Learn how to enable iOS developer mode on iOS 16 and above to run internal distribution builds and local development builds.
On devices running iOS 16 and above, you will need to enable a special OS-level Developer Mode setting before you can run internal distribution builds (including those built with EAS) or local development builds installed on the device.
To enable it, you do not need to connect the device to a computer or use Xcode.
This does not apply to builds signed using enterprise provisioning, nor to any builds installed on an iOS Simulator.
Follow the instructions below (once per device).
Install the build on your device and press the app icon.
In the Settings app, navigate to Privacy & Security > Developer Mode.
Enable the toggle. You will receive a prompt from iOS to restart your device. Press Restart to do so.
After the device restarts, unlock your device; a system alert should appear. Press Turn On and then, when prompted, enter your passcode.
Developer Mode is now enabled, and you can now run internal distribution builds and local development builds.
You can turn off Developer Mode at any time, but note that you'll need to follow this same process again in order to re-enable it.
