The most direct way to enable iPhone developer mode is to automatically trigger when connecting to a computer and running Xcode or other development tools. The methods to manually turn on include: 1. Connect your iPhone to your Mac and turn on Xcode. After selecting the device as the debugging target, the system will prompt you to enable developer mode; 2. Go to Settings > Privacy and Security, and try to click on certain menu items multiple times to trigger the hidden "Developer Mode" switch. Prerequisites include using iOS 16 or later, unlocking iPhone, having a Mac or supporting development tools. Notes include: Some functions are only available in developer mode, need to be reauthorized after restarting, it is not recommended to enable them for a long time, change the computer or reinstall the system and re-pair the device. If the option is not found, try updating the system and Xcode, replacing the data cable, or logging out of the iCloud account. If the conditions are met and the steps are followed, it will be successfully turned on.

The most direct way to enable iPhone developer mode is to automatically trigger it when you connect to your computer and run Xcode or other development tools. But if you just want to enable this mode manually (especially in iOS 16 and newer), here are some practical methods and notes.

Prerequisites for enabling developer mode

Before you start, make sure you meet the following basic conditions:

• Using iOS 16 or later
• iPhone is unlocked and works properly
• Have a Mac computer (for running Xcode) or use other supported development tools
• Have a certain understanding of Apple developer accounts (although it is not necessary, but it is helpful for subsequent operations)

If these premises are not met, the relevant options may not be seen or the activation may be successful.

How to manually enable developer mode

Starting with iOS 16, Apple has placed "Developer Mode" in settings as a standalone security switch, but it will not be displayed by default. You need to make it appear in a specific way:

1. Connect your iPhone to your Mac and turn on Xcode.
2. Select your device as the debug target in Xcode.
3. The system will prompt you to enable "Developer Mode" and click Confirm.

If you don't have development tools, you can also try the following ways to let the options appear:

• Go to Settings > Privacy & Security and scroll down to see if the Developer Mode switch appears.
• If you don't see it, try to click on a menu item multiple times (such as "File Transfer" or "Trust this Computer"), which can sometimes trigger the hidden option.

Once the switch appears, you can turn it on manually.

Things to note after opening

After turning on the developer mode, your iPhone will have some changes and restrictions, so you need to pay attention to:

• Certain functions such as sideloading apps, debugging web pages, etc. are available
• After each restart, some debugging functions may require reauthorization
• It is not recommended to enable it for a long time for ordinary users, as it may expose some unsafe options.

Also, if you change your computer or reinstall your system, you may need to re-pair the device to maintain developer permissions.

What if the developer option is not found?

Sometimes, even if all the conditions are met, there is no entrance to the "developer mode". You can try this now:

• Update iOS to the latest version
• Update Xcode to the latest stable version
• Try connecting the device with a different data cable
• Log in again after logging out of iCloud (very rare cases are valid)

If none of the above methods work, it may be that Apple is gradually pushing this function, so you can try again later.

Basically all this is it, the operation is not complicated, but it is indeed easy to ignore the details. As long as your device meets the conditions and follows the steps, you should be able to successfully enable developer mode.
