Sharing Keychain data between app and extension

问题

I am not able to get data in extension using Keychain Access.

What did I do ?

1. I have enabled the keychchain sharing capabilities in both the targets and gave the same identifier.

2. I have initialized the Keychain like this:

   static let keychain = Keychain(service: "teamID.com.appname.ios.sharedKeychain", accessGroup: "teamID.com.appname.ios.sharedKeychain")

I have also tried with just service/access group while initializing.

Error in extension ?

OSStatus error:[-25291] No keychain is available. You may need to restart your computer.

Xcode 11.3.1, Swift: 5

What is the problem in this approach ? There are many questions regarding sharing data between App and extension but still I am not able to find what's missing.

Note: This code works well on simulator. Thanks.
