When we try to publish a dev client build to tesflight, the build is rejected saying that it uses Non public APIs. I believe it would be useful to distribute the dev client via tesflight to make the distribution easy inside the team.
The exact error message is:
> ITMS-90338: Non-public API usage - The app references non-public selectors in MYAPP: _isKeyDown, _modifiedInput, _modifierFlags. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed.
