Mastering Swift 2 Programming (Video 33)

The video tutorial addresses the issue of concurrent thread access disrupting code predictability. It introduces NSLock as a solution to coordinate thread operations and protect global data. The tutorial demonstrates implementing locks in code, highlighting the importance of unlocking to prevent deadlocks. It emphasizes efficient lock usage to minimize execution delays and concludes with testing the solution to ensure proper thread synchronization.
