i have dictionary , adding tableview.

 let myarray = [["name": "first element", "foo": "bar","groupid":"1"], ["name": "first element", "foo": "bar","groupid":"1"],["name": "second element", "foo": "bar","groupid":"2"], ["name": "second element", "foo": "bar","groupid":"2"]]

in dictionary have key groupid.

is possible can dictionary data groupid = %@?

i want filter data based on grouping

suppose have 4 data, , group id same in 2 data. want delete data groupid same dictionary.

if groupid == 1 data deleted dictionary groupid == 1 , tableview reload data.

i doing because want delete group data.

you can use filter on array remove dictionaries array, check example

var subitems: [[string:string]] = [     ["groupid": "1", "b": "2"],     ["groupid": "3", "b": "4"],     ["groupid": "1", "b": "6"] ]  var filteredsubitems = subitems.filter{     $0["groupid"] != "1" // change groupid }  print(filteredsubitems)
