The app references non-public selectors in Payload/<Appname>.app/<App name>: decoder

Question

I am getting this warning while submitting app to the Apps store through organizer.

The app references non-public selectors in Payload/.app/: decoder

i know we get this warning if we use any Third Party API in our application. I have used SOCKETIO-ObjC library for chat functionality in application. Also used facebook iOS sdk for fb implementation.So i am not getting exactly what causes this warning.! Please find attached ScreenShot for better understanding

Solution 1

You may get this warning just for using a selector in your own code or third party code that has the same name as some selector that is marked as non-public. Happens to me all the time. Never got rejected for it.

By "same name" i mean just something as simple as you having an object with this selector:

-(id) XYZKMyClass doSomethingFancy:(id) toThis

...and there being a selector like this for an internal Apple functionality

-(id) ApplesClass  doSomethingFancy:(id) toSomething

So: What it seems they are looking for is the signature -(id) doSomethingFancy:(id). You can see how it's very easy to accidentally bump up against this.

Presumably they perform a deeper check at the App Store Police HQ, and determine that the flagged selector is in your code, and hence OK.

This can help you:

Before:

#import "SocketIOJSONSerialization.h"

extern NSString * const SocketIOException;

// covers the methods in SBJson and JSONKit
@interface NSObject (SocketIOJSONSerialization)

// used by both JSONKit and SBJson
- (id) objectWithData:(NSData *)data;

// Use by JSONKit serialization
- (NSString *) JSONString;
**- (id) decoder;**

// Used by SBJsonWriter
- (NSString *) stringWithObject:(id)object;

@end

After:

#import "SocketIOJSONSerialization.h"

extern NSString * const SocketIOException;

// covers the methods in SBJson and JSONKit
@interface NSObject (SocketIOJSONSerialization)

// used by both JSONKit and SBJson
- (id) objectWithData:(NSData *)data;

// Use by JSONKit serialization
- (NSString *) JSONString;
**- (id) jsonDecoder;**

// Used by SBJsonWriter
- (NSString *) stringWithObject:(id)object;

@end

Check your Target Membership for all classes used in project. In some cases when you create or copy your target the warning may appears without link error.

You're welcome. Sorry I can't get you a link to an official explanation, but I haven't been able to find any on this topic. All I can say for sure is that this happens to me every time I submit an update to my primary app, and nothing bad has happened so far.

I wish there was a way to search for the non-public selector so that I could rename it.

Aware that this thread is months old but ... Is there way to be informed of the namespace collision at compile/build time rather than after submitting the app to the store?

[Anders Johansen]

Hi Byron, sorry if there is I have not found it.

[Dhaval Bhadania]

can apple will reject for same warning like : The app references non-public selectors in Payload/.app/: id @AndersJohansen

[Anders Johansen]

What do you mean Dhaval?

[Hackmodford]

@DhavalBhadania I have not been rejected and have submitted updates multiple times.

[Shaheen Ghiassy]

That was my exact problem. Thanks

I was just so lazy I didn't see that it didn't stop the app to upload to iTunes Connect. Thanks, mate.

Any idea for searching such public selector ?
