Eyüpsultan Municipality decided to use an open source operating system in desktop computers in 2015.
The most important goal of the project was to ensure information security and reduce foreign dependency.
As a result of the research and analyzes prepared, a detailed migration plan was prepared.
As a first step, licensed office software installed on all computers has been removed. LibreOffice software was installed instead.
Later, LibreOffice training was given to the municipal staff.
Meanwhile, preparations were made for the operating system migration.
Instead of the existing licensed operating system, Turkey's developed Pardus GNU / Linux distribution was decided to use.
Applications on the Pardus GNU / linux operating system were examined in detail and unnecessary applications were removed.
And a new ISO file was created with the applications used in Eyüpsultan municipality.
This process automated the setup steps and reduced setup time.
While the project continued at full speed, the staff were again trained on LibreOffice and Pardus GNU / linux.
After their training, the users took...
RealityKit was a new framework introduced in 2019 to implement high-performance 3D simulation and rendering. We’ve explored ARKit development for 3D objects using SceneKit. In this tutorial, we will see how to build an interactive 3D AR app using RealityKit and Reality Composer, which was released alongside with RealityKit. With Reality Composer, Apple is taking AR app development a step further, making it simpler for beginners to create an interactive AR experience without writing a line of code. You will understand what I mean after going through this tutorial. Designing the AR Scene We’ll start with Reality Composer to create […]
SwiftUI has made it very easy for developers to create a list view, similar to a table view in UIKit. When working with table view in UIKit, you can easily configure a cell’s indicator by setting the accessoryType property. For example, to disable the disclosure indicator, you set the property to .none like this: In SwiftUI, it seems Apple doesn’t offer an API to configure the disclosure indicator in the list view. In this short tutorial, I will show you a workaround to hide disclosure indicators if you need to. Let’s begin with a simple list view: If you run […]
ScrollViewReader is one of my favorite new features in the new version of SwiftUI. Before the release of iOS 14, it’s not easy to control the scrolling position of the built-in ScrollView. If you want the scroll view to scroll to a particular location, you have to figure out your own solution. With ScrollViewReader, you can programmatically make the scroll view to scroll to a specific location with just a few lines of code. In this tutorial, we will look into this new view component and see how you can apply it to your app. Creating a Horizontal ScrollView To […]
Welcome to a new tutorial, where we are going to discuss about two quite interesting, related and interconnected concepts; how to scan images and perform text recognition on them. It might sound like a complicated task, but soon you will find out that this is far from being true. Thanks to Vision framework, performing text scanning and recognition is nowadays a quite straightforward job. Let’s see briefly a few details regarding both tasks. In order to scan images with a device, VisionKit framework provides a specific class called VNDocumentCameraViewController for that purpose. It’s a UIKit view controller that allows to […]
When the SwiftUI framework was first released, developers are required to wrap the MKMapView class in order to embed a map in a SwiftUI application. With the release of Xcode 12, the latest version of SwiftUI provides a native SwiftUI Map view for you to display a map interface . Optionally, you can display annotations using the built-in annotation views such as MapMarker. In this tutorial, I will show you how to use the Map structure in SwiftUI and create annotations at a specific locations on the map. Displaying a Map View in SwiftUI By referring the documentation of Map, […]

Importing photos and videos as media items is one of the most common features that the majority of iOS applications include. In general lines, there are two ways to do that; either by using a system-provided controller, or by implementing a custom picker manually. Obviously, going with the second approach is a much harder and complicated process. In this post we are going to focus on the first option, and particularly on a brand new photo picker controller that was first introduced in iOS 14. That is the PHPicker API! Let’s take a look at a few interesting and useful […]
If you have some experience with iOS app development, you should be very familiar with the data source protocols such as UICollectionViewDataSource and UITableViewDataSource. Traditionally, to populate data in a collection view, you have to adopt the UICollectionViewDataSource protocol and implement two required methods: func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell Since the release of iOS 13, Apple introduced a new approach known as Diffable Data Sources to manage data for a collection view. This approach replaces the old approach which uses the UICollectionViewDataSource protocol. You no longer need […]
In the earlier tutorial, we showed you how to work with TabView to display a tab bar interface. In iOS 14, Apple introduced a new style called PageTabViewStyle in the SwiftUI framework for developers to create paged scrolling interface. In this tutorial, we will show you how to implement his type of tab view style. Let’s begin with a simple tab view. Assuming you’ve created a SwiftUI project, you can replace the ContentView struct like this: When you run the app in the preview canvas, this gives you a tab view with 5 tab items. Creating a Paged Scrolling View […]
For experienced developers, you probably have used the Core Graphics APIs to draw shapes and objects. It’s a very powerful framework for you to create vector-based drawings. SwiftUI also provides several vector drawing APIs for developers to draw lines and shapes. In this tutorial, you will learn how to draw lines, arcs, and pie charts using Path and the built-in Shape such as Circle and RoundedRectangle. Here are the topics we’ll cover: Understanding Path and how to draw a line How to draw curve How to draw a pie chart Note: This is a excerpt of our Mastering SwiftUI book. […]
We are launching an iOS 14 update for our flagship iOS programming course – Beginning iOS 14 Programming with Swift. The course has been fully updated for iOS 14, Swift 5.3, and Xcode 12. The beginner book is still written for beginners who want to grasp the iOS development skills and train yourself to become a profession iOS developer. We have reviewed all the source code and re-captured all screenshots to support Xcode 12. The demo app is also fully updated for iPhone 12 and iPad Pro, plus it now supports dark mode. On top of all that, we will […]
In WWDC 2019, Apple announced a brand new feature for Xcode 11; the capability to create a new kind of binary frameworks with a special format called XCFramework. That was fantastic news to anyone, since an ongoing inconvenient situation that was lasting for years finally came to its end. Up until then, a binary framework could be used in one target platform only, and for a specific family of devices. For example, it was officially impossible to build a framework that would contain code aiming on both real iOS devices and the Simulator; unofficial solutions had come up of course […]
The tab bar interface appears in some of the most popular mobile apps such as Facebook, Instagram, and Twitter. A tab bar appears at the bottom of an app screen and let users quickly switch between different functions of an app. In UIKit, you use the UITabBarController to create the tab bar interface. For the SwiftUI framework, it provides a UI component called TabView for developers to display tabs in the apps. In this tutorial, we will show you how to create a tab bar interface using TabView, handle the tab selection, and customize the appearance of the tab bar. […]
We are launching the update of our Mastering SwiftUI book for Xcode 12 and iOS 14. Along with the release of Xcode 12, Apple released a big update to the SwiftUI framework with a lot of additions. Other than adding new UI components to streamline your UI development, Xcode 12 introduces a new App lifecycle API for SwiftUI. There are no more AppDelegate and SceneDelegate in the project. In other words, you can build a pure SwiftUI-based on iOS 14. All the content and projects of our Mastering SwiftUI book are updated to use this new lifecycle. You will learn […]
