How do I handle errors and retries with Core Data in Swift?

Handling errors and retries in Core Data is crucial to ensure the integrity of your app's data. Using proper error handling mechanisms can help you catch any issues that arise during data operations and implement retry logic where necessary.

Example of Error Handling and Retry Mechanism

Here’s an example of how to manage Core Data operations using a retry mechanism in Swift:


        import CoreData

        func saveContext() {
            let context = persistentContainer.viewContext

            if context.hasChanges {
                do {
                    try context.save()
                } catch {
                    let nserror = error as NSError
                    print("Unresolved error \(nserror), \(nserror.userInfo)")
                    handleCoreDataError(error)
                }
            }
        }

        func handleCoreDataError(_ error: Error) {
            // Retry logic
            let retryLimit = 3
            var retries = 0
            var success = false

            while retries < retryLimit && !success {
                do {
                    try persistentContainer.viewContext.save()
                    success = true
                } catch {
                    retries += 1
                    if retries == retryLimit {
                        print("Error saving data after \(retryLimit) attempts: \(error)")
                    }
                }
            }
        }
