[🐛] Bug - 'headerValue()' is unavailable in Swift: Use `asyncHeaderValue() async -> String?` instead.

[VadymBezsmertnyi]

Good day, I have an error after the last pod update, specifically:
'headerValue()' is unavailable in Swift: Use 'asyncHeaderValue() async -> String?' instead.
This occurs in the file AuthBackend.swift.
I am attaching screenshots:

Also, here is my package.json:

Same issue here, happening when building on EAS server's but not locally

[mikehardy]

Are you able to reproduce the bug with my build issue reproducer here? https://github.com/mikehardy/rnfbdemo/blob/main/make-demo.sh

just need to plop a google services json/plist file in there and bump the RNFB version to 21.1.0 (though, I've been using firebase-ios-sdk 11.3.0 forever already and it worked...)

I suspect something going on with caching or something, or perhaps the firebase-ios-sdk version is overriden in the Podfile or something?

Because I haven't had any build problems like this either here in the e2e test suite app or my build reproducer 🤔

[PavelShev]

Same errors here in class AuthBackend

@mikehardy
Hey)
Here are the changes I updated and couldn't revert:

[mikehardy]

I think it's because 11.4.0 came out and we're getting a mix of dependencies - thanks @PavelShev for posting that - very instructive

workaround - pin firebase-ios-sdk in Podfile to 11.4.0 like so: https://rnfirebase.io/#ios

I'm not sure if you can do that in Expo. Looks like we need a release here that can either pin the versions to "same or lower than" firebase-ios-sdk instead of letting them drift since it appears they aren't semantic versioning-safe, or to update to 11.4.0

[DiazIgnacio]

For a managed Expo app I made a temp plugin to solve this:

/* eslint-disable no-undef */
/* eslint-disable quotes */
/* eslint-disable @typescript-eslint/no-var-requires */
const { withDangerousMod } = require('@expo/config-plugins');
const fs = require('fs');
const path = require('path');

const withTempFirebaseFix = (config) => {
    return withDangerousMod(config, [
        'ios',
        (config) => {
            const podfilePath = path.join(config.modRequest.platformProjectRoot, 'Podfile');
            let podfileContents = fs.readFileSync(podfilePath, 'utf-8');

            //  Fix for the Podfile
            const fix = `
    # Fix 'headerValue()' is unavailable in Swift: Use asyncHeaderValue() async -> String? 
    # https://github.com/invertase/react-native-firebase/issues/8073
    $FirebaseSDKVersion = '11.4.0'

`;
            if (!podfileContents.includes("$FirebaseSDKVersion = '11.4.0'")) {
                podfileContents = fix + podfileContents;
                fs.writeFileSync(podfilePath, podfileContents);
            }

            return config;
        },
    ]);
};

module.exports = withTempFirebaseFix;

[mikehardy]

I've got a PR in CI right now in #8074 that contrains the transitive dependencies a lot more tightly
Some of them are still slipping out to 11.4.0 but the build passes for me now?

I will also be pursuing the actual firebase-ios-sdk update as a separate item but this should get people building again assuming CI here goes green and I can hit the merge + publish buttons

[mikehardy]

@DiazIgnacio this is actually a pretty useful plugin in general, as there is no other way I'm aware of to set the Firebase SDK version in Expo since it is direct in the Podfile - thanks for posting that

[maximmai]

also experiencing this with flutter version 3.24.3 and FirebaseAuth version

#  firebase_analytics: ^10.5.1
#  firebase_auth: ^4.10.1
#  firebase_messaging: ^14.6.9
#  firebase_crashlytics: ^3.3.7
#  firebase_dynamic_links: ^5.3.7
#  firebase_in_app_messaging: ^0.7.3+7

[mikehardy]

v21.1.1 is out with transitive dependencies contained enough that it should work for react-native-firebase folks

https://github.com/invertase/react-native-firebase/blob/main/CHANGELOG.md#2111-2024-10-22

If you have added a version pin, you should probably take it out as soon as possible - it is easy to forget those and they turn into landmines in the future

@maximmai I'm afraid I can't help as this is not the correct repository for that, although I will mention it internally to the Invertase crew as they should be able to have an effect on the flutter plugins. If there is a way to pin your firebase-ios-sdk dependency in the flutter firebase plugins then pinning it to 11.4.0 should fix things for you - but I don't know if there is a mechanism to do so or not - it looks like there might be but I haven't tested it

[VadymBezsmertnyi]

@mikehardy
Thank you for the quick fix. I updated everything, and it works well)
