Answer 1

I was getting same error while i was uploading for apple review using Xcode 11.2.

Fixes steps: Apple decided to deprecate Xcode 11.2 on November 5th 2019. Xcode 11.2 has UITextView Building buggy code. So, Apple suggested to use Xcode 11.2.1 GM seed.

You can download from link https://developer.apple.com/download/

Message From Apple: This update fixes a critical issue that could cause apps using UITextView to crash when run on previous versions of iOS, iPadOS, or tvOS. Please see the release notes

You can build and release app using Xcode 11.2.1 GM seed. Hoping this will help some people.
