InterposeKit is a modern Swift library for method swizzling that hooks @objc dynamic Swift functions and Objective-C instance methods on classes or individual objects. It replaces implementations directly via class_replaceMethod instead of method_exchangeImplementations, avoiding common swizzling pitfalls.

Use cases

• swizzle an Objective-C method in Swift
• hook a method to run code before or after the original implementation
• patch a framework method at runtime to work around a bug
• interpose on a single object instance instead of the whole class
• replace method_exchangeImplementations-based swizzling with a safer approach

When to choose

• you need elegant, type-safe method swizzling in pure Swift
• you want to hook @objc dynamic methods or Objective-C instance methods
• you need per-instance hooks or before/instead/after semantics like the Aspects library

When to avoid

• you need dynamic subclassing, which InterposeKit does not implement
• your methods are not exposed to the Objective-C runtime
• you want an actively maintained library - the repository was archived in June 2026 and is read-only
