How to remove the first word of a string?

> 
> 0.91% ABC DEF  
> 
>  0.922% ABC DEF GHI
> 
> 
> OUTPUT: ABC DEF / ABC DEF GHI
> 
> 
> 

I tried

```
let test = str.split(separator: " ")[1...]
print(test)
print(test.joined(separator: " "))

```

Which gives me: 

```
["ABC", "DEF"]
JoinedSequence<ArraySlice<Substring>>(_base: ArraySlice(["ABC", "DEF"]), _separator: ContiguousArray([" "]))

```

How can I print the JoinedSequence as a string?
