Not very clear on the state of git options for iOS since I don't use that environment, but if there isn't app to your liking, you could probably host codeserver a web based instance of Visual Studio Code on the same machine running your gitlab/gitea, and manage your repo through that.
Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!
