ios - Check if an element is present in 3D array Swift -

i have array gets instantiated in viewdidload var bookingsarray : [[string]] = []

i adding elements in way:

var configuration: [string] = []             configuration.append(textfieldfacility.text!)             configuration.append((pickslottf.text?.components(separatedby: " ")[0])!)             configuration.append((pickslottf.text?.components(separatedby: " ")[1])!)             bookingsarray.append(configuration [string]) 

bookingsarray looks :

[["a", "20-08-2017", "14:00"], ["b", "20-08-2017", "14:00"]] 

while adding new elements bookingsarray, want check if new element present in array. how do in case of multi-dimensional array?

first of all, if want unique objects use set.

if not possible highly recommend use custom struct can conform equatable rather nested array , example

struct booking : equatable {     let facilty : string     let date : string     let time : string      static func ==(lhs : booking, rhs : booking) -> bool {         return lhs.facilty == rhs.facilty && lhs.date == rhs.date && lhs.time == rhs.time     } } 

then declare array as

var bookingsarray = [booking]() 

and create object

let datearray = pickslottf.text!.components(separatedby: " ") let configuration = booking(facility: textfieldfacility.text!,                             date: datearray[0],                             time = datearray[1]) bookingsarray.append(configuration) 

the huge benefit can check

if bookingsarray.contains(item)
