#Intro

Kotlin is a new programming language for the JVM. It produces Java bytecode, supports Android and generates JavaScript. The latest version of the language is Kotlin M5.3

Kotlin project website is at kotlin.jetbrains.org.

All the codes here can be copied and run on Kotlin online editor.

Let's get started.

Condensed iOS Human Interface Guidelines

Imperatives for AppStore approval

For iPhone app developers. Emphasis on getting the fastest app store approval. Everything stated as suggestion made into an imperative. When "violating" these imperatives, you can check for yourself what the caveats are. Generally speaking, deviating will more likely cause your app to be hung up in approval.

You can read this entire document in about 20 minutes. This is faster than reading and understanding the entire Human Interface Guidelines.

$ docker rmi $(docker images -q -f dangling=true)
