Both of these languages can be used to create Apple apps, but it's been said that Swift requires 60 less code in comparison with Objective-C. This is because we have to write less code in Swift for doing the same thing in Objective-C. 1 / 3 Rename refactoring Rename variables, constants, functions, type names and classes and rest assured that AppCode will update all the usages across the entire code base for you. Swift is considered to be 2.5 times faster than Objective-C in developing apps. Let's make a MyPoint.h file under the Sources/MyPoint/include path with the following contents. AppCode natively supports Objective-C, Swift, C and C++ (including modern C++ standards, libc++ and Boost), as well as JavaScript, XML, HTML, CSS and XPath. library(name: "MyPoint", targets: ),Įverything that you put into the header file will be publicly available for other developers to use, the implementation details are going to be located directly under the Sources// directory, but you have to create an additional include folder for your headers. swift-tools-version:5.3 import PackageDescription The only thing that you need to setup a library is a standard Package.swift manifest file with a slightly altered directory structure to support header files. If you don't know much about the Swift Package Manager, you should read my comprehensive tutorial about how SPM works. You can use the Swift Package Manager to create C family based source files (C, C++, Objective-C and Objective-C++) and ship them as standalone components. Swift Building a custom C library using SPM
