Hi,
We have mobile application developed into IONIC 1. It is working fine with Android OS, but it is not working on iOS 12 devices. We are able to build an IPA file using XCode 10 with valid distribution certificate and provision profile. Once app is installed into iphone and open, it disappeared.
On simulator, I have tried with .app file, it is showing below log on service log service of an emulator.
UIKitApplication:{bundleId}
Program specified by service does not contain any valid architectures for this system.
services excited with abnormal code:78
