Watched Swift: Loading Images Asynchronously and storing with NSCache and NSURLCache. I didn’t know Link Conditioner exists for macOS. I always used one in OS. Also I have never used NSURLCache. I only used NSCache previously.

Read NSHipster’s Network Link Conditioner.

Read NSHipster’s As We May Code. Understood nothing. Then read Cross-Pollination where also understood very little.

Read Understanding Swift’s CharacterSet. It’s brilliant! Has a code to print all characters from any character set. It’s eye opener to print out CharacterSet.decimalDigits. That’s what I always wanted to point my colleagues.
