Emulator for IOS 15.0.0 crashes

Is this a support request?
No

Describe the bug
IOS app crashes on the ios simulator for 15.0.0

To reproduce
I am using this code to retrieve all the flags on an ios simulator for 15.0.0 and it crashes the app on the simulator

let allFlagsResult = client.allFlags();
    allFlagsResult.then(values => {
      console.log(values);
    });

Expected behavior
I expect all the flags from the env to be retrieved and logged
