How Xcode Works & Architecture?

Xcode is an integrated development environment (IDE) developed by Apple Inc. for macOS. It provides tools for developing software for macOS, iOS, watchOS, tvOS, and Linux. Xcode is built on top of the LLVM compiler infrastructure and uses Objective-C, Swift, and C programming languages. It also includes a variety of other tools, such as a debugger, a GUI designer, and a simulator. The architecture of Xcode is designed to be modular and extensible. This means that it is easy to add new features and functionality to Xcode without having to change the core of the IDE.

The modular architecture of Xcode also makes it easier to debug and troubleshoot problems. If a problem occurs in one module of Xcode, it is usually possible to isolate the problem to that module and fix it without affecting the other modules. The extensible architecture of Xcode makes it a popular platform for developers. Developers can create new extensions for Xcode that add new features and functionality.

Here are some of the key components of the Xcode architecture:

• The Xcode project: The Xcode project is a file that contains information about your app. It includes the name of your app, the target platforms, and the source code for your app.
• The Xcode debugger: The Xcode debugger is a powerful tool that allows you to step through your code line by line, inspect variables, and set breakpoints. This makes it easy to debug your code.
• The Xcode GUI designer: The Xcode GUI designer is a powerful tool that allows you to create macOS and iOS apps with ease. You can use the GUI designer to create windows, buttons, text fields, and other GUI elements.
• The Xcode simulator: The Xcode simulator allows you to test your apps on virtual devices. This is a great way to test your apps before you deploy them to real devices.
• The Xcode build system: The Xcode build system is responsible for compiling your code and creating the final executable file for your app.

The Australian Institute of ICT (AIICT) has introduced a new ‘Certified Artificial Intelligence Professional’course, jointly developed with Amazon Web Services (AWS)for aspiring Artificial Intelligence (AI) developers and Machine Learning (ML) professionals.

The course enables novice practitioners who are interested in entering the field of AI to become job-ready engineers in just six months. There will be a skill assessment to evaluate the student’s current skills and experience, but the only prerequisites are a basic understanding of mathematics and statistics and, or alternatively, relevant experience in the industry, such as an internship.

According to the 2020 IT Skills and Salary Report, ‘AI, cognitive computing and machine learning’ was reported as the second weakest IT skillset in organisations across the world, presenting serious hiring challenges for IT managers.[1] The lack of skilled AI professionals forms part of a broader technology skills shortage in Australia, with new research commissioned by AWS revealing that Australia will require an additional 6.5 million newly-skilled and reskilled digital workers by 2026 to meet future demand for technology skills (79 per cent more than Australia currently has).

Jon Lang, CEO of AIICT said, “We’re seeing a severe shortage of skilled AI professionals and in many instances, organisations are simply unable to fill these roles. With AI and ML becoming a critical part of the digital transformation process for many organisations, the demand is on the rise for engineers with these specific skills across a wide range of industries.”

“At AIICT, we are committed to providing all our students with the most contemporary, relevant and future-focused skills. Together with AWS we hope to address the skyrocketing demand in the AI field and support those looking to start their career as an AI engineer,” added Lang.

An ‘Artificial Intelligence Specialist’ is currently the top emerging job role in both Australia and the United States, according to the LinkedIn 2020 Report, with hiring growth surging 74% annually in the last four years.[2]

Moreover, as of January 2021, the average salary for a Machine Learning Engineer in Australia is estimated at $94,255 ($1,812 weekly), according to Indeed.[3] This is 34% above the average annual earnings for all employees in Australia, which is $66,575 ($1,280 weekly), according to the ABS[4].

“There have been rapid technological advances in cloud computing, machine learning and artificial intelligence, however we still face an ongoing skills shortage in these areas,” said Melanie Botha, Head of Training and Certification, Australia and New Zealand. “AWS is passionate about continual education, and the need to build new digital skills to drive economic growth and job creation in Australia and New Zealand. Together with AIICT, we want to close the digital skills gap, equip individuals with job-ready skills that will boost their employability, and support the upskilling of our nation.”

AIICT is a start-up launched in 2019 by DDLS, one of Australia’s largest providers of corporate IT and cybersecurity training, and is one of only two authorised AWS Training Partners in the country.

The Certified Artificial Intelligence Professional course prepares individuals for a role as an entry-level AI developer or Machine Learning Engineer. Through its unique Industry Partner Program, AIICT connects recent graduates with leading employers to help them secure a front-line role, while simultaneously tackling skills shortages in the field.

The course incorporates three globally recognised AWS certifications, including AWS Certified Cloud Practitioner, AWS Certified Data Analytics and AWS Certified Machine Learning, as well as the TensorFlow Developer Certificate.

The hands-on course places a high focus on the development of real-world skills, and provides students access to unique ‘live labs’, which enable them to practice developing and deploying machine learning models in a simulated work environment.

The course platform also includes video content, quizzes, expert led webinars and direct access to online mentorship from industry experts, who are on hand to guide students through the course material.

AIICT operates using a unique self-paced course schedule, which is not bound by the traditional academic structures of terms and semesters. The flexible learning options allow students to build an online learning schedule around their life and encourages people who may not have considered a career in AI as an option previously, to undertake training.

The AIICT platform also allows students to join a community of like-minded individuals for communication and collaboration as they progress through the course.

Some of the course’s key learning outcomes include:

Understanding the fundamentals of AI/ML processes and concepts, and elements of data science.
Learning the key concepts of cloud computing with a deep dive into AWS.
Gaining skills in Python, SQL JavaScript, and Deep Learning.
Learning how to build scalable AI-powered algorithms with TensorFlow.
