![]() ![]() In Swift 3, the id type in Objective-C now maps to the Any type in Swift, which describes a value of any type, whether a class, enum, struct, or any other Swift type. These conversions were inconsistent with the rest of the language, making it difficult to understand what exactly could be used as an AnyObject, resulting in bugs. ![]() Swift 2 also provided implicit conversions to AnyObjectfor some bridged value types, such as String, Array, Dictionary, Set, and some numbers, as a convenience so that the native Swift types could be used easily with Cocoa APIs that expected NSString, NSArray, or the other container classes from Foundation. For instance, Swift 2 mapped the id type in Objective-C to the AnyObject type in Swift, which normally can hold only values of class types. Swift 3 interfaces with Objective-C APIs in a more powerful way than previous versions. For the latest news, visit the Swift open source blog ![]()
