Its core idea is the two-class pattern for each Core Data entity: a generated machine-owned class such as _MyEntity that can be overwritten to match the model, and a human-owned subclass such as MyEntity where app-specific logic lives. That split made it attractive to Objective-C Mac and iOS developers who wanted generated accessors and constants without losing hand-written business logic every time the model changed. ### Project history The project became a notable tool in the Cocoa/Core Data ecosystem. Its README describes the command-line workflow around .xcdatamodel files, and a 2012 Edge Cases episode presented it as a popular open source Core Data code generation tool. In practice, developers ran mogenerator manually, from scripts, or from Xcode build phases to keep generated Objective-C classes synchronized with a Core Data model. ### Adoption history Major milestones tracked in the project's version history include the 2014 v1.28 release adding a --v2 argument for modern defaults and experimental Swift code generation, v1.29 adding a built-in model compiler instead of relying on Xcode's momc, v1.30 making modern Objective-C and Swift defaults while adding bundled Swift 2 templates, and v1.31 adding Swift 3 support. Later releases added support for newer Core Data property types, nullability annotations, Swift fetchRequest generation, and more template metadata. ### How it is used Its package-manager niche is narrow but durable: a macOS developer CLI for legacy and long-lived Core Data projects, adjacent to Xcode's own model tooling but more opinionated about generated code ownership. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mogenerator - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Requirements:** macos, xcode - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - MacPorts - mogenerator: normalized package name match | MacPorts ports tree: devel/mogenerator/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [configen](https://www.automicvault.com/pkg/brew/configen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, objective-c, swift. - [create-api](https://www.automicvault.com/pkg/brew/create-api/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, swift. - [mockolo](https://www.automicvault.com/pkg/brew/mockolo/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, swift. - [objc-codegenutils](https://www.automicvault.com/pkg/brew/objc-codegenutils/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, objective-c. - [plank](https://www.automicvault.com/pkg/brew/plank/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, objective-c. - [rswift](https://www.automicvault.com/pkg/brew/rswift/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, swift. - [sourcery](https://www.automicvault.com/pkg/brew/sourcery/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, swift. - [swiftgen](https://www.automicvault.com/pkg/brew/swiftgen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, swift. ## Combined YAML source View the package source record on GitHub.
