Fresh React Native Project Fails on IOS build (M1 MacBook)

Solution for Fresh React Native Project Fails on IOS build (M1 MacBook)
is Given Below:

I created my first react-native project and I started metro just fine. But When I try to run IOS it fails to build. Any suggestions on what I should check?

  • latest Xcode installed
[email protected] TheGlobalDoctor % npx react-native run-ios
info Found Xcode workspace "TheGlobalDoctor.xcworkspace"
info Building (using "xcodebuild -workspace TheGlobalDoctor.xcworkspace -configuration Debug -scheme TheGlobalDoctor -destination id=845FA08B-2299-4B05-B9C9-207405392A77")
error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening TheGlobalDoctor.xcworkspace.
Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -workspace TheGlobalDoctor.xcworkspace -configuration Debug -scheme TheGlobalDoctor -destination id=845FA08B-2299-4B05-B9C9-207405392A77

Xcode Failed Build error:

fatal error: module map file '/Users/karar/Library/Developer/Xcode/DerivedData/TheGlobalDoctor-axdadhlgtbbtzcabxyzzteupuwlt/Build/Products/Debug-iphonesimulator/YogaKit/YogaKit.modulemap' not found 1 error generated.

I had a similar issue. You can start XCode using Rosetta to circumvent the problem for now.
To do so open ‘Applications’ and find XCode. Open it’s context menu and select ‘Get Info’. In the info view, make sure the “Open using Rosetta” checkbox is checked.

(Thx to Karthik posting the solution in his blog)
