Adding an Existing Framework to a Project
Add a framework bundle to a project in order to incorporate the framework’s features into your product.
In the project navigator, select the project or group within a project to which you want to add the framework.
Choose File > Add Files to “<App_Name>”.
Select the framework bundle, and click Add.
The frameworks you add this way are third-party-built bundles containing the framework’s object code and runtime resources. See related articles for information about linking to a framework without adding it to the project.
After you add the framework, Xcode configures the targets in your project to link them to the framework just added.
