这是我第一次在MacbookPro上安装XCode

我正在使用macOS Catalin版本10.15.4

我尝试过的

安装不同版本的Xcode：11.4、11.3、10.1
sudo rm -rf /Library/Developer/CommandLineTools && xcode-select --install
sudo xcodebuild -license
删除〜/ Library / Caches
删除/ Library / Caches
删除〜/ Library / Developer
defaults delete com.apple.dt.xcode

Answer 1

尝试删除〜/ Library / Developer / Xcode中的DerivedData目录

或

尝试卸载Xcode，然后重新安装

Answer 2

看起来您的默认设置可能有问题。尝试运行以下命令清除它们

defaults delete com.apple.dt.xcode

Answer 3

最有可能在代码中的某个地方，将NSNumber变量分配给NSString变量。
因此，数字对象（实例0xed1bd6c1b1e0a897）无法响应hasPrefix: method。

2020-04-05 14:51:44.095 Xcode[5709:184457] -[__NSCFNumber hasPrefix:]: unrecognized selector sent to instance 0xed1bd6c1b1e0a897

尝试调试并弄清楚该对象实际上是0xed1bd6c1b1e0a897，在哪里创建并分配给字符串对象。找到它后-您可以使用NSString property轻松地将其转换为stringValue。

我认为您能够构建该项目。如果Xcode在构建和运行之前就崩溃了-我不知道。

Answer 4

尝试删除所有这些文件夹吗？

~/Library/Containers/com.apple.dt.BitbucketServerHostBuiltInExtension
~/Library/Containers/com.apple.dt.GitHubEnterpriseHostBuiltInExtension

~/Library/Containers/com.apple.dt.IDECacheDeleteAppExtension
~/Library/Containers/com.apple.dt.XCDocumenter.XCDocumenterExtension

~/Library/Preferences/com.apple.dt.Xcode.Playground.plist
~/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Preferences/com.apple.dt.xcodebuild.plist

Xcode在打开新项目后立即崩溃

我尝试过的
