Kotlin does not require a semicolon at the end of each statement or expression. The quick-fix is suggested to remove redundant semicolons.

Example:

  val myMap = mapOf("one" to 1, "two" to 2);
  myMap.forEach { (key, value) ->  print("$key -> $value")};

After the quick-fix is applied:

  val myMap = mapOf("one" to 1, "two" to 2)
  myMap.forEach { (key, value) ->  print("$key -> $value")}

There are two cases though where a semicolon is required:

1. Several statements placed on a single line need to be separated with semicolons:

   
     map.forEach { val (key, value) = it; println("$key -> $value") }
   

2. enum classes that also declare properties or functions, require a semicolon after the list of enum constants:

   
     enum class Mode {
         SILENT, VERBOSE;
   
         fun isSilent(): Boolean = this == SILENT
     }
