How to assign a completion handler to another in Objective-C

I have an issue in Completion handler.

I have a method as below 

-(void)authenticationRealmWithCompletion:(void (^)(AuthenticationRealm *authenticationRealm, NSError *error))completion realmId:(NSString *)realmId postDictionary:(NSDictionary *)postDictionary{
//my code
    }

Now I declared a variable as below 

typedef void(^completionHandler)(AuthenticationRealm *authenticationRealm, NSError *error);

Now I want to assign as below

-(void)authenticationRealmWithCompletion:(void (^)(AuthenticationRealm *authenticationRealm, NSError *error))completion realmId:(NSString *)realmId postDictionary:(NSDictionary *)postDictionary{
[completion copy];

//**HERE**..... Error Line
completionHandler(completion);   

//my code



 }

But I am getting error as Redefinition of 'completion'

Please suggest how to assign completion handler to another.

To assign completion handler you have to create property of completion handler.

@property (nonatomic, copy) completionHandler completion;

Then in your method assign using below code.

self.completion = completion;

Update

Method also be define as 

-(void)authenticationRealmWithCompletion:(completionHandler)completion
                             realmId:(NSString *)realmId
                      postDictionary:(NSDictionary *)postDictionary{

self.completion = completion;

}
