ios - Map core data row from one table (entity) to an array of [CLLocation]? -

in ios app using core data , need save in table array of "regions" json.

the model "region" object quite simple:

class region : nsobject, nscoding {  ...  //mark: - //mark: - properties  fileprivate var id: string fileprivate var name: string fileprivate var boundarypoints: [cllocation] fileprivate var midcoordinate: cllocationcoordinate2d {     return getpolygonfromboundarypoints().coordinate }  init(id: string, name: string, boundarypoints: [cllocation]) {      self.id = id     self.name = name     self.boundarypoints = boundarypoints      super.init() }   //mark: - //mark: - nscoding  ...  //mark: - //mark: - getters , setters  ...  } 

the problem need persist in table record this:

regions table:

id | title | [cllocation]

what best solution mapping row array of (lat,lng) points ( in case [cllocation]) when storing information "region" object ? "region" object model contains array of boundary points.

in words how should go saving object model has array property sql using core data ? (interested in tables' structure , relationships)

you need store value in core data transformable , use value transformer. can find tutorial more details here: http://lextech.com/2013/01/core-data-transformable-attributes/
