A bit of context:
I have experience in C/C++ development (mainly on the "old" C++03) in a Linux-based embedded environment in telecom equipment, but I don't want to continue working in the embedded industry (I'll leave the reasons behind the scenes). And from here I see the fading of interest in С/C++ outside of embedded (perhaps this is the wrong feeling).
Now I am facing a choice of a further career path: either I will further develop my C++ experience, study modern standards and look for a job outside embedded, or move to another area of software development (I'm looking towards iOS development). In addition, I have no experience in developing software for Windows.
What kind of non-embedded C++ projects can I potentially find work on in the modern world?
Are there any product-based companies that use C++ as the main language for their projects (ideally if it is an end user product)?
