I have the Source Code for the First SDK and the Second SDK is developed by a third party vendor and we do not have access to their source code. I have prototyped the second SDK functionality by creating a Sample App written in Objective C, invoking the first SDK code and for the second SDK code, I wrote a sample word "Hello" to the Keychain using Objective C but when I read it, it comes back as item not found(which is the root issue). I can share the zip file which contains this Sample App, can you please share a link where I can drop this zip file? The root issue is pretty straightforward, if we write to keychain with one key(lets say key1) using Swift and again write to the keychain using Objective C using a different key(lets say key2) and try to read the values from the keychain using the keys, for key 2 the value is coming back as item not found and this happens only on a Simulator and works fine on an actual iPhone. Any input/help you can provide is highly appreciated. Thanks.
