I will not spend too much time explaining Objective-C, and I will assume you are familiar with iOS development. The purpose of this tutorial is to give Objective-C developers a quick overview of new Swift language features, helping you take the next step and begin adopting Swift in your everyday work. It is a perfect moment to start exploring this new language as it is obviously the future of iOS development. Swift 1.0 is already a stable and strong development platform, which is sure to evolve in interesting ways over the coming years. Swift removes the unsafe pointer management and introduces powerful new features, while maintaining interaction with both Objective-C and C. Once again, iOS developers will need to learn a new programming language: Swift. Apple continually improved Objective-C with each release, adding blocks and literals, simplified memory management with automatic reference counting, and many other features indicative of a modern programming language.Īnd after 6 years improving and working on Objective-C, Apple decided to throw another challenge at developers. Despite unfamiliar syntax and manual memory management, it was immensely successful, helping populate the App Store with tens of thousands of apps. Many of these developers had never used Objective-C before, and that was the first challenge Apple threw at them. They are now recognized as iOS developers.

This event started another revolution in software development, and a new breed of developer was born. It is not necessary to use bzero, getCString, malloc, here is an example that does not:Īdd #import to the bridging header.In 2008 Apple announced and released the iPhone SDK 2.0. Key.getCString(&keyPtr, maxLength: 17*sizeof(Character), encoding: NSUTF8StringEncoding)

Var keyPtr: Array = Array(count: 17, repeatedValue: '0')

I was trying using UnsafeMutablePointers and I also tried the code below, but I know it is completely wrong: var key: NSString = 'BitCave012345678' Return ĭoes anyone has an idea how to satisfy arguments requiring pointers? Size_t bufferSize = dataLength + kCCBlockSizeAES128 ĬCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionECBMode, I'm not sure how to use functions like: bzero, getCString, malloc in Swift. I really need some help to convert the objective-c code to swift using CryptoSwift.
