Info.plist indicates an iOS app, but submitting .pkg

Question

I'm getting an error trying to use Application Loader to upload a packaged electron app.

I use electron-packager to package the app with the mas (Mac App Store) platform. I then zipped up the output directory. When I try I to select this .zip file with Application Loader, it gives me this error.

Answer 1

You need to pack you .app file into a signed .pkg, which you can upload using Application Loader.

Use the following command to create a signed .pkg file:

productbuild --component YOURAPPNAME.app/ /Applications --sign "3rd Party Mac Developer Installer: YOURCOMPANYNAME (YOURTEAMID)" --product YOURAPPNAME.app/Contents/Info.plist YOURAPPNAME.pkg

For this to work, you'll need a Mac Installer Certificate, which you can generate from the Apple Developer website. When creating the certificate choose Mac App Store and then Mac Installer Distribution.
