[ANNOUNCEMENT] Status of Xcode 10 support

[dpogue]

A few issues have started to come in regarding the state of Cordova projects on Xcode 10. This is a rough summary of the situation:

Xcode 10 uses a new build system by default (previously available on an opt-in basis in Xcode 9). The cordova-ios project structure is not compatible with this new build system and results in failures.
Officially, we do not claim to support Xcode 10.

Currently the best workaround is to opt-out of the new build system:

• If you're building on the command-line, you can specify --buildFlag="-UseModernBuildSystem=0":

  # Cordova CLI
  cordova run ios --buildFlag='-UseModernBuildSystem=0'
  cordova build ios --buildFlag='-UseModernBuildSystem=0'
  
  # Ionic CLI
  ionic cordova run ios -- --buildFlag="-UseModernBuildSystem=0"
  ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"
  

• If you're building with a build.json config file, you can add the following under the iOS release or debug config:

  "buildFlag": [
    "-UseModernBuildSystem=0"
  ]

• If you are opening the project in the Xcode IDE, you need to change the build system in Workspace Settings to "Legacy Build System"

  Xcode example

  

  Thanks kitolog for the screenshots!

We're going to investigate what's required to make cordova-ios compatible with the new build system, and hope to include that in the next major version (cordova-ios@5.0.0).

Just note here that the build.json file should look like this :

  "ios": {
    "release": {
      "buildFlag": [
        "-UseModernBuildSystem=0"
      ]
    }
  }

not

  "iOS": {
    "release": {
      "buildFlag": [
        "-UseModernBuildSystem=0"
      ]
    }
  }

like "mentioned" in the previous comment ;p

ERROR ITMS-90174: "Missing Provisioning Profile - Apps must contain a provisioning profile in a file named embedded.mobileprovision."

is there a workaround ?

[aceoliver]

@neofuture I am also encountering this after upgrading to XCode 10

[janpio]

Then open an issue please that has all available information on these failures @neofuture and @aceoliver. Thanks.

@dpogue Thanks! The answer solved my problem.

Is this ALL you guys needed to do? Nobody kept getting these errors?

[09:22:43]: [Transporter Error Output]: ERROR ITMS-90087: "Unsupported Architectures. The executable for TheApp.app/Frameworks/Sentry.framework contains unsupported architectures '[x86_64, i386]'."

[09:22:43]: [Transporter Error Output]: ERROR ITMS-90209: "Invalid Segment Alignment. The app binary at 'TheApp.app/Frameworks/Sentry.framework/Sentry' does not have proper segment alignment. Try rebuilding the app with the latest Xcode version."

Edit: Sorry, I just realized these are Sentry's issues.

@sambegin Thanks for the workaround. Where is this build.json file is present in the app directory structure?

[jeffreyramia]

Btw this worked for me:
ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"

[tanvishah-syn]

@jeffreyramia with the help of your answer I am able to build an app but whenever I am trying to emulate it gives me an error as "platforms/ios/build/emulator/demo APP.app/Info.plist file not found.
[ERROR] An error occurred while running subprocess cordova."

If you use pure cordova ios, you can run like:

cordova run --target='iPad-Air-2' --buildFlag='-UseModernBuildSystem=0'
