iOS Crash Dump Analysis
Faisal Memon has published a book, "iOS Crash Dump Analysis." This book is an example of the breadth and depth of his knowledge. This might be of interest if you are considering hiring, or contracting, Faisal through his company, Perivale Bluebell Limited.
In my second edition, I have updated the book to cover recent developments: Pointer Authentication, Apple Silicon, and Rosetta 2.
