```swift
struct NowTagError: Error {}
let formatter = DateFormatter()
switch ctx.parameters.count {
case 0: formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
case 1:
guard let string = ctx.parameters[0].string else {
throw NowTagError()
}
formatter.dateFormat = string
default:
throw NowTagError()
func render(_ ctx: LeafContext) throws -> LeafData {
let formatter = DateFormatter()
switch ctx.parameters.count {
case 0: formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
case 1:
guard let string = ctx.parameters[0].string else {
throw NowTagError()
}
formatter.dateFormat = string
default:
throw NowTagError()

let dateAsString = formatter.string(from: Date())
return LeafData.string(dateAsString)
}
let dateAsString = formatter.string(from: Date())
return LeafData.string(dateAsString)
