1)NavigationController(Object Libery)
2)Change Entry point viewcontroller to navigation controller
3)Drag button and add to top of the tableview navigation (middle one)
4)create segue to tableview to viewcontroller(select show)
5)add labels(in tableview)(show details)
6)in viewcontroller add label and textfield (to add details)
7)craete file NoteCell.swift(this file contain the label name in tableview)
8)craete file NoteTableView.swift(this file contain all tableview function operation)
9)Change the viewController name to NoteDetailVC.swift
10)In StoryBoard Change all classname
i)viewcontroller -> NoteDetailVC
ii)Middle Navigation change to ->NoteTableview
iii)inside of that change Tableviewcell to -> NoteCell

11)add button on viewcontroller (NoteDetailVC) in add Savebutton


add Entity
1)Note
i)id - Integer32
ii)title -String
iii)desc-String
iv)deleteddate-Date

12)in coredata open left panel to change codegen -> Manual/None

13)Create Note.swift file to add all attribute in that

3)Collection View(images and text)

-Add all images in Assert.xcasserts(1x)
-collection view (object Libery)
-select collectionview press ctrl drag to viewcontroller and set Datasource,delegate
-inside Collectionview ->select collectionview cell
-object libery drag and drop Image,text filed
-change name Collectionview cell to -> cell (Identifier name change)
-craete file (cocoa Touch class) name->CollectionViewCell subclass UiCollectionViewCell
-set that class file to cell ->chnage class to MycollectionViewCell
-open viewcontroller(assist)
-select Collection view to ctrl and drag to view controller to create Outlet
