XCode archive error 'No such module flutter_downloader' when using AppDelegate.swift

[JHBitencourt]

I can't archive the project with XCode if I use AppDelegate.swift as stated in the docs.
Both flutter run --release and flutter build ios work.

• XCode: Version 11.3.1 (11C504)

• AppDelegate.swift:

import UIKit
import Flutter
import flutter_downloader

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    FlutterDownloaderPlugin.setPluginRegistrantCallback(registerPlugins)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

private func registerPlugins(registry: FlutterPluginRegistry) {
    if (!registry.hasPlugin("FlutterDownloaderPlugin")) {
       FlutterDownloaderPlugin.register(with: registry.registrar(forPlugin: "FlutterDownloaderPlugin"))
    }
}

I'm closing this issue since the problem wasn't this plugin. Some flavor and runner configurations got messed up, but now everything works fine.

Hi @JHBitencourt , how do you fix that? Could you show the code?

[batteryfull]

I was facing the same issue, tried to fix but no luck... @JHBitencourt Can you share with me the right config which fixed the issue?

[sunkaigoon]

Target iOS 9.0 to fix it.

[batteryfull]

thanks @sunkaigoon , I changed all of the targets to iOS 9.0, but still no luck... Will other configure need to be set too?

[hnvn]

Try to recreate ios project

flutter create -i swift .

[JHBitencourt]

@tronghuy5555 @batteryfull as I said my problem was because I have custom schemes, and my prod scheme was pointing to the build configuration of other one in the archive phase.

So neither changing target to iOS 9.0 or recreating ios project would work. And this last one is not indicated if you have custom configurations.

[batteryfull]

Many thanks, @hnvn and @JHBitencourt on your advise and update. But setting targets to iOS 9.0, re-create ios project but the error still present. I was using a custom scheme for different flavours and worked fine previously.
I did try a brand new flutter project and it works as expected after import flutter_downloader, I am trying to whether there is a conflict with other objective-C libs I was using.
I am open to your further advice on solving this issue as this is slowing us down.

Again thank you all!

[hnvn]

I have faced this kind of issue when I customize Xcode project with many flavours (build target). In my case, I recreate a simpler project to make sure the plugin work and compare the Xcode project setting of the working project with my original project line-to-line, it will point you out how to correct the project setting.

I have faced the same issue, made Product->Clean and Product->Build, its fixed the problem for me

[MunishThakur]

Any update on this. I am also facing "No such module 'flutter_downloader'" issue. I tried every step mentioned in the thread but nothing worked.

[KarimMohamed20]

Open xcworkspace instead of xcodeproj and it will work fine

[pengxueshan]

I am also facing "No such module 'flutter_downloader'" issue (debug mode is fine).

flutter/flutter#43986 (comment)
This comment resolve my problem.

Just change deployment target to 9.0 then everything worked well

[nivla360]

None of the above solutions worked for me so this is how I solved mine:

1. Run flutter clean
2. Open the project folder navigate to ios directory and delete the 'Pods' folder
3. Open terminal and navigate to ios directory in your project folder and run pod install
4. When done, open 'Runner.xcworkspace'
5. In Xcode, clean the build folder by going to Product > Clean Build Folder
6. Build the project (Product > Build) and everything should work fine.

[surveshoeb]

@nivla360 Thanks it worked for me.

[dthuering]

Also check if your iOS Deployment Target matches the Podfile platform setting.

[YuanSamuel]

@nivla360 Worked for me! I had to do some pod updates stuff as well, but right after building, it worked! I opened the ios folder instead on step 4, but there shouldn't be much of a difference.

Also had to restart Xcode.

This solved my problem. Thank you.
