Blank app fails debug build - /Info.plist file not found - ios

Question

In a larger context I resorted back to creating a blank project and running my build commands.
Same error:
ionic start myApp blank
cd myApp
ionic cordova run ios --debug --target="iPhone-8" --consolelogs
ionic-app-scripts build --target cordova --platform ios

[ERROR] An error occurred while running subprocess cordova.
cordova run ios --debug --target iPhone-8 exited with exit code 1.
Re-running this command with the --verbose flag may provide more
information.
ionic --version

cordova --version
8.0.0 & #latest 8.1.1
XCode Version 10.0 (10A255) + build tools
macOS 10.13.6 - High Sierra. Mojave on a different machine fails the same.
The paths are adjusted if anyone wonders...
-------------- FIX --------------
Together with #DaveAlden's answer this is how I got it back up to do livereload without the bugs:
ionic cordova platform remove ios
sudo npm install -g ionic#3.20.0
ionic cordova platform add ios
open platform/ios/MyApp.xcworkspace
Follow instructions to fall back to legacy build system as on
https://github.com/apache/cordova-ios/issues/407
Run my build script, without the --buildFlag='-UseModernBuildSystem=0'

Answer 1

This problem is caused because Xcode 10 contains a new build system which is currently not compatible with cordova-ios#4 - see here.
The solution for now is to run Cordova with the --buildFlag='-UseModernBuildSystem=0' option to instruct Xcode to use the old build system, e.g.:
cordova run ios --debug --target "iPhone-8" --buildFlag='-UseModernBuildSystem=0'
Update: For my own convenience, I've wrapped this in a shell script:
#!/bin/bash
# Adds build flag to make cordova-ios#4 work with Xcode 10
cordova "$#" --buildFlag='-UseModernBuildSystem=0'
I saved this in a file called cordova-xcode10, made sure it's in the path and made it executable (chmod a+x cordova-xcode10), then I can just do:
cordova-xcode10 run ios --target "iPhone-8"
and it will work with Xcode 10

Answer 2

This problem is caused because of Xcode 10.
I resolved this issue by two ways.
ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"
Create a build.json file on root of project.
In build.json write below code.
{
"ios": {
"debug": {
"buildFlag": ["-UseModernBuildSystem=0"]
},
"release": {
"buildFlag": ["-UseModernBuildSystem=0"]
}
}
}
After that you can run these commands without any error.
ionic cordova build ios
ionic cordova run ios
ionic cordova run ios --target="iPhone-6s" -l

Answer 3

This worked for me
Open your workspace file, then File --> WorkSpace Settings
In shared Workspace settings, choose Build System: Legacy Build System.
Then run ionic cordova run -l

Update
I just found out that Cordova IOS 5.0.0 was released.
https://cordova.apache.org/announcements/2019/02/09/cordova-ios-release-5.0.0.html

Answer 4

This worked for me:
cd platforms/ios/cordova && npm install ios-sim#latest

Answer 5

This works for me:
cordova run ios --debug --target "iPhone-8" --buildFlag='-UseModernBuildSystem=0'

Answer 6

only add this flag in you command
cordova run ios --device --buildFlag='-UseModernBuildSystem=0' --verbose
work fine for me
