Issue Description:
I was exploring the new async/await feature by downloading the March 25th, 2021 development snapshot from the Swift.Org site.
I entered the concurrency flag as mentioned in the Swift async-await proposal, I tried calling two APIs serially using async-await but then when I ran the project I got a crash.
Steps to replicate the crash:
Open the attached project zip file
Run the application
The app will crash here
