<br>
I'm seeing a weird issue with using an initializer in flatMap. Here's<br>
an example:<br>
<br>
```<br>
let time: TimeInterval? = 662.82582598600004<br>
let intTimeFlatmap = time.flatMap(Int.init) // nil<br>
let intTime = Int(time!) // 662<br>
```<br>
<br>
I would expect for the flatMap call to return an optional Int with the<br>
proper value of 662. Is there something I'm misunderstanding, or is<br>
this a swift bug?<br>
<br>
Thanks,<br>
Halen<br>
