Install claimed to have succeeded, but application could not be found on device
I ran into the same issue while testing a Cordova app on iOS 13 via XCode 11 Beta 4. Building via the legacy system solved it (File > Workspace Settings... > Build System > Legacy Build System).
Hope it helps
I solved this problem doing tipical project clean steps:
- Product -> Clean.
- Window -> Projects -> Select your project anddelete derived data.
- Close XCode.
- Reopen project.
This is a code signing issue. Xcode 11 requires you to add the "Apple Development" certificate to your development provisioning profile that they automatically added to your certificates and profiles. Add that certificate to your profile, redownload your development profile and vwala.
