• error when trying save image in nsuserdefaults using swift 3 answers

hi i'm trying storing array of images using swift not working

i use saving

     let defaults = nsuserdefaults.standarduserdefaults()     defaults.setobject(photos, forkey: header)     defaults.synchronize() 

and loading

if let items = defaults.arrayforkey(header) {     self.photos = self.photos + items   } 

if photos array of uiimage, code nothing:

 defaults.setobject(photos...) 

the reason uiimage not property list type. defaults property list. see apple's docs:
