ios - Filter an array based on empty value in Swift -


i trying filter array of dictionaries. below code sample of scenario looking for

let names = [      [ "firstname":"chris","middlename":"alex"],     ["firstname":"matt","middlename":""],     ["firstname":"john","middlename":"luke"],     ["firstname":"mary","middlename":"john"], ]

the final result should array whom there middle name.

this did trick

names.filter {   if let middlename = $0["middlename"] {     return !middlename.isempty   }   return false }
