ignite: running react-native run-ios does not launch app

I’m trying to run the PizzaLocation app but When running react-native run-ios it outputs Build Succeeded but nothing launches. I’ve looked around online but haven’t had any luck finding anything.

I get the following output in terminal

** BUILD SUCCEEDED **



The following commands produced analyzer issues:
	Analyze Base/RCTModuleMethod.mm
	Analyze Modules/RCTUIManager.m
(2 commands with analyzer issues)

Installing build/Build/Products/Debug-iphonesimulator/PizzaApp.app
Launching org.reactjs.native.example.PizzaApp
org.reactjs.native.example.PizzaApp: 42784

And then in my other terminal window I see this, but nothing else happens from here.

Metro Bundler ready.

Loading dependency graph, done.
 BUNDLE  [ios, dev] ./index.js ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 100.0% (1974/1974), done.

Steps to reproduce

ignite new PizzaApp
- Andross selected
- No i18n
- No Animation
run react-native run-ios.

ignite doctor results:

I was able to get this working. It still does not work if I just use react-native run-ios but if I run with react-native run-ios --simulator="iPhone 6s" or specifying another iPhone type it works.

As @gdowens mentioned, I followed those steps and it worked for me rm -rf ios/build then running react-native run-ios --simulator

Having the same issue in xcode 10

me too. try this maybe, it worked for me before but now the problem appear again

Xode -> file -> project setting for « pre user build system » choose « legacy »

I’ve tried

setting all workspace/ project build and pre-build systems to “legacy”

deleting the build folder

running the run-ios with different specified devices

But every time my simulator opens, the app opens to the loading page, then crashes. It never gets pass the loading page.

But if I build the project from XCode everything works fine.

Any advice?

Did you figure out? I am having the same issue. it works with Xcode, but not in terminal (react-native run-ios)

Just going to put this here, because it comes up in search results and I’ve been trying to figure this out for several hours: If you are using react-native-splash-screen, make sure you do SplashScreen.hide() 🤦‍♂
