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