Query on RLMArray containing NSString crashes.

[Gawetaner]

Goals

Query all objects that contain a specific string in a RLMArray property.

Expected Results

The result contains all objects which contain the specific string in their RLMArray property.

Actual Results

The query throws an exception:

Expected object of type (null) for property 'strings' on object of type 'RealmObject', but received: 1

Steps to Reproduce

1. Create a new ObjC iOS Project
2. Add Realm as dependency
3. Paste the sample code into AppDelegate.m
4. Start the App

Code Sample

#import "AppDelegate.h"

// Frameworks
#import <Realm/Realm.h>

@interface RealmObject : RLMObject

@property (nonatomic) RLMArray <NSString *> <RLMString> *strings;

@end

@implementation RealmObject

+ (NSArray<NSString *> *)requiredProperties
{
    return @[NSStringFromSelector(@selector(strings))];
}

@end

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    RealmObject *object1 = [RealmObject new];
    [object1.strings addObjects:@[@"1"]];

    RealmObject *object2 = [RealmObject new];
    [object2.strings addObjects:@[@"2"]];

    RealmObject *object3 = [RealmObject new];
    [object3.strings addObjects:@[@"3"]];

    RLMRealm *realm = [RLMRealm defaultRealm];
    [realm transactionWithBlock:^{
        [realm deleteAllObjects];
        [realm addObjects:@[object1, object2, object3]];
    }];
    
    RLMResults *results = [RealmObject objectsWhere:@"%@ IN SELF.strings", @"1"];
    NSLog(@"%@", results);
    
    return YES;
}
@end
