CocoaPods frameworks compatibility: Step 2 (facebook#25619)
Browse files Browse the repository at this point in the history
Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in facebook#25393 (comment). If accepted, it will fix facebook#25349.

It builds on the changes I made in facebook#25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.

The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .

There are still a few breaking changes which I hope will be acceptable:

- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by facebook#25619 (comment).
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by facebook#25619 (comment).
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by facebook#25619 (comment).
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by facebook#25619 (comment).
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.

Still to do:

- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in facebook#25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by facebook@3357351.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �

[iOS] [Fixed] - Fixed compatibility with CocoaPods frameworks.
Pull Request resolved: facebook#25619

Test Plan:

```
buck build catalyst
```

Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.

You can see that it works with these steps:

1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`

The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.

`RNTesterPodsPods` can now work with or without `use_frameworks!`.

1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.
