Hello, which version of XCode are you using?

[InShad7]

Xcode 14.2 MacOS 12

[TarekkMA]

Hello @InShad7,

Can you upgrade your Xcode to version 15 as per Flutter documentation?

[Movement83]

hello. did you solve this issue?

[InShad7]

not by updating the version because i cant be able to update because my macOS version is 12.

but i go through the errors and fix like this

Solution 1: StorageListTask file

   if (self.pageSize != nil) {
        queryParams["maxResults"] = "\(self.pageSize)"
   }

    if (self.previousPageToken != nil) {
        queryParams["pageToken"] = self.previousPageToken
  }

StorageDownloadTask file

 if  (self.fileURL != nil) {
    // Handle file downloads
        fetcher.destinationFileURL = self.fileURL
    fetcher.downloadProgressBlock = { [weak self] (bytesWritten: Int64,
                                                   totalBytesWritten: Int64,
                                                   totalBytesExpectedToWrite: Int64) in
        guard let self = self else { return }
        self.state = .progress
        self.progress.completedUnitCount = totalBytesWritten
        self.progress.totalUnitCount = totalBytesExpectedToWrite
        self.fire(for: .progress, snapshot: self.snapshot)
        self.state = .running
    }
  }

Solution 2:

StorageListTask file

  if let pageSize = self.pageSize {
    queryParams["maxResults"] = "\(pageSize)"
  }

  if let previousPageToken = self.previousPageToken {
    queryParams["pageToken"] = previousPageToken
  }

StorageDownloadTask file

  if let fileURL = self.fileURL {
    // Handle file downloads
    fetcher.destinationFileURL = fileURL
    fetcher.downloadProgressBlock = { [weak self] (bytesWritten: Int64,
                                                   totalBytesWritten: Int64,
                                                   totalBytesExpectedToWrite: Int64) in
        guard let self = self else { return }
        self.state = .progress
        self.progress.completedUnitCount = totalBytesWritten
        self.progress.totalUnitCount = totalBytesExpectedToWrite
        self.fire(for: .progress, snapshot: self.snapshot)
        self.state = .running
    }
  }

after do like this i can build.

How about lowering your Firebase storage version? 11.x.x ?

[TarekkMA]

Hello @InShad7, Can you delete your Pods/Podlock file and try again?

cd ios
rm -rf Pods && rm Podfile.lock
pod repo update
cd ..
flutter clean && flutter pub get

How about lowering your Firebase storage version? 11.x.x ?

when i lowered the version to 11.6.0 then the code comes like this without changing anything in the file and can compile successfully.

StorageListTask

    if let pageSize = self.pageSize {
      queryParams["maxResults"] = "\(pageSize)"
   }

  if let previousPageToken = self.previousPageToken {
     queryParams["pageToken"] = previousPageToken
  }

StorageDownloadTask

if let fileURL = self.fileURL {
// Handle file downloads
fetcher.destinationFileURL = fileURL
fetcher.downloadProgressBlock = { [weak self] (bytesWritten: Int64,
                                               totalBytesWritten: Int64,
                                               totalBytesExpectedToWrite: Int64) in
    guard let self = self else { return }
    self.state = .progress
    self.progress.completedUnitCount = totalBytesWritten
    self.progress.totalUnitCount = totalBytesExpectedToWrite
    self.fire(for: .progress, snapshot: self.snapshot)
    self.state = .running
}

}

Hello @InShad7, Can you delete your Pods/Podlock file and try again?

cd ios
rm -rf Pods && rm Podfile.lock
pod repo update
cd ..
flutter clean && flutter pub get

i tried this but wont change anything. After deleted the file and clean when i run pub get then also the same error within the file.

You mention that you are on macOS version 12 and thus unable to update to the latest version. Unfortunately, we will not be able to fix this from our side. You can still use an older version of the firebase_storage to test locally and use a CI tool to compile the app.
