无法在iOS 14上运行带有flutter的ios应用 [英] Unable to run ios app on iOS 14 with flutter

问题描述

我刚刚安装了iOS 14 beta，并将Xcode更新为最新的Version 12 beta 3.

I have just installed iOS 14 beta and updated Xcode to latest Version 12 beta 3.

从Flutter运行应用程序时，出现类似*Unable to locate DeviceSupport directory with suffix 'DeveloperDiskImage.dmg'. This probably means you don't have Xcode installed, you will need to launch the app manually and logging output will not be shown! Could not run build/ios/iphoneos/Runner.app on 00008020-001338A20E01002E. Try launching Xcode and selecting "Product > Run" to fix the problem: open ios/Runner.xcworkspace*的错误.

I get an error like *Unable to locate DeviceSupport directory with suffix 'DeveloperDiskImage.dmg'.

Try launching Xcode and selecting "Product > Run" to fix the problem: open ios/Runner.xcworkspace* when I run app from flutter.

我能够从Xcode运行该应用程序，但是一旦断开USB电缆的连接，该应用程序将无法打开/应用程序崩溃.

I am able to run the app from Xcode but the app won't open / app crashes once USB Cable is disconnected.

请帮助我找出问题所在并解决

推荐答案

我在Xcode 11.5中遇到了相同的问题 我转到 https://github.com/filsv/iPhoneOSDeviceSupport ，下载iOS 14，然后复制并粘贴到/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/中.效果很好.
