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

UIEdgeInsets separatorInset = UIEdgeInsetsMake(0, 0, 0, 0);
    
    // Remove seperator inset
    if ([self respondsToSelector:@selector(setSeparatorInset:)]) {
        [self setSeparatorInset:separatorInset];
    }
    
    // Prevent the cell from inheriting the Table View's margin settings
    if ([self respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]) {
        [self setPreservesSuperviewLayoutMargins:NO];
