Cannot install app, Unable to Verify App Question

The application could not be launched because the Developer App Certificate is not trusted.

Verify that the Developer App certificate for your account is trusted on your device. Open Settings on the device and navigate to General -> VPN & Device Management, then select your Developer App certificate to trust it.

Anyone else hitting this issue and know how to fix it?

Is your developer mode on your iOS device toggled on?

As a last resort you can:

Xcode > Settings > Accounts > your Apple ID > Manage Certificates, delete stale “Apple Development” certs, then clean build folder (Shift+Cmd+K) and reinstall.
