  • Parse – for user management and uploading video files
  • Fastlane –  for deployment of test builds and screenshot generation for App Store listing.

Project Management

  • Slack – integrated with Github and Trello. Used for project work and community.

Other Software

  • Balsamic Mockups 3 – upgraded to the latest version (free upgrade from purchase years ago – thanks :-))

30 Word Sales Pitch and Free App Store Template Download

Can you sell your app in 30 words? No? Bad news, because that’s all you get in the App Store.

These screenshots show the small amount of space available for your app description.

These screenshots also highlight the importance of the app name. This is the only key information shown on the main App Store listing. It is also given a lot of real estate on the app detail screen.

The most important aspect of these screens are the screenshots. These take up the majority of the screen. The first screenshot can be an app preview video. With limited opportunities to sell to a user, these 15-30 second app preview videos are a great option.

Another common option is to add header/footer text or captions to your screenshots. This allows you draw attention to the key benefits or features of your app.

In summary, the most important parts of your app store listing are:

  1. Screenshots
  2. App Icon
  3. App Title
  4. App Description
  5. What’s New

I’ve created App Store templates for experimenting with icons, descriptions and screenshots. This allows you to consider how a user will interact with your app at the point of sale.

This should be a significant consideration as part of your design process.

Using this information

You can use these screens as a starting point for creating your app. Build your sales messages into your plan from the start.

  • Can you easily describe your app?
  • Can you show the benefits of the app in a screenshot?
  • Will your users understand it?
  • Will it sell?

Download these free resources as PDF’s and start planning your app.

Xcode Runtime Attributes

The last 1% of pixels in an app, take 10% of the time.

Quickly changing a button to have rounded corners and a coloured border is still not completely possible in Interface Builder. The use of Runtime Attributes does make it easier though.

With Expanding User-Defined Runtime Attributes in Xcode with Objective-C, a few more uses have come to light.

The list of possible values is wider than I realised including Boolean, NSNumber, NSString, CGPoint, CGSize, CGRect, NSRange, and UIColor. And it’s the inclusion of UIColor that makes it really useful. As long as you’re happy using the color picker.

But not even UIColor can help with a button border color. For that you’ll need CGColor. Mike Woelmer has provided a CALayer+RuntimeAttribute category to help.

While this approach keeps the view controller code cleaner, there do seem be some inefficiencies in applying the same attributes to multiple controls.

As mentioned by Sam Dods in his Interface Builder tutorial, this approach may lead to future code maintenance issues if other developers don’t realise that runtime attributes can be set in this way. More reason to share this knowledge further.

This post has been written in the spirit of “Write about something you’ve learnt, when you’ve just learnt it.” – Ash Furrow, echoed by NatashaTheRobot.

Apple Watch Prototyping

ThinkApps has launched a prototyping tool that allows you create interactive mockups of your Apple Watch idea. This provides a great way to get hands on with the device.

MarvelApp has released a new version of their app which included a Watch app. The new feature allows you to run your MarvelApp Watch prototype on your device.

Develop Quickly with JSON

A large amount of app development involves integrating with third party systems, typically via an API. More typically via JSON. Paw is a great tool for working with API’s. It’s super simple to create your requests and organise them into groups. I typically group by API call, staging or production, for various testing accounts. It also simply handles authentication.

Paw has code generators which export the ObjC code required for your API call. My workflow currently involves using Cocoa JSON Editor for this purpose. It’s more heavyweight approach will create ObjC classes for object models of the API response.

Using these tools allows you can quickly evaluate an API. They both offer a visual approach to modelling the data and structuring your classes.

Continuously Learning Xcode

For an indie developer it’s important to hear how other developers are working. Ben Scheirman of NSScreencast is posting an interesting series on his development of an app. Just watching how others work is really useful to spot shortcuts and efficiencies in development. A subscription is required for full access, but the first three videos (Part 1Part 2Part 3) in this series are available for free.

A couple of tips from these first videos. SimPholders2 is a utility which saves minutes off the tedious process of navigating the Finder to the folder structure for your app in the simulator. gitignore.io will generate your gitignore file for your project.

Version History

This is version 1.2 of the app. Version 1 released 15 Jan 2015, with Version 1.1 released 10 Mar 2015. Some early review indicate issues with app reliability. The majority of recent review are positive.

Developer Website

A truly beautiful website for MacID. More great copy for the app. All very Apple in design. Links through to his personal blog which has a couple of articles which appear to be his first experiments with the mechanisms that make up MacID. He also has an extensive run down of iOS8 features where he mentions the TouchID API.

App Rankings

MacID for iOS App Rankings

The app has multiple peaks and troughs only recently levelling out at the top of the charts, primarily caused by the price change from £3.99 to £0.79.

MacID for iOS App Rankings

Summary

Much can be learned from this app. A simple mechanic for the app. A simple well designed icon. The screenshots are selling this app. The price has been the trigger for the number one position.

It looks like that the app at the top of the App Store charts in mid May 2015 was probably first conceived at WWDC in June 2014. Just another App Store overnight app success.

NSConference Videos

NSConference has established itself as one of the best iOS Development conferences. That all came to a close this year. I was lucky enough to attend and am looking forward to watching the newly released NSConf7 videos. I was amazed to see that Scotty has uploaded what looks like every video from every conference which is just an amazing resource.

I can recommend:
