I'm curious if there's a reason CGRect, CGPoint, CGVector, and CGSize are not Hashable?
Writing an extension was easy enough, it just seems odd, and I couldn't find any discussion about it anywhere.
Core Graphics: CGRect, etc. not Hashable
AFAIK, t-uples are not dirctly hashable.
For instance, (Int, Int) is not hashable, but can also get an extension to make it hashable.
I found on SO this elegant way to make anything hashable, here for CGRect
extension CGRect: Hashable {
public var hashValue: Int {
return NSCoder.string(for: self).hashValue
}
}
