[RudifaUtilPkg](https://rudifa.github.io/RudifaUtilPkg/) contains swift extensions and utility methods.

## Highlights

### FileBackedDictionary

 `struct FileBackedDictionary`  encapsulates a `[String:T]` dictionary whose values are automatically persisted, each in its own file.

 `FileBackedDictionary` exposes methods and properties similar to those of the Swift Dictionary.

 At its initialization (typically at the application start), an instance of `FileBackedDictionary` recovers the keys and values from the file storage (if any have been stored in previous application runs).

### Usage examples ###

 Create a `FileBackedDictionary` instance, with a directory named `MyResources` and `struct Resource` as type of the values to store.

```

        let directoryName = "MyResources"

        var fbDict = FileBackedDictionary(directoryName: directoryName)

```

 Add `Resource` instances

```

        fbDict["apples"] = Resource(name: "apples", value: 1, quantity: 1)

        fbDict["oranges"] = Resource(name: "oranges", value: 2, quantity: 2)

        fbDict["mangos"] = Resource(name: "mangos", value: 3, quantity: 3)

```

 Look up the resource info

```

        let count = fbDict.count			// 3

        let keys = fbDict.keys			// ["apples", "oranges", "mangos"])

        let values = fbDict.values 		// [...]

        let myOranges = fbDict["oranges"]

```

 Remove resources

```

        fbDict["oranges"] = nil

        fbDict.removeAll()

```
