ios - Swift 3 Instance member type -

i have func savenotes() sub-class of nsobject

note.swift file

func savenotes() {         var adictionaries:[nsdictionary] = []         i:int in 0 ..< allnotes.count {             adictionaries.append(allnotes[i].dictionary())         }         userdefaults.standard.set(adictionaries, forkey: kallnotes)     } 

when try run project error "instance member 'savenotes' cannot used on type 'note'; did mean use value of type instead.

code masterviewcontroler.swift

import uikit  import foundation   class masterviewcontroller: uitableviewcontroller {      var objects = nsmutablearray()      override func viewdidload() {         note.loadnotes()         print("allnotes: \(allnotes)")         var n:note = note()         note.savenotes() 

not sure i'm doing wrong here. help.

the error of:

instance member 'savenotes' cannot used on type 'note'; did mean use value of type instead.

is shown compiler because trying call non-instance method directly class.

thus, have 2 approaches:

first: use declared n instance call savenotes() function:

note.loadnotes() print("allnotes: \(allnotes)") let n:note = note() n.savenotes() 

second: if aiming call savenotes() directly note class, should declared static method:

static func savenotes() { ... } 

for more information, check swift documentation - method ("type methods" section).
