Enterprise Distribution not playing nice with iOS8 in Swift App

Question

I'm having issues running Enterprise builds onto iOS 8 devices with my swift app. It seems to be working fine if i use a non-enterprise account to code-sign. Is anyone experiencing this issue?

Here is a crash log that I am getting on an iOS device when attempting to run a build with an enterprise account to codesign:

Answer 1

All explained in details in this article :

https://www.airsignapp.com/ios-apps-using-swift-crash-when-signed-with-inhouse-certificate/

We can confirm that after create a new cert and .mobileprovision, no more issues.

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

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

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

Answer 2

I think Apple has already summarized it under Swift app crashes when trying to reference Swift library libswiftCore.dylib

Refer to my previous answer.
