So I am working on an old Xcode project that was developed by a separate developer and am having build errors when running on my Mac due to Cocoapods. The first error is "The sandbox is not in sync with the Podfile.lock”, which I can fix by removing the various Cocoapods files and the old xcworkspace from the project and running pod install in the terminal to create all of this again. The new issue is that some of the classes cannot find the header files from the podfile's listed frameworks.
My theory is because this is an old project and the old developer didn't put version caps on some of the frameworks in the podfile, is that the project is trying to use old methods / classes that are deprecated in the newest updated frameworks. However I am not sure how to get around this as I tried putting version caps on those frameworks in the podfile without any success.
