I need to filter using `IN`. Here is my code:

```
let choices = "1,2,3,4"

```

Then use it like this, which crashes the app:

```
NSPredicate(format: "id in %@", @choices)

```

I've also tried:

```
NSPredicate(format: "id in [1,2,3,4]")

```

But get this error:

```
'Unable to parse the format string "id in [1,2,3,4]"'

```
