Description
At some point through my iOS “journey”, I must have disabled launching the packager. I think this happened at the same time I started linking react native exclusively through Pods. As a result, I have no React libs imported into the xcode project manually. I got rid of all of that and did it all through Pods, which has been working much better for linking other libraries!
Anyways, when I did that, it stopped launching the packager, so now I have to do it manually. I suppose I’m wondering A) how do I turn that back on? and B) is it possible the CLI should check and launch the packager itself if it was not launched during the build process?

Also having this issue after linking react native exclusively with Cocoapods during 0.59.5 update. In our case the issue is ALWAYS occurring in Debug. So please change the title of the issue as @noahtallen confirmed it is the same for him.
I found a workaround:
Yep, I can confirm moving the script into your app target’s build phases is the right thing to do
I think the react-native upgrade tool would need to add support for checking that there are no build phases which start the package
So, as per what I can see this is because the target
React
onPods
doesn’t have a start packager build phase as it does when you use it without pods.Without pods
With pods
I believe I can include the script to start the packager here by doing something like https://stackoverflow.com/a/20505234/4252781, I don’t have much experience with this so I am not sure.
@thymikee / @grabbou would you be able to point someone that can check if this is the right thing to do or not?
I tried to put the meat of the issue in the title 😉 @ou2s
cc @lucasbento as he’s working on similar field in #310. Feel free to check it out and suggest improvements!
That can work, you can see how the support works here: https://github.com/react-native-community/cli/blob/master/packages/platform-ios/native_modules.rb#L43-L62
I should get some docs on this out
cc @alloy @orta our lovely CocoaPods experts! 😃
@noahtallen: FYI I see that you mentioned that you couldn’t build it, I updated my local
cocoapods
to1.6.1
and did this to get it to run: https://github.com/CocoaPods/CocoaPods/issues/8091#issuecomment-421538684.
