| | Planning ahead for Upgrades - Question
Please Login to Remove!
I've noticed that when I add new properties and/or methods to the classes in my app, the app crashes. It seems as though that's because the data that's on the device (still running in the simulator) doesn't fit well with the updated class).
Can someone offer some advice on dealing with the inevitable upgrades? I really dread the thought of having to "upgrade" the data from who knows what version to the current version.
If it was always upgrading from the most recently published version to the new one, that wouldn't be too bad. But there's no way to be sure that the user has the latest version installed.
