How to reproduce:
1. Open the attached project "IOSBitcodeIssue-2021.2.zip"
2. Build the project for iOS
3. Open Xcode project
4. In Xcode, click "Window -> Archive"
5. Once archiving finishes click "Distribute App" and proceed with the steps provided on the Window

Expected result: The App successfully passes Apple Validation
Actual result: The App fails Validation due to the following issue:
"ITMS-90562: Invalid Bundle - The app cannot be processed because options not allowed to be embedded in bitcode are detected in the submission. It is likely that you are not building the app with the toolchain provided in Xcode. Rebuild your entire app with the latest GM Xcode and submit the app again."

Reproducible with: Burst 1.6.0 (2021.2.0b12)
Not reproducible with: burst 1.6.0-pre.2 (2021.2.0b11)

Notes:
- Current Workaround is to downgrade the Burst package to a lower version, such as 1.5.6
