Hi, I am starting to integrate your excellent project into my app.
I am now facing a problem.

How do I save to the database synchronously?
I need realtime saving.

I need to replace this function

do {
try MY_OBJECT.managedObjectContext?.save()
} catch let error {
fatalError("Failure to save context: (error)")
}

I thank you in advance for your response.
Thank you

I wouldn't recommend using synchronous transactions as they may cause deadlocks. But if you are confident about how you use it, CoreStore does expose a DataStack.performSynchronous() method.

Hi, this is the code I am using to save data without async.
Is the method correct?

try? DataStack.perform(
synchronous: { (transaction) in
guard let localDATA= try? transaction.fetchOne(From(),Where("self == %@", data.objectID )) else {
return
}
localDATA.data = value_for_data
},
waitForAllObservers: false
)

Alternatively how can I save data?
Can you give me an example please.
Thank you
