In recent weeks we’ve talked a lot about Monkeypod, our cloud-based API design and virtualization tool that produces beautiful, living API documentation and allows teams of developers to collaborate concurrently to design APIs. Today we’re diving a little deeper and discussing Monkeypuzzle.

What does Monkeypuzzle do? 

Monkeypuzzle uses the Monkeypod API design to create a virtual API that serves as a nice starting point for developing client side solutions, and API integrations. Out of the box, it creates Json responses based on the Monkeypod models that are populated with random data.

But random data is not always ideal.

Apple announced yesterday:

Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code.

This means any projects in process need to switch to iOS 8 and 64-bit if they are going to launch after Feb 1. More importantly, all updates to old apps after that date will not be accepted unless the apps are updated.

To Do: Check immediately what iOS and what bit support (64 or 32) all you current public apps include, and begin making update plans for any legacy applications to ensure you don’t end up with an update you cannot submit.

As always, please do not hesitate to contact us if we can be of assistance.

No big surprises from Apple, but a few things developers need to keep their eyes on:

Apple Pay: iOS 8.1 will get pushed to users on Monday, and the most important piece is that Apple Pay will now be live, supported in 220,000+ stores out of the gate. For app developers, the biggest innovation is that you can integrate Apple Pay into your apps to permit purchasing (of non-digital goods). Retailers, of course, have an equally big opportunity in their bricks and mortar stores. We at WillowTree tend to be cautious about consumer adoption of new technologies, but we think Apple has the timing and implementation right on this, and Apple Pay will be a very big deal.

Handoff: In iOS 8.1, apps that implement Handoff can now offer a seamless experience among multiple devices. So if you are looking for a store, product, or coupon on your iPhone, you can pick up an iPad, open the app, and be on the exact same screen. There are obvious media delivery applications here for movies, articles, gamecasts, etc., but we think commerce and shopping applications can also benefit. Handoff will essentially be useful anytime a user has an extended interaction that might be interrupted. Recipe apps are a great example as users spend time searching and sorting recipes in the morning, shopping after work, and cooking that night. For these users, being able to hop back and forth between the iPhone and the iPad without loss of state presents significant benefits.

Apple Watch: The biggest news for developers is that in November, we get access to the Watch SDK, WatchKit. While we won’t actually see watches until early 2015, we already have a few client projects in the hopper, and would love to add more. If you have Watch concepts you’d like to explore, please let us know and we’d love to work with you on some prototyping.

Today we’re following up on our earlier post about mixins, and discussing another mixin we’ve found useful. Before we dive in, here is a simple demo with all the relevant code under the javascript tab.

In many apps you will need to pop up a modal and block all user interaction until the user responds to the prompt. This is very similar to the native  confirm   command.

Here we present the user with a Yes / No dialog box and proceed depending on…

On larger software projects, one of the biggest challenges to a successful and timely delivery is aligning the efforts of multiple teams. Understanding the web of interdependencies and planning the development schedule of related subsystems is a full-time job on many projects. Even with careful milestone planning and employment of agile techniques complex projects inevitably run into situations where the efforts of one team are blocked by a late deliverable from another team.

As enlightened software developers, we understand that no amount of planning ahead of time can force a creative endeavor like software engineering to fit neatly on a calendar. But we also recognize that no amount of flexibility and agile pivoting can completely mitigate the fact that sometimes teams will be blocked waiting on other deliverables. So how can we minimize the risk to the overall product timeline?

In mobile development, especially large scale Enterprise integration projects, we most frequently run into situations where a backend API is not complete enough to proceed with client application development. In those situations, what we really wanted was a way to allow development of each to proceed unimpeded by the other. Just as our software architecture aimed to be a set of loosely coupled components, our development process needed to minimize interdependencies, allowing teams to work on different parts in parallel while communicating through common interfaces.

Decoupling API Development

In order to decouple API and client development, effectively allowing concurrent development on each, we found we needed two key things:

  • A common description format for an API to serve as the primary reference for any team interacting with the API. This description should be the canonical point of validation for the API itself as well as any systems that interact with it. It should provide human readable documentation to aid development and be a machine-readable specification that tooling can build on.
  • A way to simulate…

One of the major impediments to the rapid adoption of mobile by large enterprises and institutions has been that Application Programming Interfaces (APIs) must first be created to connect legacy systems to mobile or other devices. Without mobile-optimized APIs, the apps consumers and employees want simply cannot get access to the underlying data to be useful.

