Should I make an attempt at switching from Java to iOS development?

If you wanna dive in iOS specifics, well yes. If not, better try cross-platform.

Why not both?

@BimaAdi I’m wondering if I should focus more on iOS to get a job as an iOS dev.

How should we help you with that decision? You wanna develop iOS stuff? Go for it.

@TYML I'm more inclined to think that cross-platform means wider market and opportunities.

@TYML it really depends on your local job market.

@ravijojila I’d like to work remotely

@TYML can't help you there buddy, I have no experience in recent freelance world.
But same idea applies: find out how you would attract clients, and try to figure out what potential clients need. If you plan to use a freelancing portal, check posts to see what's needed.
Also, keep in mind seniority. If, for ex, they look for more senior android devs, but more junior ios, pick one that suits you better.
Also this approach helps you check what kinds of projects are more common on which platform. This may guide your decision.
