Question

Knowing that from Xcode4 and LLVM 2.0 there is the new feature “@syntesize by default”

I tried the following code:

@interface PDFPage : NSObject

@property (nonatomic,copy) NSString *name;
@property (nonatomic,assign) int page;

@end

@implementation PDFPage

-(void)dealloc
{
    [self.name release];
    [super dealloc];
}

@end

I assumed that @synthesize was no longer necessary but the compiler (Apple LLVM 2.1) give me a warning like ‘warning: property ‘page’ requires method ‘page’ to be defined – use @synthesize, @dynamic or provide a method implementation’

What else I need to do to enable @synthesize by default ? (I also tried the flags -Xclang -fobjc-nonfragile-abi2 but they are not recognized).

Thank you

Apple removed the automatic @synthesize feature from the non-fragile ABI because of issues it was causing or uncertainties the compiler had when trying to autosynthesize properties. See this blog post for more information about it.
