You do not have the required file permissions

We exchange project files over a shared git repo on remote server and somehow I just lost write access to some files:

How to Autogenerate App Version Number from GIT

Application needs a version number, naturally. It's publicly used to identify, which version customer is using (and reporting bugs about).

However there is a very important technical reason to take good care of version number: if you want to update application, the new version number must be bigger than the old one. Sounds easy, yet again...

Let's check the documentation:

The Curse of Version Control

Version control is a MUST for any developer - but that doesn't mean you have to use an external version control system. The importance is in the idea and attitude instead of using any specific tool.

Last week we got a harddisk crash, removing SVN version control and TRAC project management from service. Regardless of that - and summer vacations causing delay in repair - work must go on. Was shocked to realize how much I had started to rely and depend on SVN as part of normal development cycle. Suddenly I was on loose ground!

Version control without a version control tool requires certain kind of routines:

• Think before you start doing anything
• Complete your thinking before you start doing anything
• Test your thinking before you start doing anything
• When thinking is done, start doing - don't procastinate

This time it's all about you. It's all in the mind. It's personal.

• Split the work into small enough parts which you can design, implement, test and release during one cycle
• Never start anything you can't complete during same session
• Make regular backups of your progress, even local ones
• Document what you plan to do and how you think you did it
• Automate anything you can

The less you have to keep in your mind, the better you can focus. The better you can focus, the faster you get results. The faster you get results, the easier it will be to fix them.

SVN Rollback is Backwards Merge

While debugging interesting side-effects, I decided to take a "shortcut" and rollback project sources to some earlier version. Just checking when the weird behaviour start to happen.

Found out that SVN rollback is actually a backwards merge - with the usual, expected and dreaded merge conflicts.

Successful rollback does not necessarily produce compiling code. You got to do rollback - to same version - couple times to catch all merge conflicts. Seems to depend on order of files.

Looking for SVN replacement.

Why doesn't my graphics change when I edit them

Problem with branching and merging is that graphics files might change physical location. Xcode won't complain anything at all, as long as it can find some copy of the file.

Check if you have several copies of same file e.g. under project root and inside classes folder. Find out which one is being used, remove the other one(s) and fix version control to contain only one copy of the file.

Agree common location for all graphics files, regardless if they are used only within one of several modules in project.
