Libraries and Frameworks Showcase

It is a sample project, that shows how to create and use frameworks in Swift, Objective-C and mixed projects.

Short recap: Frameworks are just dynamic libraries, that are wrapped in a bundle and have some additional resources

It consists of a client app (Libs & Frameworks Showcase target) and several types of libraries:

• Framework in Swift
• Framework in Objective-C
• Framework in Swift and Objective-C

The client application has 2 classes, that make use of all the libraries: a Swift class SwiftDependenciesClient and an Objective-C class ObjectiveCDependenciesClient. So you can see how to import any type of library in client app, and the languages don't matter here.

Swift framework: how to add and use

1. Add a new Framework target (choose Swift language).
2. Add .swift files to the new target.
3. Remember, only open and public types are visible outside the module.
4. Import the framework in the swift file, where you need it (import SwiftFramework).
5. Import it in Objective-C file via @import SwiftFramework;
6. Use it!

Swift & Objective-C framework: how to add and use

1. Add a new Framework target (choose any language)
2. Add .swift files
3. Add .h and .m files
4. Import the headers in the umbrella header of the framework (SwiftObjectiveCFramework.h in our project):

#import <SwiftObjectiveCFramework/OBJSwiftObjectiveCFrameworkClass.h>

5. Remember, that only open and public Swift declarations are visible outside the module.
6. Import the module in the Swift or Objective-C files of the client app.

Objective-C framework: how to add and use

1. Add a new Framework target (choose Objective-C language).
2. Add some classes.
3. Import the headers in the umbrella header of the framework (ObjectiveCFramework.h in our project):

#import <ObjectiveCFramework/ObjectiveCFrameworkClass.h>

4. Import the module in the Swift or Objective-C files of the client app.
