viewing coredata with sqlite browser in xcode 5
In iOS 7 SQLite's Write-Ahead Logging is turned on by default. In this mode data is split into three files (.sqlite, .sqlite-shm, .sqlite-wal). I've seen that some SQLite viewers ignore .sqlite-shm and .sqlite-wal files, thus not showing proper data.
I'm using SQLite Manager plugin in Firefox, it works pretty decent.
You can get the plugin here https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/
After you install the plugin you will see 'SQLite Manager' (with a database icon in blue color) item in Tools menu.
