ios - What's the best way to store 2 x n Strings in Swift? -

i store different count of string data pairs in format:

string a[n][2]{  {"1","2"}, {"3","4"}, {"5","6"} {... }}; 

i add new pair using append methode or similar... possible , nice handle 2d array or should use dictionaire?? , how implement that? thanks!

you potentially use array of tuples solve this:

typealias stringpair = (string, string)  var mystrings = [stringpair]()  mystrings.append(stringpair("1", "2")) 

edit: search string pair, do:

var doesitcontain1 = mystrings.contains {     $0.0 == "1" } 

you change type alias use names:

typealias stringpair = (string1: string, string2: string) 

and filter with:

var doesitcontain1 = mystrings.contains {     $0.string1 == "1" } 

edit 2: sort:

var sorted = mystrings.sort {     return $0.string1 < $1.string1 }
