IOS build takes too long and never finishes for 0.75.2 version

IOS build takes too long and never finishes for 0.75.2 version

@SergenSiyli That error is because you are not running Metro.

in a separate terminal window, please run:

1. cd <path-to-your-project>
2. yarn start

Then relaunch the app or press the Reload button in the tab bar of the Red screen.

Build was successful if you ended up in that screen.

I solved the problem in the first item. I got a successful build on xcode. But the application still does not build with the npx react-native run-ios command. What can I do?

@SergenSiyli sorry to hear that the build time is taking too long.

Can you check a couple of things for me?

1. Can you try to build from Xcode and see if the build numbers increases or not?

2. Can you run bundle exec pod deintegrate and then reinstall pods? What I'm looking for is to understand whether you are using a prebuild version of Hermes or if you are trying to build hermes from source, as it is usually one of the pieces that takes most time (and that's why we are distributing prebuilds)

See the yellow line in the screenshot

Same system (Apple M2, macOS 14.6.1) and same issue, from 0.75.

duplicate of #46352, please focus all the comments on the previous issue.
We will work on this soon. Until then, please use Xcode to build if you are facing the issue.

Also, we use the same command on CI to build a sample project called hello world and I tested that yarn ios worked for me in a new project with 0.75.2. There might be something going on with your system configuration.
