App Extensions

When using PureLayout in an App Extension, you must define the preprocessor macro PURELAYOUT_APP_EXTENSIONS in the Build Settings of your App Extension's target to prevent usage of unavailable APIs.

If you do not do this, you will see an error such as:

'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.

To fix this:

1. In Xcode, select your Project
2. Choose the Target for your App Extension
3. Click Build Settings
4. Find (or search) Preprocessor Macros under Apple LLVM 6.0 - Preprocessing
5. For all build configurations (Debug & Release) add the macro PURELAYOUT_APP_EXTENSIONS=1

Now, when your App Extension target is selected, PureLayout will not use unavailable APIs.
