With no word on when we will see an official release of Xposed for Nougat, the PurifyOS team has gone ahead and modified the source of the framework to release an unofficial build of Xposed for Android 7.0/7.1 Nougat.
The unofficial framework has been confirmed to work on the OnePlus 3/3T running OxygenOS based on Android 7.1.1 Nougat. Other users running custom ROMs on their OnePlus 3T have also managed to get the framework working properly on their handset. However, the framework seems to be incompatible with Samsung devices for now, with owners of other devices also reporting bootloops and random app crashes post the installation. Since the framework is still in experimental stage and this is the first release, these issues should be sorted over time.
Due to the sheer number of underlying changes in Nougat compared to Marshmallow, many Xposed modules will first have to be updated to work properly with the OS as well.
It goes without saying that if you are new to the whole Xposed framework scenario, you really should not bother installing this unofficial release on your device.You should only flash this unofficial Xposed for Nougat build which is still a work in progress on your device if you know what you are doing.
You can download the unofficial build of Xposed framework for Nougat from here. If the framework linked in the post ends up putting your device in a bootloop, you can try the builds linked here.
It goes without saying that to install this unofficial release of Xposed for Nougat, your Android device must be rooted with a custom recovery like TWRP installed. Also, installing the framework will break SafetyNet which means that you will not be able to use Android Pay or any other app that checks for SafetyNet verification.
