Swift: Recursive enumeration
Recursive enumeration in Swift is a enumeration which has a instance of another enumeration as one of the associated values of the enumeration cases. We indicate recursive enumerations with the …
Swift: Initializing from rawValue
When we define a enumeration with a raw value type, Swift provides a default initializer that takes the value of that type’s raw value as a parameter and return a …
Swift: Implicitly assigned rawValues
In enumerations, we can provide default value for the cases. The values must be of same type. If we are to provide String values and Int values as default values …
Swift: Difference between rawValue and associated value in enumeration
Associated values allows as to store additional custom information along with case values which can be altered every time when we use that case in our code. Each case can …
Enum showing RawRepresentable error on using CaseIterable protocol
CaseIterable protocol is used to access the entire collection of values contained within a type if that type conforms to this protocol. This is done by using the allCases property. This …
Swift: How to access all the enumeration cases using CaseIterable protocol?
Types that conform to ‘CaseIterable protocol’ can let us access their entire collection of values by using their ‘allCases’ property. For example, enumeration type without associated values.Sometimes we need to …
Swift: How to use associated values in enumeration ?
