Delta integrity flagging

So, for context, I want to install delta and give it a try. I got an iOS file for my iPhone 11 off of deltaexploits.gg but whenever I try to run the application, it provides me with the message: "This app could not be installed because its integrity could not be verified". I'm wondering if I have to root/jailbreak my phone to get it to run but Im not too keen on going down that rabbit hole. Any suggestions?
