With Apple’s incoming changes to the requirements for use of IDFA and needing to request users permission via App Tracking Transparency popup which is incoming at some point in early 2021. Apps need to start to prepare to the incoming changes. So how do you add a IDFA App Tracking Transparency popup from a Unity app? At the moment there is no build in Unity method that will trigger the notification, There is however a preview package!
As Unity has started to move a lot of their tools and extension into packages within the Package Manager. It would be great if we could host our own re-usable unity packages within it, Well you can! Unity allows you to host your own collection of packages on our own server and have them show up in the package manager. (Note this is only possible from Unity 2018.3) With Unity just using a standard npm package system to host their packages we just need to setup our own server and get Unity to lookup that server for packages at the same time, We can do this but editing the project manifest.
