iOS for Android Developers (with Swift)

Nov 16, 201430 likes11,734 views

As an app developer there is always pressure to understand and be able to address both major platforms. At first blush, coding for iOS seems quite different than for Android, perhaps due to the language differences between Objective-C and Java, and of course there is a different IDE and framework. With the introduction of Swift, this chasm seems much smaller. This talk will map Android and Java functionality to similar concepts in iOS using Swift. We’ll see the similarities and differences, focusing on framework concepts, and migrate a simple Android app to iOS.

This document discusses categories for working C++ programmers. It covers low-level and high-level concepts including composition, objects, arrows between objects, pure functions, side effects, and controlling side effects through composition. The key ideas are representing functions as arrows between objects, composing functions through their results and arguments, and using monads to encapsulate side effects while maintaining function purity.

Debugging and Profiling C++ Template MetaprogramsPlatonov Sergey

Template metaprogramming is an emerging new direction in C++ programming for executing algorithms in compilation time. Despite all of its already proven benefits and numerous successful applications, it is yet to be accepted in industrial projects. One reason is the lack of professional software tools supporting the development of template metaprograms. A strong analogue exists between traditional runtime programs and compile-time metaprograms. This connection presents the possibility for creating development tools similar to those already used when writing runtime programs. This paper introduces Templight, a debugging framework that reveals the steps executed by the compiler during the compilation of C++ programs with templates. Templight’s features include following the instantiation chain, setting breakpoints, and inspecting metaprogram information. This framework aims to take a step forward to help template metaprogramming become more accepted in the software industry.

Objectivec vs swiftNisr Mohamed

Objective-C and Swift are programming languages used to develop apps for Apple platforms. Objective-C was developed in the 1980s and has since been replaced by Swift, which was introduced in 2014. While the two languages share some similarities like curly braces and square brackets, Swift addresses issues with Objective-C like bulky syntax and lack of features like generics through its cleaner syntax and strong typing.

A Journey From Objective C to Swift - ChromeinfotechChromeInfo Technologies

Objective-C programming has changed forever with the introduction of Swift.With the introduction of swift, Lets have a look at journey from objective c which was created at stepstone Comapny in early 1980's to swift announced by apple iOS Application Development will be one more easy with Swift. According to the new research of Gartner, Apple – with more than 1.2 billion units sold worldwide- exponentially increasing the need for iOS Applications Development ; and this opens a huge space for the iOS Application in the wortld of business. Here are some factors why? Swift was released as the replacement for the objective C. As of Swift have lots of advantages over Objective C, Let's Take a look into it 1. Swift support variable declaration by var keyword. It seem familiar to C# developer. There are no more datatype declaration. For examples: var x = 1 and var y = "1" is different. x is a numeric var and y is string var. So you don't have to assign it for specified datatype. It understand what your mean. 2. Swift support Optionals. An Optional var could be assigned with value or nil. And Many More.......#ChromeInfotech

The document contains multiple choice questions about JavaScript concepts like operators, functions, objects, and methods. Some key points covered are: - Void is an operator, not a method, function, or statement. - Anonymous functions can be used to process data before passing to another function, decrease number of functions used in code, and define variable scope. - Advantages of JavaScript include ability to reuse code, apply changes across classes/objects, and create user-defined interfaces. - The eval() method is used to evaluate regular expressions, not evaluate() or evalu().

Нарушение DRY принципа особенно часто возникает в микросервисах. Чтобы избежать этой проблемы, вы можете использовать повторно используемые компоненты, например, приватные пакеты npm. Лучшие практики, которые помогут вам достичь этого включают в себя паттерн ECB для организации кода, манифест 12-ти факторного приложения, использование генерации кода. В нашем проекте мы используем технический стек на основе Node.js, Docker, RabbitMQ, но идеи из этого доклада могут быть использованы для любого технического стека микросервисов

Polymorphism (2)Army Public School and College -Faisal

This document discusses polymorphism in C# through method overloading and overriding. It shows how to create a base DrawingObject class that can be inherited by Line, Circle, and Square classes, where each subclass overrides the Draw method to output its type. The Main method creates instances of each subclass and calls their Draw methods to demonstrate polymorphism. The document also compares abstract classes and interfaces, noting that abstract classes can contain implemented methods while interfaces only contain signatures, and interfaces allow multiple inheritance while abstract classes do not.

