I am engaged on a ReactNative mission. Just a few months in the past, I used iOS 16 simulator to check it. Labored fantastic. Ultimately for some causes, I switched to iOS 18 simulator, which additionally labored fantastic.
To save lots of disk area, iOS 18 simulator is eliminated. Then when working the mission once more:
yarn ios:dev
yarn run v1.22.22
$ react-native run-ios --udid F6BFC767-6B72-4ED2-92DF-C8AB9A3FB0A7
data Discovered Xcode workspace "AWESOMEAPP.xcworkspace"
data Launching iPhone 14 Professional Max (iOS 16.0)
data Constructing (utilizing "xcodebuild -workspace AWESOMEAPP.xcworkspace -configuration Debug -scheme AWESOMEAPP -destination id=F6BFC767-6B72-4ED2-92DF-C8AB9A3FB0A7")
error Didn't construct iOS mission. We ran "xcodebuild" command nevertheless it exited with error code 70. To debug construct logs additional, think about constructing your app with Xcode.app, by opening AWESOMEAPP.xcworkspace.
Command line invocation:

Appears now the XCode workspace is hardwired to make use of iOS 18 (maybe I did some settings tweaking on XCode). Easy methods to make the mission runnable on iOS 16 simulator?
Simply tried to wash the construct folder: Product -> Clear Builder. Noticed this message:
Why? Is having the newest iOS simulator put in is a should?
