The following build commands failed:
    CompileXIB MyApp/Classes/MainViewController.xib
(1 failure)
CordovaError: Promise rejected with non-error: 'Error code 65 for command: xcodebuild with args: -xcconfig,/Users/linuxplus/Public/Teste/platforms/ios/cordova/build-debug.xcconfig,-workspace,MyApp.xcworkspace,-scheme,MyApp,-configuration,Debug,-sdk,iphonesimulator,-destination,platform=iOS Simulator,name=iPhone SE,build,CONFIGURATION_BUILD_DIR=/Users/linuxplus/Public/Teste/platforms/ios/build/emulator,SHARED_PRECOMPS_DIR=/Users/linuxplus/Public/Teste/platforms/ios/build/sharedpch'

[ERROR] An error occurred while running subprocess cordova.

        cordova build ios exited with exit code 1.

        Re-running this command with the --verbose flag may provide more information.

Answer 1

This must be appearing in Xcode 10.x, I believe. In that case, it is because the build system has been changed in Xcode 10.x.

Try using below command:

• Build: ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"

• Run: ionic cordova run ios -- --buildFlag="-UseModernBuildSystem=0" --livereload

Reference: https://github.com/apache/cordova-ios/issues/407#issue-360392411

Hope this helps.

Answer 2

Try

ionic cordova build ios --prod --verbose -- --buildFlag="-UseModernBuildSystem=0"
