Linker error when using ApolloSQLite with bitcode enabled

[mochimoshi]

#475 was merged recently, which made Apollo + ApolloSQLite compatible on Xcode 10.2. However, this also included changes in build settings to explicitly enabling Bitcode and setting Bitcode generation modes on physical iOS devices in Apollo and ApolloSQLite in Configuration/Shared/Workspace-Universal-Framework.xcconfig. This leads to a linker error:

ld: bitcode bundle could not be generated because '~/Library/Developer/Xcode/DerivedData/SampleProject/Build/Products/Debug-iphoneos/SQLite.framework/SQLite' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file '~/Library/Developer/Xcode/DerivedData/SampleProject/Build/Products/Debug-iphoneos/SQLite.framework/SQLite' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The best solution seems to be submitting a change to https://github.com/stephencelis/SQLite.swift/ so that their framework also enables bitcode generation on devices in debug builds, but in the meantime, can Bitcode generation (at least for iOS devices) be set to marker instead of bitcode in debug? This is blocking me from building my project onto my device.

For reference, I'm using git submodules at add Apollo and ApolloSQLite into my project.

Thanks!
