Code Structure - Swift

so i'm building pretty basic sheet music editor in swift. i'm using coredata store , update songs. add, delete , update methods change both data in songs array , add stuff coredata model. i'm wondering if dumb way structure code. should bypass songs array , interact core data directly?

code:

 class datastore {      var songs: array<song> = [song]()       init() { songs = loadsongsfromcoredata() }       func addsong(song: song) { ... }      func deletesongatindex(index: int) { ... }      func updatesongatindex(song: song, index: int) { ... }       func loadsongsfromcoredata() -> array<song> { ... }  }
