For everyone concerned about the issue of shelf audit, in particular, explain:

Since this debug library calls the private APIs, the on-board review will not pass, so please remove it when submitting to AppStore.

The CocoaPods project only needs to set :configurations => ['Debug'] when adding a pod, which will only take effect in Debug mode.

The Swift Package Manager project can remove FWDebug from the Target when packaging the AppStore.

Installation tutorial

It is recommended to use CocoaPods or Swift Package Manager to install and automatically manage dependencies and environment configuration.


This debugging library supports Debug and Release environments. It is recommended that Debug mode be turned on. Podfile example:

platform:ios, '11.0'

target 'Example' do
pod 'FWDebug', :configurations => ['Debug']

Swift Package Manager

This debugging library supports Swift Package Manager. Please note that when packaging AppStore, please remove FWDebug from the Target. Package example:


 import FWDebug


This debug library uses a third-party library, thanks to all third-party library authors. Listed below:
