How to compare two strings in swift?

Question

I have the following problem:

I want to compare if one string contains "Schreibe etwas..."

I solved it with the following code:

selectedText = postTextView.text!
let isText = selectedText

if isText != "Schreibe etwas..." {
    shareButton.isEnabled = true
    abortButton.isEnabled = true
}

But its not working. How to solve this problem?

Thanks in advance for your help!

What is `isText` ? BTW, this is right way to compare string. — Mayur Karmur, Dec 19 '18 at 12:48

You can try

if !isText.contains("Schreibe etwas...") {
    shareButton.isEnabled = true
    abortButton.isEnabled = true
}

use this code to compare two String

  var a : String = "Schreibe etwas..."
  var b  : String = "Schreibe etwas..."

  if(a.caseInsensitiveCompare(b) == .orderedSame){
      print("string is Same")
  }
