Core Data and SwiftData are powerful data management frameworks designed by Apple for developers, capable of efficiently handling complex object relationships, hence known as object graph management frameworks. In these two frameworks, NSManagedObjectID and PersistentIdentifier serve similar functions and are both extremely important. This article will delve into their features, usage methods, and important considerations.

Data binning is a commonly used data processing technique that typically divides continuous numerical or temporal data into multiple intervals (which are mostly adjacent and non-overlapping). This method not only covers the entire data range but also provides clear demarcation for data points within each interval. By performing data binning, we can analyze, visualize, and statistically process complex datasets more effectively. This article will explore how to use the advanced APIs provided by Swift Charts to achieve precise and efficient data binning.

Compared to Core Data, SwiftData has fundamentally revolutionized the way data models are constructed. It not only supports a purely code-based declaration method but also allows the direct use of types conforming to the Codable protocol and enum types within models, which are its significant new features. Many developers are inclined to leverage these new capabilities because they seem to fit very well with the Swift language’s declaration style. However, a lack of understanding of the implementation details and potential limitations of these new features may lead to various issues in the future. This article aims to discuss several key points to consider when using Codable and enums in SwiftData models, helping developers avoid common pitfalls.
