Here is what Tim Cook has to say about sideloading apps on your iPhone

If iOS users are given a chance to sideload other apps similar to how Android allows, the security and privacy of iOS could be destroyed, Apple CEO Tim Cook has said. According to Cook, if Apple was forced to allow it, it may not be in the best interests of the user. It is to note that Apple has stringent privacy policies. The company has incorporated privacy nutrition labels and app tracking transparency for all Apple users where other apps will need to seek permission to track them.

Cook said all the privacy initiatives that they have built within the App Store and the security of the iPhone could be destroyed if Apple allowed users to sideload apps. “These things would not exist anymore except in people that are stuck in our ecosystem and so I worry deeply about privacy and security,” Cook said in an interview with Brut. Further, the Apple CEO claimed that Android has 47 times more malware when compared to iOS and then he attributed this to the Apple ecosystem which has been tied to “one” curated App Store. All apps on the Store are reviewed.
