Xamarin.iOS 无法编译项目“应用程序是为比此模拟器更新的 iOS 10.2 构建的" [英] Xamarin.iOS Can't compile project "app was built for iOS 10.2 which is newer than this simulator"

问题描述

我正在使用 Xamarin.iOS，现在我正在使用 库(来自 GitHub) 提供了一些 Material UI 元素，它已经有一个 Xamarin 绑定和一些示例，问题是我无法编译示例项目.

I'm working with Xamarin.iOS, right now I'm doing some test with a library(from GitHub) that provides some Material UI elements, it already have a Xamarin binding and some samples, the problem is that I can't compile the samples project.

我收到以下错误:dyld:应用程序是为 iOS 10.2 构建的，它比此模拟器 10.1 更新

这是我尝试过的:

• 更新 Xcode(已经有最新版本 8.2.1 8C1002)
• 更新到 macOS Sierra
• 再次更新 Xcode(它说它为 Sierra 安装了一些新工具)
• 更新 Xamarin Studio(已经有最新版本)
• 更新项目包
• 尝试使用 10.2 创建模拟器，但它没有显示为选项
• 尝试安装 10.2 运行时，但它没有显示为下载选项
• 尝试在 10.2.1 (14D27) 的 iPhone 上运行
• 将部署目标更改为不同的版本

以上都没有奏效，我不断收到同样的错误.我对 iOS 开发还很陌生，我只在 Android 上使用过 Xamarin，所以我可能会遗漏一些明显的东西.

None of the above worked, I keep getting the same error. I'm very new to developing for iOS, I've used Xamarin for Android only, so I might be missing something obvious.

任何帮助将不胜感激.

推荐答案

在尝试了很多解决方案后，我最终完全重新安装了 Xcode，解决了我遇到的任何错误.

After trying a lot of solutions I ended up reinstalling Xcode completely, that fixed whatever error I had.

我建议任何有此问题或类似问题的人，如果在尝试解决此问题两三次后仍然有问题，请停止像我一样浪费时间并直接重新安装.

I suggest to anyone with this or similar problems that if after two or three attempts to fix this you still have issues, stop wasting time like me and go straight for a full reinstall.
