HelloActually I want to implement some sort of client authentication in my iOS app wherein code inside the application can check for the app’s signer information and can also check if app is digitally signed by my specific certificate (e.g. signer name should contain xyz).This piece of code I want to have in my portable library (can be built for windows and iOS). For Windows there are direct APIs to check if the application is digitally signed and can also get the signer name. I am looking for similar option in iOS or at least any other way to check the digital signature of the current app and its signer information.Idea behind this check is to ensure that my library will be only used by the iOS application that is signed by my certificate.Only reference I got in this direction is: https://developer.apple.com/library/ios/documentation/Security/Conceptual/CertKeyTrustProgGuide/iPhone_Tasks/iPhone_Tasks.htmlBut this does not seem to serve the purpose.Please suggest your view to acheive required functionality.Thanks,Manish K
