I think it’s too much to require Swift developers not just to profile their code to improve running times but also to profile the compilation of their code to reduce compile times.
Swift should automatically identify expressions that took too long to compile and automatically insert type annotations in the source code to speed up future compiles of those expressions.
I respectfully disagree. The Swift compiler should just not require you to change your code in order for it to compile fast. We’re working on it.

These should be fix its but the problem is the compiler needs to be able to compile it in order to know what needs fixing but it can't do that if it took time to compile ;)

Yes it can up to a certain limit like 30 seconds.

I thought this type inference is exponential in the worst case.
