iCloud backup issue

[kaszap82]

First of all sorry for my bad Engish.

I have a project with DATAStack. A lot of users have a problem, when they set a new iPhone from iCloud backup. The data strored in CoreData doesn't exists on the new phone. Should I have to set something to "tell" Apple, that they should backup the sql file? Did you hear about similar issues?

Thanks for your help!

Hi @kaszap82,

This was a conscious choice, I experienced many rejections based on Apple telling us that I shouldn't be backing up sqlite, so I set a flag so this doesn't happen.

This was some time ago, I believe there's approved alternatives by Apple to backup your data, if you find something I'll be glad to include it in the library :)

Isn't this only true for Default Data Stores, shipped with the app? It should not be applied to user data stores. If our users buy a new iPhone or iPad and restore from a iCloud backup they would expect that the data for our app was restored as well.

At least, could it be an option when we initialize the data stack so that we could decide by our self if the flag should or shouldn't be used.

That's a good point, it can be made optional. Any chance you could look into it? 🙏

Sure, I can look into it. Don’t know how much time I have before the holidays but I will do it as soon as I can.

@3lvis Should it be excluded or included in the backup by default? I would say it should be included in the backup. So that you have to specify if you have a default store that should be excluded.

@3lvis Any change you could have a look at the pull request?

[3lvis]

Merged!

Let me know if it works as expected, I made it excluded by default to not break existing functionality.

Thanks for your contribution 🎉
