Build periodically fails with error: The compiler is unable to type-check this expression in reasonable time

[Alexeichua]

It happens in the source:
/Pods/Macaw/Source/model/draw/ColorMatrix.swift:60:17: The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions.

Enabling source editing and adding type to expression fixes the problem. New code look as follows:
let a: (Int) -> Double = { i in
m1[i] + c * m2[i] + s * m3[i]
}

Added type (Int) -> Double here. It would be great to have it out of box.
