CoreData batch insert Entities with Relationship - swift

Question

Is there anyway to insert entities with relationship? I get error "Illegal attempt to establish a relationship 'content' between objects in different contexts"
addUsers(users: [userData])
func addUsers(users: [User]) {
let taskContext = container.viewContext
taskContext.perform {
let batchInsertRequest = self.newBatchInsertRequest(with: users)
if let fetchResult = try? taskContext.execute(batchInsertRequest),
let batchInsertResult = fetchResult as? NSBatchInsertResult,
let success = batchInsertResult.result as? Bool, success {
return
}
}
}
crash happens in below code
private func newBatchInsertRequest(with users: [Users]) -> NSBatchInsertRequest {
var index = 0
let total = message.count
let batchInsertRequest = NSBatchInsertRequest(entity: WaUser.entity(), managedObjectHandler: { managedObject in
guard index < total else { return true }
let user = users[index]
if let waUser = managedObject as? WaUser {
waUser.name = user.name
let waUserInfo = waUserInfo(context: self.container.viewContext)
waUserInfo.pass = "12345"
waUserInfo.key = "asdfgh"
waUser.info = waUserInfo **//crash occurs here**
}
index += 1
return false
})
return batchInsertRequest
}
