What examples of automatic code generation templates are you familiar with?

Automatic code generation templates help speed up development and reduce errors. In iOS development, the following examples are often used:

• Code Snippets — ready-made code templates in Xcode that can be quickly inserted.
• SwiftUI Previews — automatic interface generation based on code.
• Core Data Model Code Generation — Xcode can automatically create NSManagedObject classes from a data model.
• Sourcery — a tool for generating repetitive Swift code using templates.
• Protocol-Oriented Programming Templates — generating boilerplate code for protocols and extensions.

Example of using Sourcery to generate code:

// sourcery: AutoMockable
protocol NetworkService {
    func fetchData()
}

Sourcery will generate a mock implementation for testing, saving time.
