Error while running ionic cordova build ios --prod

Question

I'm having this error while trying to deploy angular ionic app to ipa. After i run 'ionic cordova build ios --prod', these errors appear. Please help me to solve these errors. P/s: I'm using Ionic 4 and Xcode 9.2.

This is my project.pbxproj file:

// !$*UTF8*$!
{
    archiveVersion = 1;
    classes = {
    };
    objectVersion = 52;
    objects = {

Answer 1

try to use the latest version of Xcode.

1. ionic cordova platform remove ios
2. ionic cordova platform add ios
3. ionic cordova build ios

Make sure you have signed your app to right team and run pod install inside platform/ios if you use some custom plugin
