Enumerated (enum) types are data types that comprise a static, ordered set of values I've been playing around with loading a list from CoreData and making changes on / filtering etc . An enumerated type is a distinct type whose value is a value of its underlying type (see below), which includes the values of explicitly named constants (enumeration constants) This is useful for many situations: For exampleIn SwiftUI if you add a system Image and TextField in a HStack it aligns them to make it look like the image is the representative of the TextField .

For example, here we create 3 Text views that print the numbers from 0 to 2: ForEach(0
element) If you define an enumeration with a raw-value type, the enumeration automatically receives an initializer that takes a value of the raw valueโs type (as a parameter called rawValue) and returns either an enumeration case or nil You can use segmented control to switch a given screen's content, for example, on filters or a list of items . A SwiftUI Picker view is a control that lets you pick a value from a set of options It has current, and next value keeps the object in it .
