val df = spark.read.format("csv").load("inputpath")
df.rdd.map(i => i.mkString.split("\\[\\~\\]")).toDF().show(false)

try below

for your another requirement

val df1 = df.rdd.map(i => i.mkString.split("\\[\\~\\]").mkString(",")).toDF()
val iterationColumnLength = df1.rdd.first.mkString(",").split(",").length
df1.withColumn("value",split(col("value"),",")).select((0 until iterationColumnLength).map(i => col("value").getItem(i).as("col_" + i)): _*).show
