How to upload to App Store from command line with Xcode 11?

With Xcode 11 as command line tools, to validate or upload an ipa, replace altool with xcrun altool:

xcrun altool --validate-app --file "$IPA_PATH" --username "$APP_STORE_USERNAME" --password @keychain:"Application Loader: $APP_STORE_USERNAME"

xcrun altool --upload-app --file "$IPA_PATH" --username "$APP_STORE_USERNAME" --password @keychain:"Application Loader: $APP_STORE_USERNAME"

You can now also use a new app from Apple called "Transporter" that is a replacement for Xcode application loader.

At least as of of Xcode 11, this can be done very easily and directly with xcodebuild, as part of the export workflow. Just create an exportOptions.plist file that specifies "upload" for the "destination" key and "app-store" for the "method" key. Here's an example, but of course tune to your needs:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>compileBitcode</key>
        <true/>
        <key>destination</key>
        <string>upload</string>
        <key>method</key>
        <string>app-store</string>
        <key>provisioningProfiles</key>
        <dict>
                <key>YOUR_BUNDLE_ID</key>
                <string>YOUR_PROFILE_NAME</string>
        </dict>
        <key>signingCertificate</key>
        <string>YOUR_CERT_NAME</string>
        <key>signingStyle</key>
        <string>manual</string>
        <key>stripSwiftSymbols</key>
        <true/>
        <key>teamID</key>
        <string>YOUR_TEAM_ID</string>
        <key>thinning</key>
        <string>&lt;none&gt;</string>
</dict>
</plist>

Once you have that, the command to upload an archive to app store connect is very simple, using the xcodebuild exportArchive command:

    xcodebuild -exportArchive \
               -archivePath PATH_TO_APP_ARCHIVE \
               -exportPath OUTPUT_PATH \
               -exportOptionsPlist exportOptions.plist

If you're wondering where your PATH_TO_ARCHIVE is, first just use the xcodebuild archive command, e.g.:

    xcodebuild -sdk iphoneos \
               -workspace myWorkspace.xcworkspace \
               -scheme myScheme \
               -configuration Release \
               -archivePath PATH_TO_ARCHIVE archive

Use command line tools,

xcrun altool --upload-app -f path -u username -p password

If your apple account use TWO-FACTOR Authentication , your password would be wrong , you need to go to https://appleid.apple.com/account/manage "Security - Generate Password" to get the password

If you get other wrong , you could add --verbose to print detail errors log, just like

xcrun altool --upload-app -f path -u username -p password --verbose
