Cocoapods: Default Xcode 12 settings fail to build CocoaPods-generate umbrella headers

[paulb777]

In Xcode 12 default options, CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER is set to Yes. This causes CocoaPods generated umbrella header files to fail with errors like:

Double-quoted include "FBLPromise+All.h" in framework header, expected angle-bracketed instead

Reported and additional discussion at https://github.com/firebase/firebase-ios-sdk/issues/5987

Reproducible project:
testProject.zip

Should we set CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER to NO for all Pods build settings?

[paulb777]

Yes, that should be safer and easier than generating different content for the umbrellas.

[amorde]

Is Xcode 12 now expecting umbrella headers to use <> imports?

[paulb777]

Yes.

[amorde]

Interesting - makes sense I guess. Apple does that in their own frameworks

I just updated to Xcode 12 and am experiencing this issue. How should I resolve it? After the update, the project can initially be successfully built, with a lot of The iOS Simulator deployment target is set to 8.0 warnings. So I updated all of their targets to 12.0. Then this quoted imports error appeared.

I did the following in order, but still get the error.

gem install cocopoads,
rm -rf ~/Library/Developer/Xcode/DerivedData/
pod deintegrate
pod update

Just upgraded Xcode and am unable to run my flutter app on Ios now as well. Looking for a fix

problem solved

1. this time I used pod deintegrate

2. pod install successes. (A few days ago, due to network reasons, there was a problem in this step. It's not true success before)

3. This project must run on true iPhone.

4. Actually, pod --version under the project directory is 1.9.3. I don't know why it's 1.10.1 outside. But it didn't affect the final result.

5. I run pod repo-art add cocoa-remote https://.... to make a local repo, below the directory ~/.cocoapods/repos-art. But when I pod install, It's don't download using local resource —— it's cause the pod install frequent failures.
