Undefined symbol: nominal type descriptor for Swift.UInt8

Question

I am trying to run react native app in a Mac Mini with Apple M1 chipset.The project run well on intel based system but not running on M1. When I build I got following errors.

How can I fix this issue. I already tried adding a Swift file and bridge file. But that doesnt work.Please help me

Xcode version : 13.0, React Native Version : 0.64.2, iOS simulator 15, Mac OS: 11.4,

Answer 1

For those who still have this issue you can try out the following because it worked for me:

The link to the original post: https://dev.to/mngyuan/updating-react-native-projects-for-m1-mac-development-1mk4

We're going to exclude the arm64 architecture from our build. Under Targets, select your project -> Build Settings -> Excluded Architectures, and add Any IOS Simulator SDK : arm64 for both Debug and Release. Do the same for your Pods project.

If your project for some reason has VALID_ARCHS set, you'll want to remove that key from your project as well (and the Pods project) at this stage. We're very close to done, but the version of Flipper installed in your pods is likely not new enough to include the fixes for M1 macs. Open ios/Podfile and apply the following

• use_flipper!

• use_flipper!({ 'Flipper' => '0.75.0' })

And update your Pods

cd ios/

optionally reinstall all your Pods if you're still having issues

pod deintegrate

pod update

If you performed a build which failed, you might want to clear DerivedData like so

rm -rf ~/Library/Developer/Xcode/DerivedData/

Since am running react-native 0.64 I also had to add this to my pod file
