Intro to Python

Assumes a start with Python 3.6. Python 2.7 is end of life in 2020, so new projects should avoid it.

Important PEPs

PEPs (Python Enhancement Proposals) are how new features are added to the language and are very useful for learning why things are the way they are.

Some also offer style guidance.

Swift Don'ts

• Don't add code cruft. Avoid parentheses around conditions in if-statements or with the return keyword. Don't add semicolons except where syntactically demanded in statements or to separate statements on the same line.
• Don't use ALL_CAPS; use camelCase
• Don't fight type inference. Use enumeration prefixes, self-references, and class names (with constructors) only when necessary or to clarify coding intent.
• Don't use var when let is appropriate, especially for properties. The compiler better optimizes let statements for items whose values will not change during their lifetime. For example, Apple writes, "It is good practice to create immutable collections in all cases where the collection does not need to change. Doing so enables the Swift compiler to optimize the performance of the collections you create."
• Don't use classes when structs will do. Use class

AlamofireSoftwareFoundation

Last week, a number of publications ran a story about 1,000's of apps allegedly being vulnerable due to an SSL bug in AFNetworking. These articles contain a number of inaccurate and misleading statements on this matter.

We are publishing this response to clarify and correct these statements.

Background Information

For those not familiar with AFNetworking, here are some relevant details about the library for this story:

• AFNetworking is an open source, third-party library that provides convenience functionality on top of Apple's built-in frameworks.
• One component of AFNetworking is AFSecurityPolicy, which handles authentication challenges according to a policy configured by the application. This includes the evaluation of X.509 certificates which servers send back when connecting over HTTPS.
