Building Blocks

Leave a reply

I am currently working on a User Authentication module for a Django project and am anticipating using this in other Django projects. Wondering, not just with the User Authentication module, but other similar common building block modules that I could be working on and using in various projects – how would I plan on doing that.

I am also, for now at least, using Django as my backend for not only the web and mobile applications I am currently working on but also the native iOS apps I have plans to begin soon.

iOS Autolayout

Leave a reply

UI is my weakest link in my Software Development journey. But with iOS Autolayout, I am getting a slight taste of the challenges faced when designing the User Interface. My biggest challenge right now – designing for both iPAD and iPhone. Designing just for iPhone has become complicated enough given the range of devices – iPhone 5s to iPhones XS Max.

Dev Workstation Setup

While there is an emphasis on the “dev” portion of my workstation – mostly because there is more of a need to ensure the various tools and their compatibility is maintained. I do want to clarify that I use the same workstation for my personal stuff too.

cocoapods

Leave a reply

While I try to figure out why all the available PODs seem to be written in Objective-C (and not Swift) I need to make notes for using Objective-C (in addition to using CocoaPods) in my iOS App(s).

Pre-Req:

  • Xcode
  • cocoapods
  1. Create (and save) a Project
  2. on a Command Line Shell cd into the location of the App
  3. Run “pod init”
  4. Edit the “Podfile” that is created
    1. add the specific POD Framework entry
    2. Uncomment “use_frameworks!”
  5. Run / execute “pod install” (from the command line)
  6. Close the “Project” and open the “Workspace” (.xcworkspace file)
  7. If the POD Library is in Objectve-C, will need to follow the next few steps (to create a Bridging Header)
    1. Right Click on the Main Folder for the Project and Create / Add a New Objectve-C File (call it anything you want)
    2. Follow the flow till it asks to “Configure an Objective-C bridging header”. Definitely choose / select this option
    3. There should be a couple of files that gets created / generated. Delete (or not) all the files except for the one that ends with “-Bridging-Header.h”
    4. Edit the “-Bridging-Header.h” file to add the “import” for the POD Library
    5. Now to use the POD Library in any class, just add the “import” in the class file(s)
  8. that should do it

Python, Ruby & Swift

Leave a reply

These are simply programming languages to help us learn “Object Oriented Programming”. While we will be trying to learn each of the languages as best we can, the goal is to learn to Program and user “Object Oriented Programming” as the foundation.

Data Structures

Struct

Class

  • Class Inheritence

Struct vs Class

  1. Class requires initializer to be written and Struct does not require
  2. Struct is of “Value Type”, Class is “Reference Type”

Method

  1. Instance Method

Initializer

Default / Memberwise

Functions

Optionals (need to go over) / Unwrapping Optionals / Optionals Chaining
