Develop a simple iOS mobile app (toDoList) using Swift – Part 1

Swift is an innovative new programming language for Cocoa and Cocoa Touch. Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

Here are some of features:

  1. Modern
  2. Designed for Safety
  3. Fast and Powerful
  4. Interactive Playgrounds
  5. Ready Today
  6. Read-Eval-Print-Loop (REPL)

Getting Started.

Before we start this tutorial, make sure you already setup your machine (mac) with these tools:

  1. Xcode 6.3.2 GM seed – https://developer.apple.com/xcode/downloads/ (More stable than Xcode 6.3.1).

Open Xcode and create a new Single View Application. For product name, use RevivalxSwiftToDoList and then fill out the Organization Name and Organization Identifier with your customary values. Enter Swift as Language and make sure only iPhone is selected in Devices.

Install CocoaPods using terminal. What is CocoaPods?

CocoaPods manages library dependencies for your Xcode projects.

The dependencies for your projects are specified in a single text file called a Podfile. CocoaPods will resolve dependencies between libraries, fetch the resulting source code, then link it together in an Xcode workspace to build your project.

Ultimately the goal is to improve discoverability of, and engagement in, third party open-source libraries by creating a more centralised ecosystem.

Reference: https://guides.cocoapods.org/using/getting-started.html

Open your terminal and type this command.

sudo gem install cocoapods
sudo gem install cocoapods

sudo gem install cocoapods

Go to your directory and initialize your pod using this command.

cd /Users/MNurdin/Documents/iOS/RevivalxSwiftToDoList
pod init
pod init

pod init

Open your finder and edit pod file (Podfile) with these one.

# Uncomment this line to define a global platform for your project
#platform :ios, '8.0'
use_frameworks!

pod 'HanekeSwift'
pod 'Parse'
pod 'ParseFacebookUtils'
pod 'ParseUI'

target 'RevivalxSwiftToDoList' do

end

target 'RevivalxSwiftToDoListTests' do

end

The reasons why we need these libraries because

Go back to your terminal and run pod install to install all the dependencies. It takes a few of minutes to download.

pod install
Pod install.

Pod install.

After finish downloading, open RevivalxSwiftToDoList.xcworkspace file, not RevivalxSwiftToDoList.xcodeproj because we want to use the pod.

Storyboards and interface builder

From the Object Library, drag a Bar Button Item to the right of the navigation bar on the Table View Controller. Select the Bar Button Item (which has a default value of “Item”) and in the Attributes Inspector, in the Identifier option, choose Add. This will change the button to the add symbol (+).
