Answer 1

我遇到了類似的問題，對我來說，問題是由於在 XCode 中打開 Runner.xcodeproj 而不是 Runner.xcodeworkspace 引起的。 對於使用 XCode 的人來說，這似乎很明顯，但也許這會在某個時候對某人有所幫助。

Answer 2

您似乎缺少庫嘗試：

1. flutter clean
2. flutter build ios

Answer 3

我花了幾個小時試圖修復未找到的庫上的類似錯誤。 最終這就是我能夠解決它的方式

1. 在開始使用 Xcode Archive 之前，使用 flutter build iOS
2. 將 IOS 部署目標更改為更高的目標 iOS 11.2 。 早些時候我有類似 8.0 的東西，它給出了上述所有錯誤。
3. 確保 Xcode 中的 IOS 部署目標在 Project、Target 和 Pods 中相同
