Swift support for Facebook's Tweaks library.

(This is a part of MMMTemple suite of iOS libraries we use at MediaMonks.)

Quick example

We're trying to keep the spirit of super convenience Tweak's ObjC macros.

import MMMTweaks

// On startup:
#if DEBUG // Or any other condition when you want to have Tweaks enabled.

// Anywhere in your code, but better closer to the use site:
extension MMMTweaks {
    @objc static var shouldMockCookies: BoolTweak = {
        return BoolTweak(path: .init("Test", "Mocks", "Mock cookies"), defaultValue: false)

// Use site:
if MMMTweaks.shouldMockCookies.isOn {
    // ...

Both the original Tweaks library and this Swift shim are by default enabled whenever DEBUG macro and DEBUG Swift active compilation conditions are correspondinly defined in their targets.

To enable both libraries in configs where DEBUG is not defined you would need to define FB_TWEAK_ENABLED macro as 1 for Tweaks and add FB_TWEAK_ENABLED active compilation condition for MMMTweaks.

For example, you can enable both libs for non-Debug configs of your choice via a postinstall script in your Podfile:

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            if (target.name == "MMMTweaks" || target.name == "Tweaks") && (config.name == "<YourSpecialConfig>")
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'FB_TWEAK_ENABLED=1'
                config.build_settings['SWIFT_ACTIVE_COMPILATION_CONDITIONS'] ||= ['$(inherited)']
                config.build_settings['SWIFT_ACTIVE_COMPILATION_CONDITIONS'] << 'FB_TWEAK_ENABLED'
