Swift Evolution - Enum Case Count Functionality

Swift Evolution Proposal

Author: Andyy Hope

Enum Values() Functionality (Update)

It has been brought to my attention that there was more use for the unintended values() functionality that I had outline in my "Other Languages" Java example below.

On the Swift Evolution mailing list, one developer outlined their requirement to loop through an array of enum case values to add different states to objects.

Another example where a values array would be useful if the developer wants to do something different for each different case, such as setting an image on a UIButton subclass for each different UIControlState

Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)
# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions
# (A similar approach works for older versions too, just change the version number after DeviceSupport)

extension UIImage {
// colorize image with given tint color
// this is similar to Photoshop's "Color" layer blend mode
// this is perfect for non-greyscale source images, and images that have both highlights and shadows that should be preserved
// white will stay white and black will stay black as the lightness of the image is preserved

A UIAlertController with a text field and the ability to perform validation on the text the user has entered while the alert is on screen. The OK button is only enabled when the entered text passes validation. More info: https://oleb.net/2018/uialertcontroller-textfield/

public enum TextValidationRule {
/// Any input is valid, including an empty string.
case noRestriction
/// The input must not be empty.
case nonEmpty
