macOS 工程报错 Error: Error Domain=NSPOSIXErrorDomain Code=1 「Operation not permitted」

在 macOS 工程中调试接口时出现报错：

Error: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <E0BD2CC5-BC74-4624-A308-020EECDC00AE>.<1>, _kCFStreamErrorDomainKey=1, _kCFStreamErrorCodeKey=1, _NSURLErrorRelatedURLSessionTaskErrorKey=(

), _NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, proxy, uses wifi}

解决办法：

在「TARGETS - Singin & Capabilities」中找到 App Sandbox，勾选：

• Incoming Connections (Server)
• Outgoing Connections (Client)
