CloudKitEncryptable is built off of CloudKitCodable and provides a simple way to encrypt properties in your CKRecords.
The type whose properties you want to be encrypted in CloudKit should conform to CloudKitEncryptable, and you should list the coding keys that correspond to the properties you want encrypted in the static property encryptedProperties.
Additionally, any properties you want to encrypt should conform to DataRepresentable. This package extends URL, String, Bool, Int, Double, and Date, making them conform to DataRepresentable. If you need other types to be encryptable, ensure that they conform to DataRepresentable.
When you want to create your CKRecord, use CKEncryptedRecordEncoder.
When you want to convert CKRecord objects to your Swift types, us CKEncryptedRecordDecoder.
Additional CloudKitCodable functionality is provided as described here.
