User info payloads should respect the following types: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/PropertyLists/AboutPropertyLists/AboutPropertyLists.html otherwise receive user info throws a native error

@mtford90 I wasn't sure if I should write here, the other issue linking here or create a new one.

Before I go into details, the issue I am seeing is that sendMessage works fine and transferUserInfo doesn't trigger any of the relevant delegate methods (didReceiveUserInfo, didFinish).

Testing simulators should work, right? Is this related? The payload is literally copy/paste from the docs.

@RWOverdijk always best to test on real devices - I've found in the past that pairing simulators is extremely flaky - this is noted in the troubleshooting section of the docs.

Oh never mind me, I wrote my app natively instead, much easier. Thanks for replying though!
