There is no single correct answer as it always depends on a huge amount of variables, many of which are in constant flux. You yourself will almost always have the most accurate information to make a decision what's best for you. Spend a year with Rust and a year with Swift. Then you'll be at a far superior position to choose which one of those to invest more years in, or to look for a third language. Which one to choose first? It doesn't matter, flip a coin if the decision is difficult. Learning many languages/frameworks/styles will make you a better programmer than just investing decades into some supposed unicorn.
