# E
Swift... but only enums!
**[About Swift Enumerations](https://docs.swift.org/swift-book/LanguageGuide/Enumerations.html)**
## Variables
### Basic String Example
```swift
let text: Variable = .string("Hello, World!")
```
### Basic Dictionary Example
```swift
let dictionary: Variable = .dictionary(
[
.bool(false): .double(3.14)
]
)
```
### Array Example
```swift
let list: Variable = .array(
[
.bool(false),
.string("False"),
.dictionary(
[
.bool(false): .double(3.14)
]
),
.int(27)
]
)
```
### Getting Values Example
```swift
if case .string(let value) = text {
print("String: \(value)")
}
if case .array(let value) = list,
let lastValue = value.last,
case .int(let number) = lastValue {
print(number * 99)
}
```
## Functions
### Void Function Example
```swift
let voidExample = Function.void {
print("Print Lorem ipsum")
}
// ...
voidExample()
```
### In Function Example
```swift
let printString = Function.in { stringValue in
guard case .string(let value) = stringValue else {
return
}
print(value)
}
// ...
printString(.string("Hello, World..."))
```
### In & Out Function Example
```swift
let double = Function.inout { value in
if case .int(let value) = value {
return .int(value * 2)
} else if case .float(let value) = value {
return .float(value * 2)
} else if case .double(let value) = value {
return .double(value * 2)
} else if case .string(let value) = value {
return .string("\(value)\(value)")
}
return .array([value, value])
}
// ...
print("Double of \(Variable.float(3.14)) is \(double(.float(3.14)))")
```
