Integrating Xcode project and GitHub / Assembla

This short article will guide you step‑by‑step through creating Xcode project with local and remote Git repository (GitHub or Assembla) using SSH public/private keys authentication on remote side.

First part is really simple:

1. Open Xcode
2. Create new project: File → New → Project…
3. Check the “Create Git repository on My Mac” option during the project creation
4. Change some files and try commiting the changes, everything should work well

Now, proceed to remote

1. create repository
2. generate SSH keys to access repository:

   ssh-keygen -t rsa -f path/to/private/key

3. git remote add origin git@github.com:FurloSK/git‑test.git

1. generate SSH keys
2. Create config file in ~/.ssh/ directory:

   touch config

3. Open the file: open config
4. Paste this text into file, edit the IdentityFile path to match path to generated private key and save the file:

   Host github.com
   	HostName github.com
   	User git
   	IdentityFile "~/Path/To/Private/SSH/key"

5. Optionally, exclude files you do not want to be pushed to remote repository:
   1. Create .gitignore file: touch .gitignore
   2. Open the file: open .gitignore
   3. Supply line‑divided array of excluded files and directories
   4. Sample file for Objective‑C .gitignore file from GitHub is here: https://github.com/github/gitignore/blob/master/Objective-C.gitignore
   5. Finally, push last commited local changes to remote directory:
      1. in Xcode: Source Control → Push…
      2. in Terminal: git push ‑u origin master
