SwiftComplex

Interact with Complex Numbers! This is a simple project which you can visually understand how complex multiplication works.

Complex

let z =  3 + 2 * i
let w = -2 - i
z + w ==  1 + i
z * w == -4 - 7 * i

Also supports polar form.

let z = Complex(r: 2, θ: M_PI / 4)
abs(z) == 2
arg(z) == M_PI / 4

Check out the code and see how simple they are implemented!

ComplexPlane

let cplane = ComplexPlane(frame: …)
cplane["1"] = Complex(1)
cplane["i"] = i

let z = Complex(r: 2, θ: M_PI / 3)
cplane["z"] = z
cplane.colors["z"] = UIColor.redColor()

let w = z * z
cplane["w"] = w
cplane.colors["w"] = UIColor.blueColor()

Here's the code.
