Initializing Realm from background thread causes data race warnings

[TomasLinhart]

How frequently does the bug occur?

Always

Description

Object._getProperties() and EmbeddedObject._getProperties() are annotated with @MainActor, but if you initialize Realm from a background thread. For example, using DispatchQueue.global().async. These methods will be called from the same thread that was used to initialize Realm.

It happens only if you build Realm as a debug build via Carthage, because you set SWIFT_STRICT_CONCURRENCY to complete.

I would either expect Realm.init to be on the main actor too or the methods not requiring the main actor.

Can you reproduce the bug?

Always

Ah, those annotations are just incorrect.
