“StorageMetadata”类型的值没有成员“downloadURL”

我刚刚将 Firebase Storage 更新到 5.0.0，看起来像metadata.downloadURL()不再被认可。 （Value of type 'StorageMetadata' has no member 'downloadURL')

尽管查看文档后它应该仍然可用：

https://firebase.google.com/docs/reference/swift/firebasestorage/api/reference/Classes/StorageMetadata#/c:objc(cs)FIRStorageMetadata(im)downloadURL https://firebase.google.com/docs/reference/swift/firebasestorage/api/reference/Classes/StorageMetadata#/c:objc(cs)FIRStorageMetadata(im)downloadURL

该项目已经清理并重建。

我错过了什么吗？

你能试一下吗Google Firebase 文档 https://firebase.google.com/docs/storage/ios/download-files#generate_a_download_url

// Create a reference to the file you want to download
let starsRef = storageRef.child("images/stars.jpg")

// Fetch the download URL
starsRef.downloadURL { url, error in
  if let error = error {
    // Handle any errors
  } else {
    // Get the download URL for 'images/stars.jpg'
  }
}
