My Application works on Simulator but when installed on Phone it shows error

I developed an Application with the help of Firebase authentication video and my application as shown in the video works perfectly on the simulator with updations in firebase. But when I tried installing it on my phone it shows this error. I have tried everything possible and I need a solution to this problem as soon as possible.
Thank you :slight_smile:

hello maybe this can help?

also make sure you have added “permissions” in your info.plist. especially the “allows arbitrary load”
