Hi there!
I have decided to switch my focus from optimizing and promoting websites and online stores to iOS development. While I have a basic understanding of programming theory, I am approaching this as a professional development opportunity and a chance to work on interesting personal projects.

Here are a few questions I have:
1. How urgently do I need to invest in a MacBook for iOS development? While I know it will eventually be necessary, I'm hesitant to spend the money upfront without having much knowledge on the topic. Would it be feasible to use an emulator on Windows 7 for the first few months until I understand the basics?
2. What kind of MacBook do I need for iOS development? Would a MacBook Air 13" with Intel Core i5 and 4 GB memory suffice, or should I consider something more powerful like a MacBook Pro 13" Retina with Intel Core i5 and 8 GB memory?
3. Is it necessary to purchase an iOS device for development training, or can I use an emulator on Windows 7/OS X? If it is necessary, should I purchase a newer device like the iPhone 5/5s or an older one like the 4s?
4. Is it beneficial to take classical courses in Objective-C, or can I figure it out on my own? Should I take monthly courses to establish a base, or can I start learning at home independently?
5. How should I plan my self-learning process for iOS development? Should I read, try, and consult as needed, or is there a specific system to follow for raising my level of expertise?
If anyone would be willing to answer my questions and provide brief consultations a couple times a week, please let me know in the comments. Thank you for your interest and attention.
To start developing for Apple, you need an Apple computer - no virtual machines or other alternatives. For beginners, any Mac device will do, including a MacBook, Mac mini, or iMac. It's best to go for a 13-inch MacBook Pro without Retina with minimum configuration, as it can be easily upgraded. Emulators work well for basic functions, so actual devices aren't necessary at first. A developer license is needed for running an application on a real device, costing $100 per year.
It's essential to study Object-Oriented Programming (OOP) theory first, including classes, objects, pointers, and constructors. Objective C books are great resources to start with, and it's recommended to read them thoroughly before moving on to instructional videos. After absorbing the basics and gaining some understanding, taking courses can help systematize knowledge, although it's not advisable to start from zero. Any information needs to be digested, thought over, and understood before progressing, as courses without preparation are often ineffective and a waste of money.
You can opt for a native MacBook or Mac Mini, depending on your budget. A more expensive device will likely provide greater comfort and efficiency, and the Retina 13" is an excellent option for a balance between portability and power. While not necessary at the beginning, it's possible to purchase a minimal iPad mini with Retina if desired.
With the introduction of Swift, it's advisable to start learning this rather complex language, which is relatively new compared to others. Useful resources for learning include Code School and Apple splints available in iBooks. Additionally, there are online Skype conferences on profile sites that can offer support and guidance.
A MAC OS computer, such as a MacBook or Mac Mini, is essential for development purposes. While an iOS device can be helpful, it's more of a secondary tool since simulators can be utilized initially.
For testing on an actual device, a developer certificate is required. It's important to keep in mind that testing on the latest device won't necessarily provide an accurate representation of how the app will perform on older devices. Opting to test on a 4S initially can help ensure everything runs smoothly across different devices. However, purchasing an older device may prove problematic in the future as APPLE will eventually discontinue updates, which could limit functionality for developers.
iOS developer must have knowledge of programming.

Developers need to have a solid understanding of certain fundamental topics, including algorithms and data structures, OOP, SOLID design principles, databases, and ways to organize network interactions. It's also important to understand computer architectures, software development methodologies, and various architectural approaches in software development.
When it comes to programming languages, Swift is a must-know for iOS developers, while Objective-C familiarity can be advantageous. Familiarity with UIKit, Foundation, CoreAnimation, GCD, and NSOperation frameworks are necessary, as are third-party libraries such as Moya, Alamofire, RxSwift, RxCocoa, and Realm. Understanding Xcode functionality and auxiliary tools such as Fastlane and Xcode Instruments is also important.
Developers should have basic UI/UX design skills and at least a minimum level of English proficiency, as most up-to-date dоcumentation and resources are in English. As experience grows, knowledge of tools such as SPM, CocoaPods, Carthage, Core Data, Push Notifications, and App Store publication will become necessary.
Soft skills are also crucial in a team environment, as well as patience and the ability to persevere through routine tasks. Additionally, the ability to effectively learn and stay current with developing technologies is essential for success in the field.
I can provide detailed guidance on your transition to this new focus.
1. Investing in a MacBook for iOS development is essential, as the Xcode development environment is only available on macOS. While it's possible to use an emulator on Windows for basic testing, it's not a substitute for the full development experience. If you're hesitant about the upfront cost, consider purchasing a refurbished or second-hand MacBook to start with.
2. For iOS development, a MacBook with at least 8 GB of memory is recommended, and a MacBook Pro would offer more power for running resource-intensive tasks such as code compilation and testing on simulators or physical devices.
3. It's highly recommended to have a physical iOS device for testing purposes due to differences between emulators and real hardware. Consider purchasing a used iPhone that supports the latest iOS version to ensure compatibility with your development efforts.
4. While it's possible to learn Objective-C on your own, taking classical courses can provide structured learning and a deeper understanding of the language and its best practices. Additionally, considering that Swift has become the primary language for iOS development, focusing on learning Swift would be beneficial. Online courses and tutorials can also be valuable resources.
5. To plan your self-learning process, start by understanding the basics of Xcode, the iOS SDK, and the Swift programming language. Practice by building small projects and gradually increase the complexity of your applications. Utilize resources like Apple's official dоcumentation, online tutorials, and communities like Stack Overflow for problem-solving. Consistent practice, experimentation, and seeking help when needed are essential for raising your expertise level.
