How can I publish to the Apple app store my expo application?

I have finished to write a react-native application written with the help of expo SDK and I want to build my final .apk and .ipa for testing them with real devices.

During the development, I have used one iPhone 6 and one Galaxy S9 real devices using the expo application.

So far, I managed to build from Debian the signed apk but I didn't find a way to get an .ipa from my Debian linux system.

I can't have xcode installed but if needed I can rent a mac online and submit the ipa from there.

I have already followed those guides:

• https://docs.expo.io/distribution/building-standalone-apps/

• https://docs.expo.io/distribution/app-signing/

• https://customersupport.doubledutch.me/hc/en-us/articles/360001189514-iOS-How-to-Create-a-Distribution-Certificate

This guy says:

Is it possible…sure. The only thing a Mac is needed for is XCode for actually uploading your IPA to AppStore. I do not own a MAC personally, so I rent an online one via MacInCloud.

What are the steps to build an .ipa on expo?
