# objc_dupclass

Tired of this warning?

```

objc[65171]: Class CDPCAReporter is implemented in both A.framework and B.framework.

One of the two will be used. Which one is undefined.

```

Luckily, as I discovered from [this

tweet](https://twitter.com/_saagarjha/status/1509140471104241665), Apple

[added](https://github.com/apple-oss-distributions/objc4/commit/62b60ba0e56440e265ca576cc9f197e9af54c1bd#diff-510a2060e3422b44e197951716a1f6bb257728a9c61efd7ae0f8c16364212f89R174)

a special way to silence these warnings for classes you specify. This

repo provides a C macro for adding classes to this special list.

## Usage

Call the macro in any Objective-C / C / C++ file in your project,

passing the class you want to silence the warning for:

```c

#include "objc_dupclass.h"

OBJC_DUPCLASS(AMSupportURLConnectionDelegate);

```
