Kotlin does not require semicolon at the end of each statement or expression line. Associated 'Remove redundant semicolon' quick-fix allows to amend the code.

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 ';' is required:

1. Statements placed on a single line need to be separated with semicolon:

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

2. 'enum' class having a list of enums and also properties or functions requires ';' after the enum list:

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