@chrisrbailey: This might work:

@DynamoDBTable(tableName="Installations")
class Installation(
    @DynamoDBHashKey(attributeName="device")
    var device: String = "",

    @DynamoDBRangeKey(attributeName="app")
    var app: String = "",

    @DynamoDBAttribute(attributeName="platform")
    var platform: String = "",

    @DynamoDBAttribute(attributeName="user")
    var user: Int? = null
)
