Fatal error: Can't form Range with upperBound < lowerBound: file <directory>

**Fatal error: Can't form Range with upperBound < lowerBound: file **

I couldn't compile the next very simple code

`// Modifiable Parameters`

```
func theString(_ arrayOfStrings:String ...) {
for s in arrayOfStrings {print (s)}
}

theString("Hello", "Hello, World!", "Nooooo!")

```

**It should have printed **

```
Hello
Hello, World!
Noooo!
```

macOS Catalina, VS Code version 1.46.1

**Compiler throws at me this:**

```

Il report non indica alcun file del repository, test o punto di ingresso. Inizia riproducendo il comando Swift 5.2.2 mostrato in VS Code Code Runner su macOS Catalina, quindi confrontalo con l'esecuzione diretta dello stesso codice sorgente usando swift. Il lavoro è completato quando si determina se l'invocazione di Code Runner causa il crash e si registra una riproduzione minima e utilizzabile.

Scritto dal modello di indicizzazione a partire dal testo della issue.
