iOS Swift: Delete parse array item referenced by index -

i have data stored in parse column following column keys

phone = ["iphone", "galaxy s6", "nexus"]

quantity = [20, 30, 20]

boolv = [[true, false], [true, false], [false,true]]

i presenting date in tableview format user , want give him option delete these items.

at present following this: inside tableview commiteditingstyle function

// find index value of user selected cell var indexvalue = find(phone, "iphone") // 0 // using this, can delete array elements phone quantity.removeatindex(indexvalue!) boolv.removeatindex(indexvalue!) 

to delete parse using following:

object.removeobject("iphone", forkey: "phone") // works fine object.removeobject("self.quantity[indexvalue]", forkey: "quantity") // deletes both "20" quantity table object.removeobject("self.boolv[indexvalue]", forkey: "boolv") // again deleted both "[true, false]" values form array. 

i sure missing here. want delete array item pointed indexvalue. how can in parse? appreciated. thanks.

this seems should use different data model 2 classes , relationship rather 1 class , set of array attributes. then, deletion remove item relationship , delete data store.

the way have @ moment can't delete individual items array, need take array, edit , store full new updated array.
