Ionic 4 with capacitor: xcodebuild fails with manual signing process - ios

Question

I'm trying to build the iOS version of an Ionic app which uses capacitor in my continuous integration system (Azure).
This is the output I get:
/usr/bin/xcodebuild -sdk iphoneos -configuration Release -workspace /Users/runner/runners/2.160.1/work/1/s/ios/App/App.xcworkspace -scheme App build CODE_SIGN_STYLE=Manual CODE_SIGN_IDENTITY=iPhone Distribution: <not_displayed> (ENT) PROVISIONING_PROFILE=5254b426-4af0-45e7-aeab-ec63a303d250 PROVISIONING_PROFILE_SPECIFIER=
Build settings from command line:
CODE_SIGN_IDENTITY = iPhone Distribution: swiss1mobile ag (ENT)
CODE_SIGN_STYLE = Manual
PROVISIONING_PROFILE = 5254b426-4af0-45e7-aeab-ec63a303d250
PROVISIONING_PROFILE_SPECIFIER =
SDKROOT = iphoneos13.1

I've been searching a lot but no luck. Any clue?

A little workaround fixes this problem. I found this issue in Github for a similar error caused by an update in cocoapods. I find it a bit hacky, but it works. I'm not sure if Azure should fix its xcode task to avoid these errors, but for now, this is good enough.
So the fix is just adding this code to the Podfile:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['EXPANDED_CODE_SIGN_IDENTITY'] = ""
config.build_settings['CODE_SIGNING_REQUIRED'] = "NO"
config.build_settings['CODE_SIGNING_ALLOWED'] = "NO"
end
end
end
This way the pods don't have to be signed, and the error is not shown anymore and the app is built.
