Many of the types are bridged to the Swift type like as (e.g., NSString being bridged to String).
Other Objective-C types are bridged to Swift are as follows :
| Objective-C | Swift |
|---|---|
| NSString | String |
| NSArray | Array |
| NSDictionary | Dictionary |
| NSData | Data |
| NSError | Error (Added Swift 3 – Xcode 8 Beta 4) |
| NSNotificationCenter | NotificationCenter |
And more…
Bye Bye to NS from Swift!!
Happy Coding 🙂
