Check empty string in Swift?

Question

In Objective C, one could do the following to check for strings:

if ([myString isEqualToString:@\"\"]) {
    NSLog(@\"m         


        

Answer 1

Here is how I check if string is blank. By 'blank' I mean a string that is either empty or contains only space/newline characters.

struct MyString {
  static func blank(text: String) -> Bool {
    let trimmed = text.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines)
    return trimmed.isEmpty
  }
}

How to use:

MyString.blank(" ") // true
