iOS swift中比较模型数组是否相等

在oc中，如果要比较模型数组中的元素是否相等一般重新isEqual方法即可

-(BOOL)isEqual:(id)object{
    if (self == object) {
        return YES;
    }
    if ([object isKindOfClass:[self class]]) {
        HXQHoldWorthModel *obj = (HXQHoldWorthModel *)object;
        
        return self.holdCount == obj.holdCount &&
        [self.userImg isEqualToString:obj.userImg]&&
        [self.realname isEqualToString:obj.realname]&&
        self.totalValue == obj.totalValue;
    }else{
        return NO;
    }
}-(BOOL)
