To implement resumable file downloads on Apple platforms, you can utilize the concept of resumable queries as discussed in the session "Meet FinanceKit" at WWDC 2024. Although this session primarily focuses on financial data, the principles of handling resumable operations can be applied to file downloads as well.
In the context of resumable queries, the session suggests persisting a history token to disk every time a new change is processed. This token can then be used to resume the query from where it left off, eliminating duplicated events. For file downloads, a similar approach can be taken by saving the state of the download (such as the last byte received) and using this information to resume the download if it is interrupted.
For more detailed information on handling resumable operations, you can refer to the session Meet FinanceKit (20:36).
