Hello again,
So, they are two issues. The crash and the iCloud sync dealing with this new @Attribute "trasformables" that Apple change for us and thus, provoking this mess.
In all honestly, Apple is the one that should be making the Tweaks, not us. In-memory models should respect the existing data store of our Apps since they are already being used by thousands of users in realtime.
Someone above probably doesn't want to deal with the iOS26.2 publishing date (it's in the final stages) and that is the wrong decision. Why do we have to clean the mess when Apple made our code incompatible? 😒. Makes no sense. **
** Are you aware how many weeks of work it will take for us to refactor all of our Apps using this confusing tweak with decodables? Sorry but your solution is not acceptable.
