Obj-C 2.0 Error Msg decoded #1

The error message in question is this clear piece of literature:

error: synthesized property 'X-Factor' must either be named the same as a compatible ivar or must explicitly name an ivar

Wow - what a mouthful - as Jinx would say.

Here's a very cut down example that would give the error message in question

@interface MyClass : NSObject

{

}

@property (readwrite) BOOL X-Factor;

@end

@implementation MyClass

@synthesize X-Factor;

@end

Short huh? Can you see what the problem is - hopefully it's obvious in this example with all the other extraneous code cut away.

Our interface block (typically in the your ".h" header file) defines a property for the compiler called X-Factor and the implementation block (typically in your ".m" class file) directs the compiler to synthesize (ie. create) the setter and getter methods for an iVar called X-Factor.

Hang on though - our code block doesn't actually declare an iVar now does it? So, does the error message make a bit more sense to you?
Personally I think the error message could be re-written as:

error: No matching declaration in Interface block for synthesized property 'X-Factor'

To fix of course, our interface block needs this line added to it:

BOOL X-Factor;

There you go all fixed!
