Compile Time Incredibly Slow

Question

My project consists of ~350 Swift files and ~40 cocoa pod dependencies.

As soon as the entire project was migrated to Swift 3, build times have been <

Answer 1

Concatenating several Strings also can cause increasing compiling times, for example in my case, my compilation times where very high because of this line:

let fecha = post.dia + " " + post.num_dia + " " + post.mes + " - " + post.hora

When i changed the code to this, it satart compiling in seconds:

var fecha = post.dia!
fecha = fecha + " "
fecha = fecha + post.num_dia!
fecha = fecha + " "
fecha = fecha + post.mes!
fecha = fecha + " - "
fecha = fecha + post.hora!
