You can check the number of characters in the AttributedString. So in your case, to check if the remark is not empty, do this:

if !remark.characters.isEmpty {
  // show your view
}

(lldb) po remark?.characters.count ▿ Optional<Int> - some : 3

it will always return false because remark have 3 spaces

That does not make sense. Why does it have 3 spaces? This works fine:

swift var string = AttributedString("hello") print(string.characters.count) // returns 5  string = AttributedString("") print(string.characters.count) // returns 0

If you know that it has 3 spaces, just check whether all characters are 3 spaces and take a decision based on that
