I need to concatenate a `String` and `Int` as below: ``` let myVariable: Int = 8 return "first " + myVariable ``` But it does not compile, with the error: Binary operator '+' cannot be applied to operands of type 'String' and 'Int' What is the proper way to concatenate a String + Int?

Accepted Answer

If you want to put a number inside a string, you can just use String Interpolation:

```
return "first \(myVariable)"
```
