Lets create our first  Swift Package !  iOS Developer level : Intermediate   Configuration when this article was written   Xcode : Version 11.5 MacOS : 10.15.5 (Catalina)   A working example Final code can be found in the Resources section below.   What are Swift Packages ?   Swift packages are reusable components of Swift, Objective-C, Objective-C++, C, or C++ code that developers can use in their projects. They bundle source files, binaries, and resources in a way that’s easy to use in your app’s project. Enough of introduction , let’s be technical… From Xcode 11, we can directly create Swift Package. To ensure our package is rightly developed we will follow the steps mentioned below. Step 1 : We create a single view application , we will have a service (which we later export as swift package) developed here Step 2 : Create Swift Package with the same  single view application just developed, Move our service developed from our app to package. Step 3 : Once we find our service work

Access Control by using Access Specifiers  iOS Developer level :  Intermediate   Configuration when this article was written   Xcode :  Version 11.5 MacOS :  10.15.5 (Catalina)   A working example Final code can be found in the  Resources  section below.   Access control  restricts access to parts (like functions, class, structure, variables …. etc ) of your code from code in other source files and modules.   So lets understand what do we mean by Modules and Source Files  before we head forward   Modules and Source Files   A  module  is a single unit of code distribution—a framework or application that is built and shipped as a single unit and that can be imported by another module with Swift’s  import  keyword. In the example below (which I will coverup shortly) SharedFunctionality is a Module   A  source file  is a single Swift source code file within a module (in effect, a single file within an app or framework). In the example below (which I will coverup shortly) MySimpleClass.s
