wtf is shmdatabase?

SHMDatabase is a tool that helps iOS app developers save and manage data on the device itself, rather than relying entirely on a remote server. It acts as a bridge between an app and its local storage, allowing developers to quickly set up a database without getting bogged down in the underlying technical details. In everyday terms, it lets developers take a piece of information, like a user's profile or a saved document, and easily store it, find it later, update it, or delete it. The framework automatically handles the messy plumbing: it creates the database tables, assigns unique ID numbers to each entry, and tracks when an item was created or updated. Developers simply interact with their normal data objects, and the framework translates those actions into the database commands needed to save them. This tool is built for iOS developers who want a fast, lightweight way to handle local data. For example, a team building a note-taking app like the one this framework was originally built for could use it to save drafts offline. When a user creates or edits a note, the app calls a simple save command. The framework handles storing that note securely on the phone, and if the developer later needs to add a new "tags" field to their notes, they can upgrade the database with a single line of code. A notable design choice is that it requires no special base classes, meaning developers can attach it to existing code without forcing a major rewrite. It also handles complex data easily, like storing arrays or images, and ensures that batch operations either fully succeed or roll back safely if something goes wrong. This makes it a practical choice for developers who want reliable local storage without writing tedious, repetitive database code.
