Swift : Convert string array to array example



Tags : swift convert-array string-array stringByTrimmingCharactersInSet

Problem :

You have a string array and you want to convert it to array. How to do that?

Solution :

First, remove the [ and ] from the string with stringByTrimmingCharactersInSet() function. Then, split it to an array by commas and finally remove the white spaces.

For example:

 let array = [1,2,3,4];
 let stringArray = array.description; 

 let result = stringArray
 .stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "[]"))
 .componentsSeparatedByString(",")
 .map { return $0.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet()) }

Hope this helps!
