[MO] Debug Javascript on an iOS Device

Prerequisites

⚠️ The Ip mentioned is the one from your local network and not your router's ip on the internet

⚠️ Make sure you have reverted the changes after debugging to avoid build issues

Make sure both the device and computer are on the same network
Open your project in Xcode
In Libraries/React.xcodeproj/React/Base/RCTBundleURLPRovider.m
- Replace NSString *host = ipGuess ?: @"localhost";
- With your computer IP address (remove ipGuess if it poses problems): NSString *host = @"<your_computer_ip>";
In Libraries/RCTWebSocket.xcodeproj/RCTWebSocketExecutor.m
- Replace: host = @"localhost";
- With your computer IP address: host = @"<your_computer_ip>";
Verify signing by making sure you have obtained the signing certificate for debug first
