This method(SecRandomCopyBytes) is wrong in Xcode 9 Beta

[SpringAndSummer]

extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, uint8_t *bytes) attribute((weak_import));

I meet the same thing.

[nserror]

also seeing the same issue

[aizliang]

me too

The iOS 11 SDK has changed the last parameter of its declaration of SecRandomCopyBytes from uint8_t * to void *, so the declarations no-longer match.

A workaround for this is to replace the line

extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, uint8_t *bytes) __attribute__((weak_import));

with

extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, void *bytes) __attribute__((weak_import));

or, if you need to support building with previous SDKs too, with

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 110000
extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, void *bytes) __attribute__((weak_import));
#else
extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, uint8_t *bytes) __attribute__((weak_import));
#endif

Could this be fixed?

Nice! Rob is on it!

PS: Nice talk at UIKonf once again!

Can anyone confirm that they're seeing this in the Swift version (this repository currently holds the Swift version, not the ObjC version; that got moved over to RNCryptor-objc).

[rnapier]

Note that this is resolved in the ObjC version; please let me know if anyone is having trouble in the Swift version (I don't think you should be).

@rnapier I am using pod 'RNCryptor-objc', '~> 3.0' and still i am getting errro at

Can you please suggets how can i resolve this issue .
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 110000
extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, void *bytes) attribute((weak_import));
#else
extern int SecRandomCopyBytes(SecRandomRef rnd, size_t count, uint8_t *bytes) attribute((weak_import));
#endif

Thanks,

The pod version should be 3.0.5:

Am I misreading something? (I don't use CocoaPods myself, so this doesn't come up in any of my projects.)
