RLMThreadSafeReference

@interface RLMThreadSafeReference < __covariant Confined
    : id <RLMThreadConfined>
> : NSObject @end

An object intended to be passed between threads containing a thread-safe reference to its thread-confined object.

To resolve a thread-safe reference on a target Realm on a different thread, pass to -[RLMRealm resolveThreadSafeReference:].

Warning

A RLMThreadSafeReference object must be resolved at most once. Failing to resolve a RLMThreadSafeReference will result in the source version of the Realm being pinned until the reference is deallocated.

Note

Prefer short-lived RLMThreadSafeReferences as the data for the version of the source Realm will be retained until all references have been resolved or deallocated.
