How to Turn On iPhone Developer Mode [Video]

With iOS 16 and later, app developers must enable the iPhone Developer Mode feature to use their device with Xcode. Apple says the new Developer Mode is designed to protect users from inadvertently installing potentially harmful software, and reduces attack vectors exposed by developer-only functionality.

When you first connect an iOS device to your Mac, Xcode will show it as an "Unavailable Device". If you attempt to build and run a project, Xcode will inform you that the destination is not valid. Enabling developer mode will resolve this.




Here's how...

ENABLE DEVELOPER MODE ON IPHONE

Step One

Tap to open the Settings app from your home screen, then choose Privacy and Security from the Settings menu.

Step Two

Tap Developer Mode from the privacy and security menu, then toggle the Developer Mode switch to the ON position.

Step Three

Choose Restart from the alert that appears, to reboot your device.

Step Four

Your iPhone will now reboot. Once the restart has completed, a pop up window appears prompting you to enable developer mode. Tap Turn On to turn on developer mode.


Now that you have enabled developer mode, your device will now be available to Xcode. Once its debug symbols have been fetched, it will be ready to build and run locally installed apps.

IMPORTANT NOTES

● After you have enabled Developer Mode the first time, Xcode doesn’t ask again unless you disable Developer Mode or you restore the device. You can Build and Run from Xcode without further prompts to enable Developer Mode.
● To turn off the Developer Mode option, simply return back to Settings > Privacy & Security > Developer Mode and turn off the developer mode toggle.
