Why does 𝐶𝑜𝑑𝑎𝑏𝑙𝑒 work for 𝑈𝑠𝑒𝑟𝐷𝑒𝑓𝑎𝑢𝑙𝑡𝑠 initially but break during migrations? This article explains the pitfalls when models change and presents an alternative approach using individual properties.

👋🏾 I’m seeking recommendations for other libraries similar to Zephyr (https://github.com/ArtSabintsev/Zephyr) that simplify syncing UserDefaults across iCloud.
There are a few folks talking about the same issue:
An older Apple dev forum thread about prewarming (is this still relevant?)
https://forums.developer.apple.com/forums/thread/667959?page=2
StackOverflow post where folks blame a missing privacy manifest, but that doesn’t make sense does it?

The problem with lots of progress over the weekend.. is lots of write up too! So many typos... but Lines now has a button that acts just like the paste button but uses an AppGroup and UserDefaults behind the scenes instead of the Pasteboard.

#SwiftLang, #WebExtension, #SafariWebExtension, #NativeApp, #JavaScript, #AppGroup #UserDefaults
Recent #iOS development journal on data #persistency
1. Implemented everything with #UserDefaults and raw file system
2. Feeling in need of a higher level abstraction
3. #SQLite is too much for now, and I don't want to bother with schema migration on a client device
4. Core Data looks what I need, but friends warned me to avoid it
5. #GRDB seems to hold a good reputation comparing to Core Data
6. Let me try Core Data, it seems to improved a lot recently
Mac/iOS devs! PLEASE prefix your user defaults keys!
User defaults are combined in layers. So system settings like your app's accent color are inserted into your user defaults, even if you don't see them in the .plist file.
While Apple has recently switched to prefixes like ‘NS’ and ‘com.apple.’ for their defaults keys, I've seen keys in the past there that were very simple and un-prefixed. The expectation was your app would use the same prefix it used in ObjC.
