Backup / Restore

[JoeMatt]

Somewhat related to #1 but not a full syncing solution.

Work in Progress Ticket

This falls into 2 categories:

1. iCloud automatic backup For this to really work correctly we need to respect the directory guidelines, https://developer.apple.com/icloud/documentation/data-storage/index.html

ie; ROMs, BIOSes etc should be moved out of Documents, but save states and Realm should stay there

• User genereated artwork should stay in documents
• Artwork that can be redownloaded (default artwork) should be in Caches
• Roms should be in Caches (possibly add an option to not auto-delete by marking ROMs flagged as favorite with the 'do not back up' but leave in Documents (this causes the roms to not be deleted but not included in backups.

2. Manual Backup / Restore

Manually allow backup of Realm, Saves, Custom Images Use a framework to allow different locations https://github.com/amosavian/FileProvider

Example code for locking realm DB temporarily.

let containerURL = FileManager.default.url(forUbiquityContainerIdentifier: nil)
let realmArchiveURL = containerURL.appendPathComponent("MyArchivedRealm.realm")

let realm = try! Realm()
try! realm.writeCopy(toFile: realmArchiveURL)

Research TODO:

• Try out IceCream maybe https://github.com/caiyue1993/IceCream

• Is iCloud backup working? Does it work with side loaded apps at all?

• Entitlements for iCloud Drive

  • Can be automated creating the containers, app bundle ids using fastlane
  • https://docs.fastlane.tools/actions/update_app_group_identifiers/

• Do something about hard coded PVAppGroupId

• Realm DB moved?

• resign? for changing prov pfoiel entitlements https://docs.fastlane.tools/actions/resign/
