Odd Xcode behavior when creating classes

Question

When I go into xcode try to add a new class with File>New>New File and then adding an Objective C class, my header file winds up looking like this:

@interface Course : NSObject 

@end

instead of what it needs to look like

@interface Course : NSObject {
@private

}
@end

is there any reason for this, I'd really like to have it set up the way that the code snippet does (the second) by default.

Looks like this is normal behavior for Xcode 4.2. The new runtime does not require the creation of instance variables when you use properties.

Old runtime:

@interface Foo : NSObject
{
  NSNumber *myNumber;
}
@property (nonatomic, retain) NSNumber *myNumber;
@end;

New runtime:

@interface Foo: NSObject
@property (nonatomic, retain) NSNumber *myNumber;
@end;

This does not answer the question at all. I do not see where he is asking about instance variables or properties in his question. – chown Nov 20 '11 at 23:19
@chown The OP has asked if there’s a reason why the new templates do not have a `{@private}` block (for ivars). – Nov 20 '11 at 23:36
@Bavarious Ohhhhhhh, I get it, you'r answering the *why* part. I read his statement: "I'd really like to have it set up the (2nd) way by default" as his main question. But, this does provide an answer for the *why* part; sorry about that =). – chown Nov 20 '11 at 23:59
So the Objective C runtime changed that quickly. In the books and videos i'm using everything looks different now – bringel Nov 21 '11 at 00:38

In the

/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/Cocoa Touch/Objective-C class.xctemplate/NSObject

directory there are template files called ___FILEBASENAME___.m and ___FILEBASENAME___.h. What you need to do is change the ___FILEBASENAME___.h file (using something like vim, TextWrangler, etc) from this:

//
//  ___FILENAME___
//  ___PROJECTNAME___
//
//  Created by ___FULLUSERNAME___ on ___DATE___.
//  Copyright (c) ___YEAR___ ___ORGANIZATIONNAME___. All rights reserved.
//

___IMPORTHEADER_cocoaTouchSubclass___

@interface ___FILEBASENAMEASIDENTIFIER___ : ___VARIABLE_cocoaTouchSubclass___

@end

To this:

//
//  ___FILENAME___
//  ___PROJECTNAME___
//
//  Created by ___FULLUSERNAME___ on ___DATE___.
//  Copyright (c) ___YEAR___ ___ORGANIZATIONNAME___. All rights reserved.
//

___IMPORTHEADER_cocoaTouchSubclass___

@interface ___FILEBASENAMEASIDENTIFIER___ : ___VARIABLE_cocoaTouchSubclass___ {
@private

}
@end

Poke around in /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/ and /Developer/Library/Xcode/Templates/File Templates to see more templates you can customize.

Or use this python script I wrote to customize them all automatically (after tweaking the python script to fit your customization needs):
