Last week, Apple launched their developer beta for iOS 18.4. The update brings fresh changes to iOS, including Priority Notifications, a new Genmoji button, and additional supported languages. While it may be some time before iOS 18.4 is launched to all iPhone users, those curious to try out the new features can do so by installing the beta. However, doing so may cause some issues, so proceed with caution. How to install the iOS 18.4 developer betaIt's worth mentioning that there is some risk involved in installing a developer beta. The software can be unstable, as it is currently in testing and designed mainly for developers to make sure their apps are compatible with the latest iOS update. There are also likely bugs and glitches in this developer beta, which Apple is still working on fixing ahead of the public rollout. Those bugs can lead to data loss if you don't properly back up your device before installing the beta. If you have a idea of what you're doing and still want to try the new features, then go forth and have fun with the beta. However, it may not be a great idea to install the beta on your main iPhone.As mentioned, you should back up your iPhone before installing the iOS 18.4 beta on your iPhone. I recommend backing up with your Mac or PC using Finder or iTunes. While you can use iCloud to back up your iPhone, this can be tricky with betas: If your iPhone backs up to iCloud while running iOS 18.4, you won't be able to retrieve the data should you need to downgrade to the public iOS version. Backing up to your computer helps to ensure all your data from your iPhone stays intact. Next, you'll need to enroll your Apple ID in Apple's developer program. To do so, first head to the Apple Developer site, then select Enroll. Log in to your Apple ID, fill out your information, and agree to Apple's terms and conditions. While Apple has made it free to access developer betas, if you want to publish apps to the App Store, you'll still need to pay Apple's $99 yearly fee for full access to their developer program. Once you've backed up your iPhone and enrolled your Apple ID, you're ready to install the new developer beta. To install the beta, open Settings > General > Software Update. Below Automatic Updates, you should see an option for Beta Updates. Choose iOS 18.4 Developer Beta, then hit Back. Let iOS load for a moment, and you'll see an option to Download and Install the beta.
