Hey Guys
Hoping someone can please help me understand what ARM64 build is and is it normal that this just appeared on my iphone 1day, super paranoid and am convinced someone is monitoring and tracking my phone usage.
iPhone X, iOS 11.4.1, null
ARM64 simply refers to the RISC architecture running on your iphone’s processor. Apple licenses chip architecture form the company “ARM” for use in their iOS device processors. ARM architecure supports both 32 bit and 64 bit processing - ARM64 specifically refers to the 64 bit instruction set. When an app developer produces an app in XCode, that app will require (as a dependency) the ARM64 instruction set.
So it is not only a perfectly normal thing to see on an ios device, it is an essential thing. Since iOS 11, iOS itself uses ARM64 almost exclusively.
