The feature moves backups from an internal SSD to an external hard drive and includes a cancel mechanism and smooth progress updates. While the AI tools significantly reduced development time, they struggled with modern Swift features like Concurrency. The experience highlights that AI tools are best for new features rather than complex logic, making them helpful but not yet a replacement for human developers.
