React Native BUILD SUCCEED, but "No devices are booted."

Question

Here's my environment:

➜  AwesomeProject node --version
v6.3.0
➜  AwesomeProject npm --version
3.10.3
➜  AwesomeProject react-native --version
react-native-cli: 1.0.0
react-native: 0.29.0
➜  AwesomeProject watchman --version
3.0.0

Xcode version 7.3.1

I created the AwesomeProject described on: https://facebook.github.io/react-native/docs/getting-started.html#content

Then execute: sudo react-native run-ios

Here's what I'm getting:

Skipping bundling for Simulator platform

=== BUILD TARGET AwesomeProjectTests OF PROJECT AwesomeProject WITH CONFIGURATION Debug ===

Check dependencies

** BUILD SUCCEEDED **

Installing build/Build/Products/Debug-iphonesimulator/AwesomeProject.app
No devices are booted.
Launching org.reactjs.native.example.AwesomeProject
No devices are booted.

And the iOS iPhone 6 simulator is just showing a black screen.

Ideas?

Answer 1

When hitting react-native run-ios, one of the first lines printed to console, would be something like this (or similar)

Launching iPhone 6 (10.0)...

1. Boot the respective simulator manually
   • Go to spotlight search and start to type simulator
   • When spotlight presents the search result, choose the simulator app and hit Enter
   • Go to simulator app's menu: Hardwire -> Device -> iOS 10.0 -> iPhone 6 and select it
2. Reset
   • Go to simulator app's menu: Simulator -> Reset Content and Settings...
3. Retry
   • Command react-native run-ios again

Answer 2

I have just solved the same question.

First try using react-native run-ios instead of the sudo react-native run-ios.

Next try the following:

In file AppDelegate.m, change

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

To:

jsCodeLocation = [NSURL URLWithString:@"http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true"];

(This may be a security issue with iOS 9);

Next try to reset your env.

Answer 3

I have the same problem when first time to run react-native run-ios Try Hardware -> Reboot the simulator, and run it again.
