hash compatibility
• Filesystem patching for persistent behavioral changes

Repository automation streamlines distribution of pre-modified IPAs, organized by version and tweak type.

Local and remote sources support testing, rollback, and staged deployment across managed device fleets.

Integration with major Git-based source control providers enables version tracking and collaborative management of tweak repositories across development teams.Push notifications deliver real-time alerts when modified IPAs receive updates or require attention.
