App crash using iCloud Key-Value storage writing

Question

My app crashes every time I try to set a value for a key using iCloud key-value storage...

I get this error:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason:     '[<NSUbiquitousKeyValueStore 0x13fd5b8a0> setValue:forUndefinedKey:]: this class     is not key value coding-compliant for the key ladies.'

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb) 

I define my keystore:

var iCloudStore = NSUbiquitousKeyValueStore.defaultStore()

Set my value like this:

iCloudStore.setValue(experience, forKey: "experience")

Why is this not working? Do I have to define that key for it to work? I really don't understand the error i get...

Answer 1

setValue:forKey: is not a method on NSUbiquitousKeyValueStore.defaultStore() used to save data to an iCloud key-value store. Instead, it is the method from the NSKeyValueCoding protocol that is used for more general key-value coding with the types NSValue and NSNumber. The error you received refers to you attempting to access the “experience” key on your iCloudStore object itself rather than in the iCloud key-value store.

The methods available on NSUbiquitousKeyValueStore.defaultStore() to save key-value pairs are:

• setArray:forKey:
• setBool:forKey:
• setData:forKey:
• setDictionary:forKey:
• setDouble:forKey:
• setLongLong:forKey:
• setObject:forKey:
• setString:forKey:

Choose the method that best fits your type.
