iOS App with Swift crashes due to Certificate issue

Below was what the crash report indicated. 

[deny-mmap] mapped file has no team identifier and is not a platform binary: /private/var/mobile/Containers/Bundle/Application/B7B2BE25-BEE1-4DD0-B6BD-2BF4E4932862/TestApp.app/Frameworks/libswiftCore.dylib

 We found origins that caused this issue, related to a missing attribute in “Subject” field InHouse Certificates :

    It was

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, O=Company Name, C=FR

    And now we can find a OU field in new certificates :

    

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, OU=269J2W3P2L, O=Company Name, C=FR

The OU, which stands for organizational unit should be mandatorily present in the certificate it appears.
