This is disabled by default since it seems to break the terms of the iOS SDK agreement for iOS versions prior to iOS 8. It can be re-enabled in SDL_config_iphoneos.h.

Notes -- CoreBluetooth.framework
==============================================================================
SDL_JOYSTICK_HIDAPI is disabled by default. It can give you access to a lot
more game controller devices, but it requires permission from the user before
your app will be able to talk to the Bluetooth hardware. "Made For iOS"
branded controllers do not need this as we don't have to speak to them
directly with raw bluetooth, so many apps can live without this.
You'll need to link with CoreBluetooth.framework and add something like this
to your Info.plist:
<key>NSBluetoothPeripheralUsageDescription</key>
<string>MyApp would like to remain connected to nearby bluetooth Game Controllers and Game Pads even when you're not using the app.</string>
