I had a project in unity 2019.2.21f for iOS which built successfully in Xcode ,
But tried the same project in unity 2019.4.19
But get 87 compiler issues
And you are targeting iOS 8 or newer?
some of your plugins uses (at least) enum from VideoToolbox.framework. Make sure it is added to the project
And you are targeting iOS 8 or newer?
well 2019 is ios10 min
Thank you my issue was resolved , the new unity.framework put a static lib i had created was put in the Embed Frameworks in Build Phases
