Is there a way to get guard to setup a let in the first part and then a conditional on the second part?
guard let tags = item.tags && tags.count > 0 else {
return
}

I've only been using Swift for 3 days so…:)
You can do:
guard let tags = item.tags where tags.count > 0 elseThe general syntax of a 'let' test is a series of clauses separated by commas. Each clause is of the form 'let var = initializer where constraint', except that the first clause may alternatively be a pure boolean expression (no 'let') if you wish — and the 'where' constraint is optional, of course.
