How to Install Flux iOS 9.2 No Jailbreak Required
To install f.lux, you’ll need to sideload it on iOS. While this sounds complicated and scary to those of you unfamiliar with Xcode, but we’ll make the steps to install f.lux as simple as possible, all you’ll need is a free GoodNight project file, a free copy of Xcode which doesn’t require a jailbreak and will work on any firmware, including iOS 9.1, iOS 9.2 and iOS 9.2.1.
Download Flux for iOS 9.2 un-Jailbroken
Step 1. Download both the GoodNight project file (this app will provide f.lux capabilities on iOS 9.2) and the latest version of Xcode, which are both provided to download below.
iTunes, which you should update if your version is outdated.
GoodNight Xcode project on GitHub.
Xcode 7.x for Mac OS X, which can be obtained via the App Store.
Step 2. Plug your iPhone, iPad or iPod touch into your computer via a standard USB cable and ensure that the computer successfully recognizes your device (use iTunes to verify). Open the GoodNight.xcodeproj file inside the GoodNight-master folder you downloaded in the previous step.
Step 3. Change the middle segments of the primary bundle identifiers for the GoodNight app and the GoodNight widget targets under the General tab to something that’s easy to remember. For example, if you change the GoodNight app identifier to “com.flux.goodnight”, the corresponding identifier for the widget would be “com.flux.goodnight.GoodNight-Widget” – it’s important that you leave the final “.GoodNight-Widget” string in place for the widget’s identifier.
Step 4. For both the GoodNight app and widget targets, click on the capabilities tab, toggle App Groups if it isn’t already and click the plus button inside the App Groups section.
Step 5. If you have yet to sign in to Xcode, login with a regular Apple ID account. Next, provided you clicked the plus button in the previous step, you’ll be asked to specify a new app group. You must ensure that your custom group name matches that of your identifier (based on what we specified in the third step, it would be “group.com.flux.goodnight”).
Step 6. Uncheck the original app group, “group.com.adatech.goodnight” should be checked by default, and ensure that the same custom app group specified in step five exists in both the GoodNight app and widget targets’ capabilities tab.
Step 7. Click the arrow to expand the GoodNight project on the left-most pane inside of Xcode and navigate to the Shared > Supporting Files directory. Click on PrefixHeader.pch and modify the appGroupID to match the group you established when following the fifth step.
Step 8. Ensure that your device is selected in the upper left of Xcode (by default, it should say ‘iPhone 6S Plus’) and click the play button to the left of the device selection drop-down. To properly open the app once it’s installed, open the default Settings app on your device, tap on General > Device Management > Developer App ID and trust your Apple ID account profile.
Congratulations, after following these steps, you’ve successfully installed an app that will provide f.lux features on an un-jailbroken iOS 9.2 iPhone, iPad or iPod touch! Furthermore, the same steps (omitting steps 4-6) will allow you to install other non-official applications as well, provided you have their Xcode project files.
