Apple does not provide any supported way for you to check your app’s integrity. iOS already does that by default. https://forums.developer.apple.com/thread/52801 BlackBerry selling point, their DTEK and other measures to tell if a system's integrity is compromised. If it's been detected in the past, outside of a "hacked" Xcode posted and used briefly in China, I haven't heard "iOS says my system is compromised " either issues Ard caught before apps are posted to App Store, or is very rare. Something. I guess a failed update and)or having to wipe a phone to resolve is a symptom. What about storage system directory? Use to be common on desktop. Not supporting sdxc cards reduces problems, "infection" or just their higher incidence of failure and much slower medium. In the end, once my phone is set up I don't want to gave to redo or have it compromised and deal with passwords and such, even with 2FA enabled where it is supported. Considering iPhone 7S Plus, S8+, if Huawei P10 Plus - along with what I have now.
