A Story About Swizzling "the Right Way™" and Touch Forwarding

Read Original

The article discusses the author's experience with method swizzling in Objective-C, highlighting problems like app freezes when interacting with other SDKs. It critiques the standard use of `method_exchangeImplementations`, explains why it's flawed (e.g., breaking `_cmd` assumptions), and presents an alternative, safer implementation using blocks and careful runtime manipulation.
