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 and delete derived data.
- Close XCode.
- Reopen project.
