How to resolve a type mismatch with?

This is not so much a GRDB issue as a swift type problem. I've tried sever of things to get this right and just can't come up with anything that works. I also tried asking on the Apple Developers forum but no resolution there. Can anyone tell me how to resolve this or a better way to code this? When I try to assign rowsFetched I get a type mismatched?

I have the following function:

func getAllCustomers() -> NSArray {
var rowsFetched: NSArray
do {
try { db in

  •        let custlist = try Customers.fetchAll(db)*
  •        rowsFetched = cultist* ---->>> gets a type mismatch
    } catch {

Indeed. Will you please ask this question in the Using Swift forum instead?

You bet!
