@Suppress("HEADER_WITHOUT_IMPLEMENTATION").
Some of diagnostics from Kotlin 1.2 and earlier are now obsolete, making such suppressions redundant.
Example:
@Suppress("HEADER_DECLARATION_WITH_BODY")
expect fun connection() {
// ...
}
After the quick-fix is applied:
@Suppress("EXPECTED_DECLARATION_WITH_BODY")
expect fun connection() {
// ...
}
