iOS Deploy is failing

[Jag96]

Problem

The Build and Deploy iOS workflow is failing with the following error:

❌  ld: could not reparse object file in bitcode bundle: 'Invalid bitcode version (Producer: '1205.0.22.9.0_0' Reader: '1200.0.32.28_0')', using libLTO version 'LLVM version 12.0.0, (clang-1200.0.32.28)' for architecture arm64
❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

This failed for the following runs so far:

• https://github.com/Expensify/App/runs/3205175704
• https://github.com/Expensify/App/runs/3205382335

Looks like this is related to Xcode versions: https://stackoverflow.com/questions/63802570/invalid-bitcode-version-for-archiving-ios-app, version info is here: https://trac.macports.org/wiki/XcodeVersionInfo

What version of XCode are we on now?

[Jag96]

Looks like 12.3:

App/.github/workflows/platformDeploy.yml

Line 13 in a1b717a

DEVELOPER_DIR: /Applications/Xcode_12.3.app/Contents/Developer

Going to bump that and the other usage, rebuild, and see if I can archive without errors

Weird that e2e is passing 🤔

So I think that'll pass fine since the fastlane linker command isn't called there
