Xcode 12 compile error in ColorMatrix.swift

[jminutaglio]

In Xcode 12 (Version 12.0 beta 3 (12A8169g)):

Error:
The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

FIle:
ColorMatrix.swift

In:
public convenience init(hueRotate: Double) { let c = cos(hueRotate) let s = sin(hueRotate) let m1 = [0.213, 0.715, 0.072, 0.213, 0.715, 0.072, 0.213, 0.715, 0.072] let m2 = [0.787, -0.715, -0.072, -0.213, 0.285, -0.072, -0.213, -0.715, 0.928] let m3 = [-0.213, -0.715, 0.928, 0.143, 0.140, -0.283, -0.787, 0.715, 0.072] let a = { i in m1[i] + c * m2[i] + s * m3[i] } self.init(values: [a(0), a(1), a(2), 0, 0, a(3), a(4), a(5), 0, 0, a(6), a(7), a(8), 0, 0, 0, 0, 0, 1, 0]) }

Complier error is in the "let a =...." , line 60 in the file.
