升级后Xcode上的Flutter应用将无法启动 [英] Flutter app on Xcode won't launch after upgrade

问题描述

我有一个使用Flutter开发的应用程序，并且由于最新版本的Xcode绝对无法像以前一样工作. 我已经为这个问题苦苦挣扎了近一个星期，错误依小时而异.

I have an app made in Flutter and since the latest version of Xcode absolutely nothing works as before. I have been struggling with this problem for nearly a week now and the errors vary depending on the hour.

主要问题是，将应用程序分发给Apple进行审核时，他们拒绝并显示以下消息:

The main problem is that when distributing the application to Apple for review, they reject it with the following message:

2.1性能:应用程序完整性指南

2.1 Performance: App Completeness Guideline

2.1-性能-应用程序完整性

2.1 - Performance - App Completeness

在iPad上进行审核时，我们在您的应用中发现了一个或多个错误 在Wi-Fi上运行iOS 14.0.

We discovered one or more bugs in your app when reviewed on iPad running iOS 14.0 on Wi-Fi.

具体来说，我们仍然无法通过使用Apple登录进行登录

Specifically, we were still unable to login through Sign in with Apple

---

我觉得很奇怪，因为以前所有上传的内容都经过了验证，没有任何问题. 因此，为纠正此问题，我尝试通过模拟器运行该应用程序，因为我没有iPad. 问题就从这里开始.

---

I find this strange as all my previous uploads got verified without any problems. So to rectify this issue I'm trying to run the app through the simulator as I don't own an iPad. And here is where the problems start.

侧面说明:在物理iPhone上运行不会出现问题，我正在打开项目runner.xcworkspace，而不是runner.xccodeproj.

Side note: Running on a physical iPhone works without problems and I'm opening the project runner.xcworkspace, not the runner.xccodeproj.

主要问题是，从第一个库开始，Xcode找不到任何库:

The main problem is that Xcode won't find any libraries, starting with the first one:

GeneratedPluginRegistrant.m:10:9:找不到模块"apple_sign_in"

GeneratedPluginRegistrant.m:10:9: Module 'apple_sign_in' not found

我尝试了与此问题相关的所有解决方案，但无济于事.

I have tried every solution related to this issue but to no avail.

• 删除pod文件，pod安装
• pod取消集成，pod初始化，pod安装
• flutter构建ios --release，flutter运行
• 我尝试删除我的项目并克隆它以重新开始
• 有时候甚至连样板程序都无法使用
• 我已经检查了github帖子，例如 https://github.com/flutter/flutter/issues /53573 和 https://github.com/flutter/flutter/issues/33423 没有运气.
• ...检查了无数线程.

• Remove the pod files, pod install,
• pod deintegrate, pod init, pod install
• flutter build ios --release, flutter run
• Ive tried removing my project and cloning it for a fresh start
• Sometimes not even a boilerplate app will work
• I have checked github posts like https://github.com/flutter/flutter/issues/53573 and https://github.com/flutter/flutter/issues/33423 with no luck.
• ...checked countless threads.

推荐答案

Flutter 1.20.4和XCode12/iOS14存在问题.
您需要将Flutter更新到当前的Beta(1.22.0-12.3.pre)，其中包含许多针对新的iOS/XCode版本的修复程序.

There are problems with Flutter 1.20.4 and XCode12/iOS14.
You need to update Flutter to the current beta (1.22.0-12.3.pre) which contains a lot of fixes for the new iOS/XCode versions.

请参见 https://flutter.dev/docs/development/ios-14
