Expression was too complex to be solved in reasonable time

Doing a tutorial from RayWenderlich.

How to Make a Game Like Candy Crush with SpriteKit and Swift: Part 1

Updated for Xcode 9.3 and Swift 4.1. Learn how to make a Candy Crush-like mobile game, using Swift and SpriteKit to animate and build the logic of your game.

I have four bool values: topLeft, bottomLeft, topRight, and bottomRight

the following line throws an error:
let value = Int(topLeft.hashValue) | Int(topRight.hashValue) << 1 |
Int(bottomLeft.hashValue) << 2 | Int(bottomRight.hashValue) << 3

"Expression was too complex to be solved in reasonable time; consider
breaking up the expression into distinct sub-expressions."

This seems like a bug in the compiler, no? Is there actually a way to break
that up?

yeah,

let value1 = Int(topRight.hashValue) << 1
let value2 = Int(bottomLeft.hashValue) << 2
let value3 = Int(bottomRight.hashValue) << 3

let value = Int(topLeft.hashValue) | value1 | value2 | value3

"Expression was too complex to be solved in reasonable time; consider breaking up the expression into distinct sub-expressions."

This is a known issue that got worse with the new integer oriented protocols, especially with shifts.
