Range can be converted to indices or iteration

Reports until and rangeTo operators that can be replaced with Collection.indices or iteration over collection inside for loop.

Using syntactic sugar makes your code simpler.

The quick-fix replaces the manual range with the corresponding construction.


fun main(args: Array<String>) { for (index in 0..args.size - 1) { println(args[index]) } }

After the quick-fix is applied:

fun main(args: Array<String>) { for (element in args) { println(element) } }
