I am working on a project with another developer, the app is not on the App Store yet. We are getting Git merge conflicts because our accounts are not on the same development team. I tried adding the developer to the team in the developer portal but it only allows that for apps that are live in the store. How can we work on the same project without git conflicts?
If you have an individual developer account, you can’t add others to your team. If you have a company developer account, you can add others to your team in the developer portal. Note that that’s different from App Store Connect. Go to https://developer.apple.com/account to start, and then click the Membership tab to add people IIRC. You’ll end up sending them an invitation to join your team.
