Answer 1

You can create a URL rather rather than a String path.

let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first
let fileURL = documentsURL?.appendingPathComponent("test.sqlite")

If you absolutely need the path, then you can get it like this:

guard let path = fileURL?.path else {
    return
}

print(path) // path will exist at this point

There was some discussion in the thread you mentioned that Apple may be purposely guiding people toward using URLs rather than String paths.

Answer 2

You can use:

let dbPath = (documentsFolder as NSString).stringByAppendingPathComponent("db.sqlite")
