Uploading new build to TestFlight for React Native with Expo
17 November 2020
This morning, I encountered a build issue during the release of my React Native application on iOS.
It’s not the first time and I think it’s coming from the last Xcode upgrade.
Here is how I solved the problem.
Update your cli to the last version
To identify if the problem is not coming from your machine you need to upgrade the expo cli tool:
npm install -g expo-cli
My error with expo upload:ios
When I want to release my build to production, I use these commands:
expo build:ios --release-channel production
expo upload:ios --latest
But today, the God of Cryptic Error Messages was on my side.
The call to the iTMSTransporter completed with a non-zero exit status: 1. This indicates a failure.
If you pay attention to the message, you need to use the Transporter.app
We recommend using Transporter.app instead of the expo upload:ios command if you have any trouble with it.
Fixing the issue and upload with Transporter
Transporter is a simple and easy way to deliver content on the Apple Store Connect. Here is a half automated workflow to speed-up the process. First, we want to log the download URL for the standalone iOS binary:
You can download it with a curl
curl -o archive.ipa “$(expo url:ipa)”
open the finder with:
Drag and drop your archive.ipa to the Transporter App:
You can start to roll-out to Production.
