Do you have experience working with project management systems or package managers used in projects?

Yes, in projects for iOS, I often used project management systems and package managers:

• Xcode — the main IDE for iOS app development, includes project management, building, and debugging.
• CocoaPods — dependency manager, allows easy integration of third-party libraries.
• Carthage — an alternative package manager, simpler and less intrusive.
• Fastlane — a tool for automating builds, testing, and app publication.

For example, to include a library via CocoaPods, just add to the Podfile:

pod 'Alamofire', '~> 5.4'

and run pod install to install dependencies.
