“Unable to install: integrity could not be verified”

The app file is fine — the iPhone did not accept the signature. This happens when the certificate is still being issued, was revoked by Apple, or an old version is left on the iPhone.

What to do

1. Check the certificate. Make sure your certificate is ready. If it is still being issued, wait a little.
2. Remove the stuck icon. If a grey icon with “Waiting” is left on the Home Screen, delete it.
3. Install again. Tap Install on the app once more.

Still not working?
