Swift slow compile time

I have about 6 swift files with three iOS frameworks imported and compiling my projects takes about 10-15 seconds which is very slow.

I might have narrowed down it to a single swift file in my project that contains alot of code which according to the project navigater is taking more than 6 seconds to compile as opposed to the other swift files.

I chain a large amount of if else conditions in that swift file and I'm wondering if that is the reason why it takes so long to compile?

Adding type annotation to your variables helps compile times a lot. Most of the time is usually spent inferring the type.

  let foo: String = "FOO"
  let x: CGFloat = 1.0

In my experience adding type annotations for numeric types like CGFloat, Int is especially helpful.
