Error building for iOS

Hi everyone,

I have an app with the following info:

cli packages: (/Users/pisaris/projects/batler.io_new/batler.io-ionic-3/node_modules)

@ionic/cli-utils  : 1.16.0
ionic (Ionic CLI) : 3.16.0

global packages:

cordova (Cordova CLI) : 7.1.0

local packages:

@ionic/app-scripts : 3.0.1
Cordova Platforms  : ios 4.5.3
Ionic Framework    : ionic-angular 3.2.1

System:

ios-deploy : 1.9.2
Node       : v8.9.0
npm        : 2.15.12
OS         : macOS Sierra
Xcode      : Xcode 9.1 Build version 9B55

Environment Variables:

ANDROID_HOME : not set

Misc:

backend : legacy

When I run
ionic cordova platform add ios
everything works as expected.

However, When I run
ionic cordova build ios
I get the following error:

When I try to build the project using Xcode, I get the following:

Thanks in advance!

UPDATE:
It seems that the cordova-plugin-email-composer did the trick.
I removed it and the ninstalled it again and now it works…
But I don’t understand why…

Open the project in xcode. select provisioning profile and rebuild

ref https://github.com/ionic-team/ionic/issues/8464

@Saravkl Thanks for your reply.
My provisioning profile is set correctly. As I state in my post, the problem is not relevant with the provisioning profile, as it gets solved when I uninstall the cordova-plugin-email-composer, and install it again.
