Fixing Classes/Launcher.swift:22:1: type 'UIApplication' does not conform to protocol 'Launcher'

• 12 min read

Today I upgraded flutter flutter upgrade, then compiled my Flutter app to iOS. It failed with this error:

Classes/Launcher.swift:22:1: type 'UIApplication' does not conform to protocol 'Launcher'

After searching for the error, I found https://github.com/flutter/flutter/issues/151467 as the first result. It turns out it is a known issue that has been fixed. The latest comment suggests upgrading dependencies by running flutter pub upgrade.

After which it told me I now was using url_launcher 6.3.1, which is the latest version according to pub.dev.

Yet when I tried to compile again, it told me this

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `GoogleSignIn` inside your development pod `google_sign_in_ios`.
   You should run `pod update GoogleSignIn` to apply changes you've made.

and then that:

❌  /Users/anhtuan/.pub-cache/hosted/pub.dev/url_launcher_ios-6.2.5/ios/Classes/Launcher.swift:22:1: type 'UIApplication' does not conform to protocol 'Launcher'

So I tried running those commands:

% cd ios
ios % pod repo update

Weird:

If you're using firebase dependencies you can upgrade them as follow(whichever you're using right now)

firebase_analytics: 10.8.9
firebase_auth: 4.17.8
firebase_core: 2.27.0
firebase_crashlytics: 3.4.18
firebase_messaging: 14.7.19
firebase_storage: 11.6.9

then flutter clean and pod install. Should work

Here's what my pubspec.yaml looks like:

  flutter:
    sdk: flutter

  firebase_auth: ^4.2.1

Now the only error in red left is this:

▸ Touching FirebaseCoreInternal_Privacy.bundle (in target 'FirebaseCoreInternal-FirebaseCoreInternal_Privacy' from project 'Pods')

❌  error: unsupported option '-G' for target 'arm64-apple-ios9.0' (in target 'BoringSSL-GRPC' from project 'Pods')


▸ Compiling tls_record.cc

❌  clang: error: unsupported option '-G' for target 'arm64-apple-ios9.0'

This error was reported in June. https://github.com/grpc/grpc/issues/36888

My Podfile.lock states that I am on this version:

BoringSSL-GRPC (0.0.24):

The solutions posted in the thread do not really apply to me. They suggest patching out the -G parameter in the Podfile. This is ugly and I am certainly not copy/pasting this in each and every one of my projects.

A further search brought me to this: they give the versions of firebase that worked for them:

firebase_core: 3.6.0
firebase_auth: 5.3.1
cloud_firestore: 5.4.4
firebase_messaging: 15.1.3
firebase_storage: 12.3.3
cloud_functions: 5.1.3
BoringSSL-GRPC unsupported option ‘-G’ for target ‘arm64-apple-ios15.0’
After updating to the XCode 16 Beta, when building app i get this error (in attachments), thats basically it. Is there any way to fix that or should I wait for BoringSSL update?I’ve tried pod upda...
