Swift ​

Point-Free together with their blog are great. Advanced Swift Book together with other books by objc.io are amazing too. Lickability Swift Best Practices Guide is a nice read.

SwiftLint is great.

OSS Swift CLI tools ​

• timeui - Command line profiling tool with stopwatch, cpu and memory usage.

Notes ​

• Avoid using AnyCollection.
• Swift collection types are value types, with copy-on-write to ensure performance as long as they aren’t shared.
