(Swift) Is it recommended to hang on to a synced realm instance? Or re-get it every time?

I’ve been using non-synced realms for a few apps, and I generally call

let realm = try Realm()
// do something...

every time I want to do something with data in the realm.

However, when working with synced realms, should I be calling

let realm = try await Realm(configuration: syncedConfiguration)
// do something

every time as well? It feels like the call to Realm(configuration: syncedConfiguration) is expensive, but i’m just guessing here.

If we should change the behavior for synced realms, where should we store the realm?

Thanks!
