1 CIS195 - Intro to ios App Development Lecture 12 Josh Pearlstein Spring 2016

2 Announcements Great job with Homework 5 Grading is slow Weekly Project Meetings Presentations on April 29th 12-2PM. - If you can t make this me ASAP

3 Review

4 Dependencies? You re not the only ios Devs out there - Some people are pretty good at this stuff Some of these people make their code available to others - And you can use this code! How do you use this code? - You already saw one option with Homework 5 - There are others

5 Adding External Code Directly Copy the files into your project - Only possible if you re using a small amount of external code (e.g a couple of classes) What about larger amounts of external code? - Not all of the functionality might be exposed - Sometimes, this code has dependencies And these dependencies might have dependencies Build time goes up fast - Is there an easier way?

g a couple of classes) What about larger amounts of external code?

6 CocoaPods One of the most widely used and supported dependency managers for Xcode - Alternatives are: Xcode Maven VendorKit Others? Provides access to dependency source code Dependencies are placed in a separate project - Keeps your project clean - This project is linked to yours via a *workspace*

Provides access to dependency source code Dependencies are placed in a

7 CocoaPods - Great guides and references - I ll cover the basics in the next few slides

8 Getting Started With CocoaPods Working with CocoaPods mainly involves using the command line - You can access this via the Terminal app Install CocoaPods via Ruby - CocoaPods is just a Ruby gem Don t worry if you don t know what this is - Use the following terminal command to install: sudo gem install cocoapods There s a sudo-less way to do this too See the Getting Started guide on the CocoaPods website

worry if you don t know what this is - Use the following terminal command to install: sudo gem

9 Adding CocoaPods to your project You need to add a Podfile to your project directory - You can do this manually (hard mode) - Or you can have CocoaPods make one and add it for you Just run this command in your project directory pod init - Sample Podfile:

Or you can have CocoaPods make one and add it for you Just run

10 Installing Dependencies The Podfile only specifies to CocoaPods the dependencies you want - This doesn t necessarily mean they re installed To install dependencies, run this command: - pod install - This should be run where your Podfile is located Now your dependencies are installed! Now what?

To install dependencies, run this command: - pod install - This should be

11 Workspace? When you install your dependencies, they go into a separate project - Your project stays clean and neat How do I access these dependencies then? - CocoaPods links your project and it s dependencies via a workspace - A workspace is just a way of grouping together multiple projects and builds - All you have to do is open he workspace file instead of your project file - You can still work with your project like normal, there will just be more stuff (files) in the File Inspector

12 Is that all? Almost - Once you have your workspace all set up, you can go back to development as usual - You can add dependencies whenever you want Just run the install command again - When you need to use one of these dependencies in code, just import it! You can create pods as well - I won t cover this, but it s pretty easy to integrate - Take a look at the guide for it on the CocoaPods site

can add dependencies whenever you want Just run the install command again - When you need to use

13 ios Frameworks WatchKit

14 WatchOS A Watch app complements your ios app; it does not replace it. If you measure interactions with your ios app in minutes, you can expect interactions with your Watch app to be measured in seconds. Apple Watch Human Interface Guidelines

15 WatchOS

16 Watch Interactions There are a few different ways Apple allows users to interact with the watch - Glances - Complications - Notifications - WatchKit Apps

17 WatchKit Apps Created using storyboards just like ios Apps UIKit objects replaced with watch versions - WKInteraceController - WKInterfaceLabel - WKInterfaceImage Instead of viewdidload and viewdidunload - didactivate diddeactivate

WKInteraceController - WKInterfaceLabel -

18 Communication Between Devices Uses WCSessions Passes a dictionary or raw data from watch to device Phone can respond with dictionary or raw data Bluetooth is slow, don t transfer big files Low memory on watches

can respond with dictionary or raw data Bluetooth is

20 App Store Submission So you ve made an App

21 So you ve made an App How do you get it onto the app store? - Submit it to Apple for review - Not so simple

22 Provisioning Profiles Overly Simplified Overview: - Entitlements file + Bundle: What does this app want to do? Developer signature AppID Signature - Provisioning Profile: What is this app allowed to do? Apple signature AppID Signature Types of Provisioning Profiles - Developer: For installing on developer registered devices 3 month expiration - Distribution (ad-hoc) For installing on beta-testers devices 1 year expiration - Distribution (App Store) Shipping

23 Uploading to Apple Make sure your code is complete and all permissions granted Test on all types of devices and supported operating systems Switch your target device to Generic ios Device Archive your project Go to Organizer - Select your project - Hit Verify - Hit Submit - Fill out the paperwork - Export compliance? Crypto? - Wait days

24 Stages of App Review Review Approval Rejection

25 Rejections Happen Usually about metadata or crashes Fix the changes or submit an appeal Get big enough no longer a rejection but a conference call Most common rejections: - Crashes and Bugs - Substandard User Interface - Broken Links - Advertisements - Placeholder Content - No beta apps! Use Testflight - Incomplete Information - Web clippings, content aggregators, or a collections of links - Repeated Submission of Similar Apps - Inaccurate Descriptions - Misleading Users - Not enough lasting value

26 Expedited Review Requests If you face extenuating circumstances, you can request the review of your app to be expedited. These circumstances include fixing a critical bug in your app on the App Store or releasing your app to coincide with an event you are directly associated with. Urgent Bug Fix - If you've submitted an update to fix a critical bug in your app on the App Store and you are requesting an expedited review, be sure to include the steps to reproduce the bug on the current version of your app. Time-Sensitive Event - For apps associated with an event, we recommend you plan and schedule the release of your app in itunes Connect. However, if your app is still in review and the launch of your event is quickly approaching, you can request to have your app review expedited. When submitting your request, it's important to include the event, date of the event, and your app's association with the event.

27 Useful Frameworks to Include Making a new app? - Crashes will annoy users Useful frameworks for new apps - Instabug Shake phone to submit a bug report - Mixpanel Analytics and notifications very useful - Appirater After x number of launches over y weeks ask the user to review the app - Rollout Really cool framework Code swizzling in production

28 Logistics Quiz this week - Due next Wednesday at 11:59PM TAs and I will hold some office hours in the coming weeks

29 Demos Informal 8-10 minute presentations You can use your phone + quicktime or demo on the simulator Code submission due Tuesday 5/3 at midnight Final project final grade - 10% Milestone meetings - 30% Demo - 60% App + code
