Inspectopedia Help

Return or assignment can be lifted out

Reports if, when, and try statements that can be converted to expressions by lifting the return statement or an assignment out.

Example:

fun foo(arg: Int): String { when (arg) { 0 -> return "Zero" 1 -> return "One" else -> return "Multiple" } }

After the quick-fix is applied:

fun foo(arg: Int): String { return when (arg) { 0 -> "Zero" 1 -> "One" else -> "Multiple" } }

If you would like this inspection to highlight more complex code with multi-statement branches, uncheck the option "Report only if each branch is a single statement".
