## README

f.lux-xcode
===========

This installs the f.lux iOS app on your device without requiring a jailbreak.
Learn more about f.lux at <https://justgetflux.com/>

Why isn't this in the app store?
--------------------------------

This app changes the color of all running apps on your phone, even when f.lux is
not directly open. Such functionality is not allowed in the [App Store Review
Guidelines](<https://developer.apple.com/app-store/review/guidelines/>), however
this type of app is possible.

How do I get this on my phone?
------------------------------

1.  Download (click releases above for file), then open with Xcode

2.  In the Project Editor, go to General > Identity > Bundle Identifier and
    append some characters to the identifier string to make it unique
    (anything but `com.justgetflux.iflux`) or you may get an error saying "An
    App ID with Identifier 'com.justgetflux.iflux' is not available. Please
    enter a different string."

3.  Plug in your phone

4.  Select your phone from the device menu (next to the "Play" and "Stop"
    buttons)

5.  Click "Play"

How does it work?
-----------------

There is an opaque, non-open-source app called `iflux` in this project. We trick
Xcode into signing and installing this app on your phone by:

1.  Building a dummy app "just an app"

2.  Splicing in the opaque binary during the build process

3.  Letting Xcode sign and install the app as normal

There are build errors
----------------------

We are building the binary twice, once using source code, and again by splicing.
This duplication is reported as an error by Xcode.
