# die
Terminating a Swift application with style:
```swift
func die(_ message: @autoclosure () -> String, file: StaticString = #file, line: UInt = #line) -> T {
preconditionFailure("💥 " + message(), file: file, line: line)
}
```
## Usage
Application or Playground:
```swift
let name: String? = nil
print(name!)
// Fatal error: Unexpectedly found nil while unwrapping an Optional value
```
```swift
let name: String? = nil
print(name ?? die("A girl has no name."))
Fatal error: 💥 A girl has no name: file MyPlayground.playground, line 5
```
Swift REPL:
```
1> let name: String? = nil
name: String? = nil
2> print(name!)
Fatal error: Unexpectedly found nil while unwrapping an Optional value

## Instalation
Copy the method above and paste it in your code. If you are not fond of the name `die()`, please rename it to something else. You can even use emoji:
```swift
print(name ?? 💣("A girl has no name"))
```
