处理命令时遇到错误（domain = IXErrorDomain，code = 2）：无法为应用程序包ID创建IXPlaceholder io.ionic.starter

Question

运行ionic cordova run ios

时出现以下错误

** BUILD SUCCEEDED **

No target specified for emulator. Deploying to iPhone-X, 11.2 simulator

An error was encountered processing the command (domain=IXErrorDomain, code=2):
Failed to create IXPlaceholder for app bundle ID io.ionic.starter
An error was encountered processing the command (domain=FBSOpenApplicationServiceErrorDomain, code=5):
The request to open "io.ionic.starter" failed.
(null) was unable to service the request.
io.ionic.starter: -1
logPath: /Users/josh/Apps/Illume/illume/platforms/ios/cordova/console.log

注意：尽管出现了错误的最后一行，但日志似乎并不存在。
