size == 0 checks on Collections/Array/String that should be replaced with isEmpty().
Using isEmpty() makes your code simpler.
The quick-fix replaces the size check with isEmpty().
Example:
fun foo() {
val arrayOf = arrayOf(1, 2, 3)
arrayOf.size == 0
}
After the quick-fix is applied:
fun foo() {
val arrayOf = arrayOf(1, 2, 3)
arrayOf.isEmpty()
}
