I also had duplicate symbols. I just renamed the procedure (app -> app1, app2) and the associated fields app.XXX -> app1.XXX . and it worked !

See : (in a .m file)

AppDelegate* app1;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        app1 = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    }
    return self;
}

(...)

- (int) getLimit
{
    if (app1.product2buyed)
        return MAXID;
    else if (app1.product1buyed)
        return 70;
    else
        return 10;
