SecItemCopyMatching returns -25300

Question

I have the following codesnippet in my app.

    CFTypeRef result = nil;
    OSStatus userPresenceStatus = SecItemCopyMatching((__bridge CFDictionaryRef)query, &result);

SecItemCopyMatching returns -25300. It happens on some iPhone 6 devices but not on every device. What does this code mean ? What can be the cause ?

Thanks for your advice Frank

Answer 1

Error 25300 is errSecItemNotFound, which means that there is no such item in your key chain.

And you can find a list of potential result codes for Keychain Services here.

I'm guessing the keychain item you are trying to match against doesn't exist on that particular device.
