1. Swift for lazy iOS Developers @iAshishKapoor @AshishKapoor www.kapoor.tech
2. You have 20 days and been assigned a small project/app to submit a good enough PoC or the whole application itself. What are you going to do?
3. And you’re like...
4. What if I tell you, It’s possible!
5. “Beginners?” look up for this term called: A curated list of awesome iOS ecosystem, including Objective-C and Swift Projects Getting Started Libraries And Frameworks Animation Charts
6. How to include the frameworks or libraries in your project? There are two ways you can: 1. CocoaPods 2. Carthage
8. Steps to setup cocoapods on your mac Step 1: open a command line in the project directory and use gem install cocoapods to install cocoapods Step 2: So go back into the project directory and do a gem install cocoapods. Step 3: Now type pod install to get the pods project fully created. It will take some time initially because CocoaPods uses a single central git repo of all the available dependencies and it has to download that first.
9. Simple Steps: # Installation $ pod install # Updation $ pod update # Implementation $ pod init XCODEPROJ Template of a Podfile: # Define a global platform for your project # platform :ios, '10.0' target 'XCODEPROJ' do # If using Swift and don't want to use dynamic frameworks use_frameworks! # Pods for XCODEPROJ pod 'Alamofire', '~> 4.0' end
10. Demo: Cocoapods
11. - A simple, decentralized dependency manager for Cocoa And there comes another approach altogether… Carthage
12. Step 1: Install Carthage. You can download a DMG installer from the Carthage GitHub page. Step 2: Good, open a command line in the project directory and use carthage bootstrap to download and build the dependencies or type $ brew install carthage Step 3: That’s it. Step 4: The only time you have to worry about it again is if you want to update the dependencies. Then you just update the Cartfile with the new dependency or version and run carthage update. The format is just a simple list of dependencies so it's easy to do. Steps to get success with carthage:
13. Demo: Carthage
14. 1. Alamofire - URLSession handling 2. Kingfisher - Images handling 3. Spring - Easy animations 4. Realm - The alternative to CoreData and SQLite 5. SwiftyJSON - Json parsing is neat and type safe … References: “github.com/trending/swift” Top 5 Open Source projects for iOS:
15. Common mistakes using Swift Libraries Pods dependencies lock Swift version differences Cocoapods version differences
16. Example: Implementation of Tinder like cards on iOS Yalantis/Koloda Answer
17. Good practises of using Open Source Libraries Licenses & Standards The following OSI-approved licenses are popular, widely used, or have strong communities: § Apache License 2.0 § BSD 3-Clause "New" or "Revised" license § BSD 2-Clause "Simplified" or "FreeBSD" license § GNU General Public License (GPL) § GNU Library or "Lesser" General Public License (LGPL) § MIT license § Common Development and Distribution License Source: https://opensource.org/licenses
18. Be a badass contribute to open source libraries
