Effective Test Automation in iOS Development

Test automation is probably the single most important factor within an agile software project.

Adventures in iOS Programming: Self-Sizing Cells

The other day, I was talking with BiTE CTO Brant about what we’d been up to lately in our iOS programming endeavors. I suggested that it might be interesting if your computer had a way to quantify how much time you spend on different sorts of programming task in the course of developing a project. …
