Adding cloud saves on iOS would a great improvement for the game on that platform and add two significant features:
- Saves would no longer be lost when the game is uninstalled. Currently if you uninstall Stardew on iOS without backing up your saves, you lose them.
- Saves would be synced across all iOS devices signed in to that iCloud account. Much like Steam cloud sync allows for people with multiple computers to play their saves anywhere and keeps everything synced, adding cloud saves on iOS would do the same for people with both an iPhone and iPad.
