Xcode and SwiftUI is one answer. I’m tempted to upgrade my M1 Pro to an M3 Max. Reports suggest id halve my build times and then some.

... how long are your build times? If your build times are high enough to really affect your productivity, I feel like there are much cheaper (and environmentally friendly) ways to halve them

  (Not an ios developer, have worked with ios teams) Swift build times are notoriously awful. I don't know if most developers have much influence over that.

    They are okish a lot slower than c but still reasonable if you dont use tons of generics/macros and other heavy stuff. Still it could be a lot better.

  like what? genuinely curious. building native apps is notoriously painful

  Most places are unable to beat silicon advances to improve their build times.

  What's the point of posting this and providing zero examples of how?

    How could I possibly provide any advice. Of course build times are gonna be very specific to each project. I could tell you "just rewrite it in rust" but that obviously wouldn't be helpful

  I'd be happy to hear them :-) Ditching SwiftUI and going back to Obj-C would absolutely slash my build times ;-) But who wants to do that! The productivity gain is all about instant feedback and developer flow. It might be hard to justify on paper to an IT Manager in charge of budgets when you add up the minutes. But as I work for myself, it's easier. As for environmental concerns, well, two year used Macbooks don't go in the trash. Used Macbooks have very long lives in my experience!

How much RAM do you need for fast Xcode + Swift UI development?

  Nobody knows.

  Since the release of Xcode 15 it feels like the answer is, "More than 16 GB".

Geekbench for an M1 Pro multi-core is 11643, while the M3 Max (16 core) has a pref of: 21387. That would be a major upgrade so yeah, it is probably worth it of you can afford it.

  > Single Core Pref should be single core Perf, short for "performance"?
