Not my experience at all. I develop daily in Xcode and compile times are excellent. One can't really compare between TS/JS interpreted languages and machine code generation. Apples and oranges. Swift compiler is fast, faster than C++. In my experience the Golang compiler is the fastest but the language is much simpler. Rust compiler is slower than C++.

As a side note, for some reason people like to bitch Xcode just out of habit perhaps. It's a kind of base line statement. Not my experience either. It's an excellent IDE for the current year of 2025. Helps me a lot and I build end-user facing apps, the proof is the love that users give to my apps. In other words, I have skin in the game.
