Sideloading is not allowed per Apple rules and requires jailbreaking which comes with a list of caveats. So technically yes as a user I can side load but as a company providing apps it's not a realistic method of app delivery for the vast majority of use cases.

Patently untrue. This is — at best — a decade old retort.

Er, what? No.

According to you, I can jailbreak and sideload my iPhone 13? Or iOS 15?

Huh, doesn't appear so: https://www.getdroidtips.com/jailbreak-iphone-13-pro-max/

This is the second time you've made this claim on the thread. Nobody knows what you're talking about. What side loading are you referring to? You mean taking advantage of the dev loophole by asking users to build and sign your code every 7 days?

Happy to help my dude! Paste me an error or screenshot or a debug log?
