1. list all remote tags
git ls-remote --tags

2. delete local tag
git tag -d V_1_0_1

3. push tag deletion to remote
git push origin :refs/tags/V_1_0_1

4. tag local branch again

lucijafrkovic

1. git checkout -b branch_name tag_name
2. git push --set-upstream origin branch_name

or 
   git push -u origin branch_name

The driver situation with Apple Bluetooth wireless keyboards and Windows 10 is horrible, even with the latest BootCamp drivers. Fortunately, a workaround is available, if you're patient.

Pair keyboard once

1. Turn on the keyboard.
2. Press and hold Command + w until the keyboard light begins blinking, indicating the keyboard is ready to pair.
3. Use Windows Bluetooth settings to pair the keyboard, entering the same code (e.g. 123456 Enter) on both internal and external keyboards.

Pairing the keyboard is very trial and error. 9/10 times, Windows will complain that the keyboard is not available for pairing. Just keep trying.

In AppDelegate.m

#import <React/RCTLog.h>

Then in the didFinishLaunchingWithOptions function add:

RCTSetLogThreshold(RCTLogLevelInfo - 1);

React - Functional error boundaries

Thanks to React hooks you have now happily turned all your classes into functional components.

Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.

There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.

Proposed solution
