"Definitive Guide"..."Exhaustive"? Really? So why do I only find tips like changing from debug to release, or enabling 'Parallel build' which is enabled by default? And no mention of ccache? It's as simple as

    $ brew install ccache

Which will drop partial compile times from minutes to seconds.

I suggest people who are upvoting this actual look at the contents. I'm by no means an expert, but I found this "definitive guide" worthless. My guess is the author was learning how to use Xcode and these are his notes.

Presumably bots, like this other submission of op:

Those comments are cringey. I never thought bots were really on HN...

Looks like OP's colleagues that made an account just to comment, not bots.

I believe Swift occasionally has problems with type inference. If you time your builds and functions then you'll see where you need to add an explicit type.

I've also noticed image and color Assets take a while for an initial build.

For example, this little app of mine takes 25 seconds for a full build, and less than 1 second for an incremental, probably due to the 100 pictures.

Interesting points. Will give this a try myself.

Unfortunately ccache does not help with swift.

True, but this supposed "Definitive Guide" has plenty of references to Objective-C where it does help. My point was that I'm not an expert, and I see things missing.

Does it require any additional configuration?
