This issue is only related to CODE SIGNING

But, the key point to note here is, if you are using XCode 11.x version. Not only the code signing in your project, but we should check the code signing in Thirdparty SDKs or dependencies that we add to our project.

Steps to verify the Code Signing of 3rd party SDks:

1. Download the source code of framework you need
2. Open the .xcproj file from the source code using XCode 11.x

3. Go to Targets -> Signing & Capabilities -> Select all tab -> Bundle Identifier If you see any unevenness in the identifier like, identifier with 4 seperators (Eg: com.company.mac.app)

   Change it to com.* and enter.

4. Make sure your XCODE COMMAND LINE TOOLS is set with XCode 11.x

5. Now, use below command to rebuild the SDK, with the changes done in above step-3

     carthage build --no-skip-current --cache-builds --platform iOS
   

6. Now copy the framework generated from, carthage folder of source code, and replace the existing SDK in your project.

Repeat the same for process for all the 3rd party SDKs, in your project.

NOTE: Make sure you marked all the 3rd party SDKs as Embed & Sign in

Targets => General => Frameworks, Libraries, and Embedded Content
