How do I merge offline changes on reconnection in Swift?

Merging offline changes upon reconnection is an important aspect of building robust applications that work seamlessly across different network conditions. In Swift, you can manage offline changes by storing them temporarily and then merging when the connection is re-established. Here’s a simple approach to achieve this:

/* Assuming you have a data structure to hold unsynchronized changes, and a method to apply changes once reconnected: */ class DataManager { var offlineChanges: [Change] = [] var isConnected: Bool = false func applyChange(_ change: Change) { if isConnected { // Apply the change to the main data store saveChange(change) } else { // Store changes offline offlineChanges.append(change) } } func reconnect() { isConnected = true mergeOfflineChanges() } private func mergeOfflineChanges() { for change in offlineChanges { saveChange(change) // This method applies the change } offlineChanges.removeAll() } private func saveChange(_ change: Change) { // Logic to save the change } }
