Goals

Be able to open a realm database which has been initialized on a mac catalyst app in an iOS app.

Expected Results

  • Initialization of an encrypted realm database in a mac catalyst app
  • Database file transfer to a device with iOS
  • Be able to decrypt this file and use the realm database in the iOS app

Actual Results

Realm is unable to open the realm file using the same encryption key as the mac catalyst app.

`Unable to open a realm at path '/var/mobile/Containers/Data/Application/7A059308-3BEF-4F19-843E-2D1176473B89/Documents/my_encrypted_realm.realm': Realm file decryption failed Path:Exception backtrace:

Hi @RomainPct,

Thank you for providing information about your issue including the code repo.

I checked it out and could not reproduce the issue immediately. In fact I got a completely different result.

The relevant part:

40 libdyld.dylib 0x0000000199a81588 E31C0887-C999-3047-9B80-203248EC2396 + 5512, NSLocalizedDescription=Unable to open a realm at path '/var/mobile/Containers/Data/Application/DBE04462-6B17-4E0F-80CC-BEB821B5D116/Documents/default.realm': Realm file decryption failed Path:Exception backtrace:

We will have to look further into this.

Same error for both of us @DominicFrei "Unable to open a realm at path ...: Realm file decryption failed"
Do you have any idea about how to solve that problem N

Closing as this is not something that is actually supported. See: realm/realm-core#4518 (comment)
