About iOS Developer Mode

Developer mode was introduced with iOS 15. When developer mode is turned off, you cannot develop apps using the actual device, such as installing and debugging an app under development. This article explains how to turn on developer mode.

Why was the developer mode introduced?

The development function for developers allows them to install apps without going through the App Store. This is an essential function for app development, but for general users, it is a case where apps are installed in a way that they normally are not. The developer mode was introduced to prevent attacks that abuse these developer features.
