How to Enable Developer Mode on iPhone (iOS 18–27) and Why Location Tools Need It

Since iOS 16, Apple hides developer features behind a switch called Developer Mode. Any tool that simulates your iPhone's location from a computer — Xcode, MyLocation for Mac, MagFone, iAnyGo — needs it on. Here is how to enable it and what it changes.

Turn it on

1. Open Settings → Privacy & Security.
2. Scroll to the bottom and tap Developer Mode. If you do not see it, connect the iPhone to a Mac once with a cable and tap Trust; the switch appears afterwards.
3. Turn the switch on and tap Restart.
4. After the restart, confirm with Turn On and enter your passcode.

What Developer Mode actually does

It allows a trusted computer to use development services on the phone: install test builds, inspect logs, and simulate location. It does not jailbreak the device, does not change how apps run, and does not void the warranty. Apple's own documentation describes it as a security feature that keeps these services off unless you explicitly want them.

Is it safe to leave on?

For most people yes. The theoretical risk is that a computer you trusted with a cable has more access. Only tap Trust on computers you own, and you can switch Developer Mode off again from the same screen whenever you like.

Next step: change your location

With Developer Mode on, connect the iPhone to your Mac and follow our guide to changing your iPhone location without jailbreak.
