Apple is expected to introduce iOS 27 in September 2026. If you are a developer, tester, or advanced user and preparing your device for the upcoming beta cycle, the most important setting for app testing and sideloading is Developer Mode.
Searching for how to enable TamperMonkey developer mode on iOS 27 beta, or simply want to know how to enable developer mode in iPhone settings before the beta arrives, this guide covers everything you need to know.
Developer Mode is a special iPhone setting introduced by Apple for developers and advanced users. With Developer mode, you can:
If you plan to test beta apps, use development tools, or want to experiment with app configurations on iOS 27 beta, enable developer mode iOS first.
Before installing any beta version, it's important to prepare your device carefully.
Beta software sometimes contains bugs, app crashes, battery drain, or performance issues. Always create a full backup using iCloud or Finder before updating.
Apple has not officially confirmed the supported devices for iOS 27 yet. Check Apple's official announcements once the beta is released.
If you use Xcode for app testing, make sure your Mac is running the latest available version.
Beta installations sometimes fail unexpectedly. Users commonly experience:
Troubleshooting with Tenorshare ReiBoot can resolve all the update issues.
There are two methods to enable developer mode on iOS directly on an iPhone or with a Mac running Xcode. The exact interface for iOS 27 can be changed slightly after release, but based on Apple's current workflow, the process should remain similar.
If the feature appears automatically when you install a development app, follow these steps:
Use Xcode or another trusted development environment to install a testing app on your iPhone.
Go to "Settings" and select Privacy & Security. Toggle Developer Mode ON. Your iPhone will ask you to restart the device.
After rebooting, unlock your iPhone and tap on "Turn On" when the prompt appears. Enter your passcode if needed. Developer Mode should now be enabled.
After updating to iOS 27 beta, some users may find that Developer Mode is missing from Settings. Normally, you can go to Settings > Privacy & Security > Developer Mode to turn it on. However, on some iPhones, especially after a beta update, this option may not appear right away.
If you are searching for how to enable developer mode iPhone on iOS 27, Tenorshare iCareFone is an easier solution. It can help trigger the hidden Developer Mode option, so you can enable it on your iPhone without using Xcode.
Download and install Tenorshare iCareFone on your PC or Mac. Then connect your iPhone to the computer with a USB cable.
After your iPhone is connected, open iCareFone and click the edit button, represented by a pen icon, next to the Quick Access section on the home page. Then add the Developer Mode tool to Quick Access.
Click the Developer Mode tool in iCareFone. Then open the Settings app on your iPhone and go to Privacy & Security.
Scroll down to find Developer Mode. Turn it on and tap Restart when prompted.
After your iPhone restarts, a pop-up window will appear. Tap Turn On again and enter your device passcode to confirm. Once completed, Developer Mode will be enabled on your iOS 27 device.
This method is especially useful when you meet the iOS 27 beta developer mode missing issue and cannot find the option in Settings. With iCareFone, you can quickly enable developer mode iPhone without going through a complicated developer setup.
If the option does not appear automatically, you will need to connect your iPhone to a Mac.
Use a Lightning or USB-C cable to connect your iPhone to your Mac. Now tap on "Trust this Computer" and enter the password if asked.
Launch Xcode and go to Window > Devices and Simulators. Under Device search for your iPhone. Now go to Settings > Privacy & Security > Developer Mode. Turn it ON and restart your device.