Constructor and destructor in c++Learn By Watch

This document discusses constructors and destructors in C++. It explains that constructors are special functions called when an object is created that have the same name as the class, cannot return a value, and are used to initialize objects. Destructors are also special functions with the same name as the class but with a ~ sign that cannot return a value and are called when an object is destroyed to cleanup resources. The document aims to help readers understand when and how constructors and destructors are used.

JSHint: Learning JavaScript the Hard WayAdrian-Tudor Panescu

If you want to learn JavaScript nowadays, you will normally go to W3Schools, MDN, or Codecademy, start with a simple "helloWorld()" tutorial and build up from there. Here is an alternative to this method of learning the intricacies of an otherwise cool language: take a junior programmer coming from the Java/ Python/ C++ world, give him an existing NodeJS/ MongoDB/ Redis/ Web Sockets/ single-page HTML5 Web application, and one month to add new major features to it. Our junior does not know JavaScript, but is in love with static analysis/ linting tools, and thinks of using JSLint in order to both learn the language and complete his tasks in time with a minimal number of bugs. As this is the way in which I learned JavaScript, I will present you my experience, including the fact that the programmers before me had little idea of how the language actually works, what lessons I was (self-)taught in the process, and how this knowledge and some practices stuck with me. While this was an unconventional learning experience, I believe that the method can be quite efficient, maybe not for first-year Computer Science students, but for programmers coming from other language realms.

#OOP_D_ITS - 4th - C++ Oop And Class StructureHadziq Fabroyir

1. C++ classes represent groups of similar instances, with fields that define each instance and methods that operate on instances. 2. The document discusses class access modifiers like public and private, and how they control access to class fields and methods. It also covers class methods like accessors, mutators, and static fields. 3. Class constructors and destructors allow initialization and cleanup of class instances, running automatically when instances are created and destroyed.

Essential Test-Driven DevelopmentTechWell

Test-driven development (TDD) is a powerful technique for combining software design, unit testing, and coding in a continuous process to increase reliability and produce better code design. Using the TDD approach, developers write programs in very short development cycles: first the developer writes a failing automated test case that defines a new function or improvement, then produces code to pass that test, and finally refactors the new code to acceptable standards. The developer repeats this process many times until the behavior is complete and fully tested. Rob Myers demonstrates the essential TDD techniques, including unit testing with the common xUnit family of open source development frameworks, refactoring as just-in-time design, plus Fake It, Triangulate, and Obvious Implementation. During this hands-on session, you’ll use exercises to practice the techniques. With many years of product development experience using TDD, Rob will address the questions that arise during your own relaxed exploration of test-driven development.

Cross Platform App Development with C++Joan Puig Sanz

After reimplement many features several times in different platforms is time to think that it should be a better way. There are many frameworks that allows the developers to write the code once and deploy it "everywhere", but the final result is an app with a non native look and feel or with an emulated look and feel that the users can see and rate according to the quality. There are other ways to develop apps for multiple platforms without rewriting the same code over and over. I'll talk about one of that ways which consists on developing the core with C++ and implement the UI natively. This method could sound very scary because of the C++ reputation (memory leaks, the standard library, etc), but with C++11 all this has been improved in a very sweet way, so maybe it is time to take an other look at this language and see how can we take advantage of it.

Bust the Android Fragmentation MythChiu-Ki Chan

Designers and developers have been afraid of the variety of Android flavors for way too long. Android borrows a lot of concept from the web, and we can use the same techniques to cater to the different OS versions and form factors. Be responsive. Forget about absolute coordinates. Embrace the relative, use resource folders to differentiate among screen sizes, much like CSS media queries. Be progressive. Take advantage of the latest Android functionalities, but gracefully fall back to the basics when you are on older OS versions. Remember the days when not all browsers have javascript?

