Unused loop index

Reports for loops iterating over a collection using the withIndex() function and not using the index variable.

Use the "Remove indices in 'for' loop" quick-fix to clean up the code.

Examples:

fun foo(bar: List<String>) { for ((index : Int, value: String) in bar.withIndex()) { // <== 'index' is unused println(value) } }

After the quick-fix is applied:

fun foo(bar: List<String>) { for (value: String in bar) { // <== '.withIndex()' and 'index' are removed println(value) } }
