Reviews summary

Bridging swift to objective-c for ios

According to students, this course is a highly effective bridge for Swift developers seeking to understand Objective-C, particularly for navigating and working with legacy codebases. Learners praise the clear explanations of core Objective-C concepts, including syntax, message passing, and properties, and find the focus on language interoperability especially valuable. While it provides a solid foundational understanding and includes hands-on coding challenges, some learners feel the course offers a superficial overview and lacks the depth needed for advanced topics like memory management or complex real-world scenarios. It is generally considered a good primer but not a comprehensive guide to mastering Objective-C.

Includes hands-on coding challenges to reinforce learning.

"The hands-on coding challenges really helped solidify the concepts."

"The game building exercise was a good idea, but could have been more complex."

"The practical exercises reinforce the learning."

Strong emphasis on communication between Swift and Objective-C.

"I found the interop section especially useful."

"I particularly appreciated the focus on interoperability between the two languages."

"The course facilitates communication between the languages of iOS, which is practical."

Provides clear explanations of core Objective-C syntax and features.

"The explanation of message passing and categories was particularly clear."

"The course instructors did an excellent job of breaking down complex Objective-C concepts into digestible modules."

"The content on object instantiation and message sending cleared up a lot of confusion I had."

Effectively connects Swift knowledge to Objective-C, crucial for legacy projects.

"As a pure Swift developer, this course was invaluable for understanding existing Objective-C codebases at my new job."

"Absolutely essential for anyone working with mixed Swift/Objective-C projects."

"It's perfect for anyone needing to bridge the gap between Swift and Objective-C."

Some content or examples may be slightly dated or misaligned with recent Xcode versions.

"My main criticism is that some of the content felt a bit dated, although Objective-C itself is an older language."

"I also encountered a few minor issues with the provided code examples not always aligning perfectly with the latest Xcode..."

Provides a solid base but requires further study for full proficiency.

"It doesn't make you an Objective-C master, but it definitely gives you the confidence to read and navigate older projects effectively."

"It's a great starting point for transitioning or understanding legacy code, but don't expect to become an expert from this alone."

"I learned some things, but I wouldn't call myself proficient after completing it."

Serves as a primer but does not delve into advanced topics or real-world complexity.

"I felt some sections were a bit rushed, especially around memory management (ARC vs. Manual)."

"I found this course somewhat superficial. While it does explain the differences, it lacks the depth needed for real-world application."

"It doesn't go deep enough into real-world scenarios or advanced interoperability features."
