The guide provides instructions for integrating the Mixpanel iOS SDK into applications using either Objective-C or Swift, with a strong recommendation to use CocoaPods for easier version updates and dependency management. For users who cannot use CocoaPods, the guide details a straightforward process of manually integrating the SDK by cloning the "mixpanel-iphone" repository from GitHub, adding necessary dependencies, and initializing Mixpanel in the app's delegate file. The steps vary slightly between Objective-C and Swift, focusing on importing the relevant Mixpanel files and frameworks into the Xcode project. Users are encouraged to keep up with SDK updates by subscribing to the mp-dev Google group or watching the iOS repository on GitHub for new releases and updates.
