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

Thanks, @dpogue
I was really wondering about the workaround. Hope to fix it soon!
Cheers

is this why im getting this issue

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

is there a workaround ?

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

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

@dpogue Thanks! The answer solved my problem.

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

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

@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'

@PeterStegnar I won't be run because info.plist not present in the /build directory.

Yes this happen if you are using new build system. If you say to compiler to build legacy build then it is OK. All you need to do it so use:

--buildFlag='-UseModernBuildSystem=0'

Just do document what I'm seeing
Build with no command seems to just stop in the middle of it. It seems like its trying to build for some large of phonesxs default.

Build with the new command
ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"

Seems to build just fine and was able to push a version to the phone.

For ionic I see a build.json file. I add the following to it.

{  
"ios": {
    "debug": {
      "developmentTeam": "898989",
      "buildFlag": [
        "-UseModernBuildSystem=0"
      ]
    },
    "release": {
      "developmentTeam": "89989898",
      "buildFlag": [
        "-UseModernBuildSystem=0"
      ]
    }
  }
}

It seems to look at the build.json, either I don't have it setup right or something because its not using the command.

Code Signing Error: Automatic signing is unable to resolve an issue with the "APP NAME" target's entitlements. Automatic signing can't add the aps-environment entitlement to your provisioning profile. Switch to manual signing and resolve the issue by downloading a matching provisioning profile from the developer website. Alternatively, to continue using automatic signing, remove this entitlement from your entitlements file and its associated functionality from your code.
Code Signing Error: Provisioning profile "iOS Team Provisioning Profile: com.app.dev.app" doesn't include the aps-environment entitlement.
Code Signing Error: Code signing is required for product type 'Application' in SDK 'iOS 12.0'

I don't think that error surprise us. But not sure why adding the command to build.json file doesn't seem to work.

That error about code signing is unrelated to the new build system.
In your build.json you are not including the flags to use automatic provisioning, but you are also not specifying which provisioning profile to use. This probably wouldn't work in Xcode 9 either.

Okay, so I don't have the build.json file really setup to be used. Other values would need to be in there. For now just have to use the command line.

Is there any plan to support the modern build system?

Is there any plan to support the modern build system?

Yes, in the next major version, which we're currently working on. But we don't have a timeline for release beyond something before the end of the year.

@PeterStegnar Thanks I am able to build and emulate app on ios with the help of --buildFlag='-UseModernBuildSystem=0' this flag. Does anyone have documentation link for this flag?
I have to explore it more.

Is anyone having trouble using the --livereload flag with --buildFlag='-UseModernBuildSystem=0'? If so any ideas how to enable livereload

--livereload is not part of Cordova. You will probably want to ask this question over at http://forum.ionicframework.com/ or one of their repositories, possibly Ionic CLI.

@andrewmcewen Yes: I get a lot of starting messages without the build actually starting.

For a moment I was about to say "I can't believe Apple is going to force all development to Xcode 10 to support iOS 12.1 when there are so many outstanding issues." Then I realized..."Oh, its Apple...duh".

I too got the above March 19th WARNING when I submitted a new version of my app yesterday. If I upgrade to Xcode 10.1 to 'officially' support iOS 12.1, then what is the minimum version cordova-ios needed? I am currently on 4.5.4. If I move only to 4.5.5, what are the big gotchyas for trying to develop for 12.1?

It's all just a bunch of Rotten Apples. I LOATHE developing for iOS.

Keeping this ticket open until platform release.

Is there any update regarding this issue? Using the UseModernBuildSystem workaround each run makes Cordova to kill and lunch the emulator.

I tried the tutorial but getting the error:
[ERROR] An error occurred while running subprocess cordova.

Can someone help me?

Anyone encountered wrong "text encoding" issue for localizable.strings, which now Xcode 10.1 doesn't allow to build project before fixed?

At first, I thought it's due to a corrupted file, then suspected a resource of third-party plugin, but seems any localizable.strings being added into ios platform are deemed to have wrong text encoding where their contents are actually UTF-8 (plain text file, English words). This can be fixed through Xcode but it's blocking me to auto-build using command line.

[ERROR]
could not decode input file using specified encoding: Central European (ISO Latin 2), and the file contents appear to be encoded in Unicode (UTF-8)

Any one can help please?

Hello,

Does anybody know when cordova-ios 5.0.0 will be available for production? What is the current state?

I'm obviously asking because of apple's decision to shutdown anything prior to xcode 10 soon. I'm not involved in the cordova-ios project. So any information would be appreciated.

If you happen to know how the process works for releasing a cordova version (for example, what determines if a build is production ready or not and where I can find such stats), I would greatly appreciate it.

Thank you

@majdi21 It looks like it has been released now 5.0.0

It is still currently in the middle of the release process. It is recommended to wait until it is released on NPM.

@erisu My apologies. I assumed once it was tagged here we were good to go.

@dpogue you sir won the internet today!!!

Not to tick anyone off or insult anyone or the effort into making 5.0.0 happen, but how tested is the latest release - or can we all ignore my inquiry and just thank Apple for forcing us into bleeding edge?

For the record....its stuff like this...and a gazillion other things about Apple that tick me off. Nothing but a bunch of rotten Apples.

cordova-ios@5.0.0 is now officially released to NPM.

Here is also the Cordova iOS 5.0.0 Release Blog Post.

Thanks to everyone involved!

Good to hear. Thanks. It is really appreciated for your hard work.

I'm slightly confused about the release. Does it mean if I update to 5.0.0, using UseModernBuildSystem=0 is no longer required?

Thanks!

That's correct

@dpogue It seems as though setting UseModernBuildSystem=1 is still behaving like it used to, even after upgrading to 5.0.0. Can you show a sample output of a build process using the new build system?

After adding cordova-ios@5.0.0, can't add onesingal plugin.

It shows this issue:

    Re-running this command with the --verbose flag may provide more information.

Firstly, [!] You cannot run CocoaPods as root.
Secondly, Cocoapod support was refactored in cordova-ios 5.0.0, which is one of the reasons it's a major version bump. Some plugins might not (yet) be compatible with it.

I'm going to lock discussion on this issue, since it is closed. Please open new issues for problems that you find with cordova-ios@5.0.0.
