TextKit storage layers can be difficult to design and debug. This guide clarifies the architecture and lifecycle of NSTextStorage, NSTextContentStorage, and NSTextContentManager, including how they interact and how to reason about backing stores.
Start by reviewing the storage architecture and implement a minimal NSTextStorage subclass with proper edited calls.

To subclass NSTextStorage for a custom backing store, implement the editing lifecycle by calling beginEditing, edited:range:changeInLength:, and processEditing to ensure safe mutation reporting and maintain string and attribute consistency.
NSTextContentStorage bridges to NSTextContentManager by generating paragraph elements and synchronizing content across storage and content manager interfaces, ensuring consistent regeneration of the element tree during text updates.
The NSTextStorage editing lifecycle requires batching edits within beginEditing and processEditing calls, maintaining correct changeInLength values to avoid common pitfalls and ensure thread-safe text storage mutations.
Implementing TextKit 2 storage with a CRDT backend requires subclassing NSTextContentStorage and related delegates, applying transaction patterns to ensure safe mutation reporting and consistent element tree regeneration across interfaces.
Incorrect changeInLength during NSTextStorage batching usually stems from mismatched length deltas between the edited range and the backing store, causing inconsistent attribute state; apply proper transaction patterns to resolve this.
