What are the prospects for iOS development on swift?

Question

IT education

Recently, more and more interested in the topic of mobile development.
Having studied the job market and the trends of recent years, I have formed an opinion that soon (2-3 years perspective) cross-platform development (ReactNative or Flutter) will start to replace the native one.
I'm not saying that native languages ​​like swift / obj-c will go into oblivion, but separate components will be written on them, which will later be ported to cross-platform frameworks.
Hence the question, what are the prospects for native languages, or is my guess correct and cross-platform development is starting to push the native?

Once again, the mobile development industry is unfamiliar to me and I could be wrong.
