Reviews summary
Practical grand central dispatch for ios
According to students, this course offers a clear and concise introduction to Grand Central Dispatch (GCD), making complex topics like concurrent programming in Swift approachable. Many found the hands-on coding and practical examples, such as the image downloading demo, highly effective for understanding and applying GCD principles, particularly for preventing UI blocking. While it provides a solid foundation for beginners and those looking to refresh their knowledge, some learners note it is too basic for advanced users and lacks deeper dives into complex scenarios or more challenging exercises.
Ideal for new or refreshing GCD knowledge.
"Excellent course for getting started with GCD."
"Perfect for brushing up on GCD or learning it from scratch. It is a solid introduction to GCD."
"It's a bit too basic if you already have some concurrency experience, but good for absolute beginners though."
Strong focus on practical, real-world use cases.
"I found the hands-on coding useful for understanding concurrent programming in Swift."
"The image downloading demo was a great practical application that helped solidify my understanding."
"I appreciate the focus on real-world use cases like image downloads. It gave me the confidence to use GCD effectively in my projects."
Simplifies complex GCD concepts effectively.
"The instructor explains complex concepts clearly with practical examples."
"I finally understand GCD after taking this course! The explanations of closures and concurrent vs. serial queues were spot on."
"This course clarifies the nuances of GCD, making it approachable. The short, focused lectures kept me engaged."
Pacing might be fast for complete beginners.
"Found it a bit too fast-paced for a complete beginner, especially the closure part. I had to rewatch some lectures multiple times."
"I struggled with the theoretical foundation. Probably better if you have some Swift basics down before starting this."
Could benefit from more advanced topics and exercises.
"I wished for more advanced topics or debugging strategies, but for an intro, it's very good."
"My main feedback would be to add more challenging exercises beyond just the image download."
"The course is too short and doesn't dive deep enough into complex GCD scenarios. If you want to master GCD, this is not for you."
