+### Use System git instead of Xcode git
+
+<details>
+<summary>Explanation</summary>
+Xcode comes bundled with it's own version of git. In most cases this seems to work fine.
+
+In some scenarios I've found that Xcode is unable to bypass an authenticated proxy to fetch swift packages through ssh. In this case I run the following command to use my system git which will then also use my system in build ssh keys that I have registered against the ssh-agent.

+### Swift Package Manager - Cannot fetch as username does not match last
+
+This happens as there is a conflict between your last fetch of the package and new ones org id
+
+ie org-{some_number}}@github.com:auth0/JWTDecode.swift.git
+
+This needs to be changed to
+
+[git@github.com:auth0/JWTDecode.swift.git
