構建 Unity3D iPhone 項目時 Xcode 鏈接器失敗

Question

Unity 能夠構建 Xcode 項目，但是當我將項目構建到我的 iPhone 時，它​​會拋出 50 警告（我聽說這對 Unity 項目沒問題）並且在鏈接器上失敗。

Answer 1

似乎該庫的參考書被弄亂了。 嘗試刪除引用，然后再次添加。 有關如何執行此操作的更多信息以及其他建議，請參見這些類似的問題。

錯誤“找不到庫”

XCode鏈接器錯誤：-lAdMobDevice找不到庫

Answer 2

在“Unity --> 編輯 --> 項目設置 --> 播放器 --> iOS 設置 --> 其他設置 --> 目標最低 iOS 版本”（在我的情況下為 12.0）中將最低 iOS 版本更新為較新版本並修復Unity 版本“Unity Dashboard --> Cloud Build --> Config --> in iOS profile --> Basic Info Unity version”（在我的例子中為 2021.2.0b13）。 這解決了我的問題。
