Update and Recompile Xamarin Mobile App (IPhone version) using Latest Libraries

We are looking for an experienced Xamarin developer to update our mobile app, which is currently available on both Android and iOS platforms. Recently, Apple has notified us that they will remove the app from the App Store if it is not recompiled with the latest libraries. The app was originally compiled on a Mac, which has since undergone several updates, including updates to the OS, XCode, and Visual Studio. We need a freelancer to get our Mac operational again (the Mac works just fine, but the Xcode and related software do not, after the latest OS update) and recompile the app with the latest libraries so that we can submit an updated version to the App Store. Responsibilities: Assess the current state of the Mac and update the OS, XCode, Visual Studio, and any other necessary components to the latest compatible versions. Review the Xamarin mobile app's source code and update it to ensure compatibility with the latest libraries and frameworks. Recompile the mobile app for iOS using the updated libraries and ensure that it meets all of Apple's requirements for submission to the App Store. Test the updated app on an iPhone device to ensure smooth performance and compatibility. Provide detailed documentation outlining the changes made to the app, any potential issues, and suggestions for future improvements. Requirements: Proven experience in Xamarin mobile app development, specifically with Android and iOS platforms. Extensive knowledge of [login to view URL], XCode, Visual Studio, and other relevant technologies. Familiarity with updating and recompiling mobile apps to meet Apple's App Store requirements. Strong problem-solving and debugging skills. Excellent communication and documentation abilities. Additional Information: The Mac will be accessible remotely via TeamViewer, with the source code for the app already available on the machine. The updated app should maintain its existing functionality and features, with no significant changes to the user experience. The timeframe for this project is negotiable, but we would like to have the updated app submitted to the App Store as soon as possible. Please submit your proposal, including your relevant experience, a brief outline of your approach to the project, and an estimated timeline for completion. We look forward to working with you on this project and ensuring the continued availability of our app on the App Store.
