Should I upgrade my MacBook Pro M1 Pro to MacBook Pro M4 max?

I used to be a full-stack developer before 2025.

For web development my current MacBook Pro M1 Pro suits perfect: very fast, no noticeable slow downs. Even with 16 GB of RAM.

started iOS and macOS development in 2025. And since then i started to feel noticeable slow downs pf my machine whenever I do something in Xcode.

And it's not even that I feel that the build time is very long. It's about plain project navigation and editing TEXT code files in Xcode.

So I'm wondering now whether or not should I upgrade to a newer MacBook with more RAM and whether or not I'm going to notice that the newer MacBook is MUCH faster and much more pleasant ro work on.

Have anybody had this kind of upgrade? What are your observations regarding the difference when it comes to iOS and macOS development?
