I already searched f

Answer 1

A solution I found to work for me was

Inside the project root directory

root
  |- <ProjectName>
  |- <ProjectName>.xcodeproj
  |- <ProjectName>.xcworkspace
  |- <ProjectName>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 <ProjectName>.xcodeproj

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

Pods
|- Pods-<ProjectName>.debug.xconfig
|- Pods-<ProjectName>.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 <ProjectName>.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.

Answer 2

For me it works, update the version of CocoaPods and reinstall the pods

sudo gem install cocoapods

Answer 3

delete file name "Podfile.lock" and try pod install again.
