After basic settings we set UINavigationBar colors and clear background image, and set our own separator line with an image. After that, we create Navigation Bar UIBarButtonItems programmatically and set their color too. Finally, we show and hide UINavigationBar at switching between ViewControllers, and hide StatusBar. These are very useful things, which can be present nice solutions. 

 This is a Swift 2.2 version of previous ObjC tutorial. Sometimes it's very useful to check, which UIFonts are already available, and which should be imported. In this little tutorial, I will show, how can you import your own custom UIFont, and how can you check the available UIFonts and Families in your Xcode Project. IOS 9.3 Xcode 7.3 Swift 2.2

Our goal to save User Entity’s Name (userName-string) and the type of the user, so the Type Entity’s Name (typeName-string), and FetchRequest in UITableViewController the user name and the type Relationship’s Name attribute.

Sometimes it's very useful to check, which UIFonts are already available, and which should be imported. In this little tutorial, I will show, how can you import your own custom Font, and how can you check the available fonts in your Xcode Project.  IOS 9.3 Xcode 7.3

When you need to change your Core Data Entities or structure, you have to add new model version before you send your App in AppStore. If you change just attributes or fetched templates, it’s not needed, you can do it without consequence. But if you want to add a new Entity, you have to migrate your persistent store to a new model version. You should also set mappings for the migration. In this tutorial, we add model versions, model mappings, and using Lightweight Migration.

In this Xcode 6 and IOS 8 UITextField Animation tutorial, we create a fade in & out animation, and with 2 UITextField we create dimming and lighting CABasicAnimation when the Textfield become FirstResponder, and when the user end editing. It could be very useful if you would like to create a nice interface animation for a basic form. 

 In this tutorial, we edit user data and delete attributes. We save the modified NSManagedObject's attributes in Core Data, and we delete the objects too at the appropriate NSManagedObjectContext. 

In this tutorial, we continue the segue settings. Now we do custom segue with UIAnimation. This tutorial made in IOS 8 Xcode 6 Tutorial: Basic Xcode project. In the first part, we created UIViewControllers, with UIButtons. Embed UINavigationController, and manage Custom Segue and UnWind Segue. Part 2/2 Tutorial, using UIAnimation at Custom Segue.

In this Xcode 6, IOS 8 Core Data Tutorial, we create first of all the ManagedObjectModel. First we create a SingleView Xcode project, and set the Core Data, Entities and Relationships. Finally we set the delete rules too.

 With Core Data framework you can manage your objects in your App. You can manage your object’s life-cycle and object graph, so the attributes and relationships of your entities. You can edit, save modify and rebuild your database. You can group, filtering, organizing your data. I try to explain just the basics with this example.