Swift on the Server Dev_Events

Robert Dickerson, Software Developer, IBM-Swift, @rfdickerson Of course its allowed - just matters how you do it. In this part of the workshop we’ll start with serverless: New cloud programming models enabled by serverless architectures are emerging, allowing developers to focus more sharply on creating their applications and less on managing their infrastructure. The OpenWhisk project started by IBM and now part of Apache provides an open source platform to enable these cloud native, event-driven applications. In this talk, we will provide an overview of serverless architectures, introduce the OpenWhisk programming model, and then show how to deploy an OpenWhisk application on IBM Bluemix OpenWhisk. Then we’ll get Swift! It’s not only a language you turn to to build your iOS application, but it can also be the language you can use to build your backend. This part of the workshop will use a text-based adventure game called "GameOn" as an example for building a Server-side Swift App. Topics include: • How to create a web service using the IBM Kitura web framework • How to integrate the Watson SDK for Swift into your application • How to dockerize your Swift application and deploy it to Bluemix

SwiftLarry Ball

Swift is a new programming language created by Apple as an alternative to Objective-C for iOS development. It is faster, safer, and has a cleaner syntax than Objective-C. To start developing iOS apps in Swift, developers need a Mac computer, Xcode installed, and an Apple Developer account. Key aspects of iOS app development in Swift covered in the document include prototyping apps, using Xcode, optionals and auto layout, implementing protocols like UITableViewDelegate, and using MVC architecture.

class vs structDaniel Souza

This document discusses the differences between classes and structs in Swift. Structs provide value semantics instead of reference semantics, meaning they are passed by value rather than by reference. Structs are beneficial because they are immutable by default, have member-wise initialization, and are passed by value. Classes should be used for modeling real-world objects that have inheritance and behaviors, while structs are better suited for simple model types that represent values. The conclusion recommends trying to use structs beyond just models and evolving with Swift.

Struct vs Class in SwiftUngur Laurentiu Nicolae

Structs are preferable to classes in Swift for several reasons: 1. Structs are value types, so copies have independent state, while classes are reference types where copies share the same state. 2. Structs provide value semantics, automatic initializers, and are much faster than classes due to being passed by value rather than reference. 3. As a rule of thumb, use structs when encapsulating simple data or when copies should have independent state, while classes should be used for shared, mutable state or complex frameworks.

Introduction to Software DevelopmentZeeshan MIrza

Software development has shifted focus from efficiency to productivity, reusability, and user-friendliness. Object-oriented programming (OOP) models objects that contain data and methods. Key OOP concepts include inheritance, where subclasses extend and modify superclass features. An integrated development environment (IDE) combines tools like editors, compilers, linkers, and debuggers. Java uses a hybrid approach of compiling to bytecode, then interpreting for platform independence. Console applications use text input/output. Graphical user interface (GUI) applications use menus and buttons. Applets run in web browsers.

The document discusses various topics related to Android testing including: - Best practice is to create a separate test project rather than including tests in the main project. This keeps tests stripped out of the main code and easier/faster to run. - Tests can be run from Eclipse or from the command line with options to run all tests, a single test class/method, or filter by category. - The Android SDK tools, emulator/AVD, and tools like uiautomatorviewer and uiautomator are needed to perform UI tests. - Different types of tests include unit tests, integration tests to check components work together, acceptance tests for QA, and performance tests to check system behavior.

This document provides an overview of C++ programming concepts including: - Procedure-oriented programming focuses on tasks like reading, calculating and printing using functions, while object-oriented programming emphasizes data through objects and classes. - C++ was developed to include object-oriented features while retaining C's simplicity, with classes, inheritance, and other features enabling abstract data types. - Key concepts covered include classes, objects, member functions, inline functions, passing objects as parameters, returning objects, arrays of objects, and function overloading. Examples are provided to illustrate each concept.

Refactor your way forwardJorge Ortiz

The first question after people have learned about how to implement anadvanced architecture in their applications from scratch is: "How do I transform my codebase from its current state to a well architected app?" Forget about BigBang rewrites. Come and learn some strategies, tricks, and gotchas about how to do the migration to an advanced arch mobile app. Move to from Objective-C to Swift in the process and keep it functional during the whole process.

Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora

Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak

As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.

Not So Common Memory Leaks in Java WebinarTier1 app

This SlideShare presentation is from our May webinar, “Not So Common Memory Leaks & How to Fix Them?”, where we explored lesser-known memory leak patterns in Java applications. Unlike typical leaks, subtle issues such as thread local misuse, inner class references, uncached collections, and misbehaving frameworks often go undetected and gradually degrade performance. This deck provides in-depth insights into identifying these hidden leaks using advanced heap analysis and profiling techniques, along with real-world case studies and practical solutions. Ideal for developers and performance engineers aiming to deepen their understanding of Java memory management and improve application stability.
