I am engaged on a ReactNative undertaking. A number of months in the past, I used iOS 16 simulator to check it. Labored nice. Finally for some causes, I switched to iOS 18 simulator, which additionally labored nice.
To save lots of disk area, iOS 18 simulator is eliminated. Then when working the undertaking once more:
yarn ios:dev
yarn run v1.22.22
$ react-native run-ios --udid F6BFC767-6B72-4ED2-92DF-C8AB9A3FB0A7
information Discovered Xcode workspace "AWESOMEAPP.xcworkspace"

error Didn't construct iOS undertaking. We ran "xcodebuild" command but it surely exited with error code 70. To debug construct logs additional, take into account constructing your app with Xcode.app, by opening AWESOMEAPP.xcworkspace.

Appears now the XCode workspace is hardwired to make use of iOS 18 (maybe I did some settings tweaking on XCode). Methods to make the undertaking runnable on iOS 16 simulator?
