How to get started SwiftUI interview preparation

To get started, it’s important to familiarize yourself with the basics of SwiftUI. This includes understanding the core concepts such as views, modifiers, and binding.

SwiftUI Interview Questions & Answers

Note

The last year 2022, I wrote a series of articles about iOS interview questions and answers. My plan for the next couple of months is to enhance the series Swift iOS interview questions and answers along with a new series for SwiftUI.

Fellow iOS Developers, Please Keep In Mind

  • It’s important to keep in mind a few key points as you prepare for your interview. Firstly, it’s worth noting that there are over 1000 interview questions available in the interview section for you to review and prepare for. While reading the question, take the time to carefully consider your answer and think about the information that you want to convey. The answer provided here in this blog can be explained in a different way. You should also prepare your examples.
  • It’s also important to remember that these interview questions are not meant to be difficult. The interviewer is not looking to challenge you, but rather to start a conversation that will allow your abilities and interests to come to the forefront. They want to get to know you and your experience better.
  • Finally, it’s crucial to avoid simply answering questions with a “yes” or “no.” Interviewers are looking for more in-depth responses that include basic understanding, reasoning, explanation, and examples. So, make an effort to elaborate on your answers and provide specific, relevant information to support your response. This will demonstrate your thoughtfulness and show the interviewer that you are well-prepared for the interview.
