Spark 3.0 DataFrame foreachPartition method does not work

Question

The following code

val df = List(1,2,3,4,5).toDF()
df.foreachPartition(p => p.foreach(println(_)))

Works well in spark 2.4 with scala 2.11, but with Spark 3.0 with scala 2.12, it failed with this error:

error: value foreach is not a member of Object
df.foreachPartition(p => p.foreach(println(_)))
