Crash when accessing obj by its int primary key (0.91.3 -> 0.93.0)

[rsahara]

I just tried to update from 0.91.3 to 0.93.0 and encountered the following crash.
Is there something wrong with my code?

The view looks like this:

• A UICollectionView is holding an NSArray of RLMObject representing products.
• Each cell shows a product with its brand name. (RLMObject of brand, with brandId as primary key)
  After scrolling a few pages of the UICollectionView, the app crashes when accessing the brand model.

Code calling RLMObject

-(ModelBrand*)brandById:(int)brandId
{
    return [ModelBrand objectInRealm:_cacheDb
                       forPrimaryKey:[NSNumber numberWithInt:brandId]];
}

Model

@interface ModelBrand : RLMObject

@property NSDate*       modelUpdate;
@property int           brandId; // key
@property NSString*     brandName;
@property NSString*     brandNameIndex;
@property int           brandType;
@property int           status;
@property int           siteId;
@property BOOL          open;
@property BOOL          recommended;

@end

// impl

+ (NSString*)primaryKey
{
    return @"brandId";
}

+ (NSDictionary *)defaultPropertyValues
{
    return @{
             @"modelUpdate":[NSDate date],
             @"brandId":@0,
             @"brandNameIndex":@"",
             };
}

Thanks.

This should now be fixed with #2024. We intend to release a new version including the fix shortly.

Thanks! Will check again once released.
