Answer 4

There is no predefined template to create category in Xcode 6 beta(for time being),they may add this option later. As a work around you can create a Cocoa Touch Class(its not proper i know but no other way) named UIImage+Additions(ClassName+CategoryName) and override its interface and implementation some thing like

UIImage+Additions.h

#import <UIKit/UIKit.h>

@interface UIImage(Additions)

+(void)testMethod;

@end 

UIImage+Additions.m

#import "UIImage+Additions.h"

@implementation UIImage (Additions)

+(void)testMethod
{

}

@end

PS. Under File Name: whatever you type here will be either the Category, Protocol, or Extension Name.
