Why implementation of the sequence protocol is said destructive?
Is implementation of sequence protocol , destructive ? Why and how! Sequence type is said to provide sequential, iterated access of its elements. Think of a sequence generator which can be used to create user id's, from a starting point. public struct UserIdSequenceGenerator : Sequence { private var startId : Int public init (startId: Int ){ self . startId = startId } } extension UserIdSequenceGenerator : IteratorProtocol { public mutating func next () -> Int ? { defer { startId += 1 } return startId } } Requirements on implementing Sequence Protocol. First Approach. Override make Iterator() method which returns IteratorProtocol object. Second Approach Make the UserIdSequenceGenerator...
