What's the difference between an IOS developer and an IOS engineer?

    In general, the terms "IOS developer" and "IOS engineer" are used interchangeably in the industry to refer to professionals who develop software applications for Apple's iOS operating system. However, some companies may use these terms to differentiate between different levels of expertise or job responsibilities.

 An IOS developer typically refers to someone who is responsible for designing, coding, and testing IOS applications using programming languages such as Swift or Objective-C. They may also be responsible for troubleshooting issues and working with other team members to ensure that the application functions properly. 

On the other hand, an IOS engineer may be a more senior-level professional who is responsible for designing and developing complex IOS applications that require a deep understanding of the underlying operating system and its frameworks. They may also be responsible for leading a team of developers, managing the project timeline, and ensuring that the application meets the company's standards for performance, security, and usability. 

However, it's important to note that the specific job titles and responsibilities may vary between companies, and there may not always be a clear distinction between the roles of an IOS developer and an IOS engineer.
