Answer 1

A solution I found to work for me was

Inside the project root directory

root
  |- 
  |- .xcodeproj
  |- .xcworkspace
  |- Tests
  |- Podfile
  |- Podfile.lock
  |- Pods

Delete the following files. Ensure you have copied the contents of Podfile.

1. Podfile
2. Podfile.lock
3. Pods Folder

Open your .xcodeproj using Xcode or using terminal command

open .xcodeproj

Inside Xcode, locate the "Pods" folder which should contain something along the lines of...

Pods
|- Pods-.debug.xconfig
|- Pods-.release.xconfig

Delete those references and select "move to trash" when prompted.

Close Xcode

Now run the following:

pod init && pod install

Open your Podfile and paste in your previously copied old Podfile that was deleted earlier.

run the following command:

pod install

In terminal open Xcode again with the following command

open .xcworkspace

Note: that I opened the xcworkspace file NOT the xcodeproj file.

At this point for me I was able to compile my code as normal without having to change back to the Legacy Build System.
