Flutter shows random error on iOS simulator, or build fails on iOS simulator

Question

I was building up a flutter project, and it shows random issues from yesterday.

Error:

Exception: Unable to get Xcode project information: 2022-05-21 11:24:21.526 xcodebuild[59059:315927] Requested but did not find extension point with identifier Xcode.IDEKit.ExtensionSentinelHostApplications for extension Xcode.DebuggerFoundation.AppExtensionHosts.watchOS of plug-in com.apple.dt.IDEWatchSupportCore 2022-05-21 11:24:21.527 xcodebuild[59059:315927] Requested but did not find extension point with identifier Xcode.IDEKit.ExtensionPointIdentifierToBundleIdentifier for extension Xcode.DebuggerFoundation.AppExtensionToBundleIdentifierMap.watchOS of plug-in com.apple.dt.IDEWatchSupportCore

How can I resolve this issue? My project got completely stuck on this and had implemented some random solutions like removing and installing CommandLineTools, etc. But no changes. Can anyone provide a solution for this?

Answer 1

I faced the same problem too. Tried updating everything(MacOS, Flutter version,[already using latest XCode]) to the latest version but did not work. But after adding "-lc++" to Other Linker Flags in my Build Settings, did the trick for me.