To enable development teams to more quickly create and test APIs with less wasted time and resources, we are proud to announce that WillowTree has beta launched a cloud-based rapid API design and virtualization tool called Monkeypod™.

Many mobile projects continue to be delayed by either waiting on APIs to be completed or building mobile applications and APIs concurrently. The latter approach often results in a mis-match, creating rework and further delays — much like a tunnel being built from both ends and failing to meet in the middle. As Forrester Inc.’s February 2014 report A Benchmark to Drive Mobile Test Quality states, “Service virtualization is the key to enabling back-end and front-end development teams to deliver on an independent cadence.”

“Until now, developers have faced two bad choices for beginning mobile projects where APIs either don’t exist or are in flux: wait until the APIs are ready, which often delays a project by months, or build the apps and APIs concurrently based on existing documentation. This invariably requires weeks of rework because the final APIs have differences from the client-side implementation,” commented Michael Prichard, Founder & Chief Technology Officer of WillowTree. “Monkeypod eliminates this problem by enabling developers and architects to design, immediately expose, and test a working API or web service and automatically create related documentation. This enables various back-end and client-side teams to work concurrently, with almost no risk of rework, to more quickly create robust mobile apps.”

Based on standards including HTTP and JSON,…

It’s been a few months now since Apple unveiled their first foray into the multi-trillion dollar health sector with HealthKit, but it’s still difficult to say what they have in mind in the long run. For those who weren’t tracking the WWDC announcements this year, HealthKit is the toolset provided to developers to capture health information (breath and heart rates, nutrition, etc.) and store it in a shared user profile across the device. This profile is visible in the Health app included in iOS 8, providing a central dashboard for all of the information that’s being piped in from any number of applications.

For developers, this makes storing data much more appealing since Apple is taking the security of this data very seriously. Historically, the penalties for failing to secure health data properly have been draconian to the point that companies have avoided trying to store the data entirely for fear of being bankrupted by a minor oversight in their code. There is some risk for developers that making the information that they track accessible to all other apps could be sacrificing a competitive advantage, but the trade-off is likely worthwhile for anybody who doesn’t want to dedicate a huge chunk of resources to software security. In the case of some products, the availability of a shared profile also streamlines the onboarding experience, obviating the need for manual input of any of the metrics already being tracked.

There is a strong incentive for Apple to make this platform attractive to developers as HealthKit users will have a bank of data tied directly to their iOS device, and that data will not be transferrable to a competing product if HealthKit gains significant traction. Considering how much Apple has invested into the technology, though, we likely haven’t seen all they have up their sleeve. While they’ve been tightlipped about their long-term strategy in the health sector, the Apple Watch announcement made it clear that…

Beyond the exciting news surrounding the Apple Watch and iPhone 6, Apple’s announcement of their new Apple Pay platform is arguably one of most revolutionary changes out of this year’s iOS 8 event. Apple’s push into the mobile payment space will not only be a huge benefit for iPhone users but will also help bring NFC and mobile payments into the mainstream.

Here are the top 3 things you need to know about this new and and very exciting platform from Apple:

1. NFC Payments

Apple Pay opens up the world of NFC contact-less payments to iPhone 6 and iPhone 6 Plus users. It’s going to be very easy for people to get started with Apple Pay. Here’s how it will work:

  • Users can simply opt to use the primary credit card Apple already has on file for them in iTunes. If a user wants to add a different card, all they have to do is take a photo of that card and add it to the Passbook app.
  • Once a credit card is added to the device, the information used to make a payment is stored in the iPhone 6’s secure element. This ensures the integrity of the card information as Apple does not store your card or payment history to keep your data private.
  • Once the cards are set up, the user can simply scan their finger using the TouchID sensor and tap the phone or Apple Watch to the payment terminal to pay for items in-store.

Apple is also supporting NFC payments for users with iPhone 5 and 5s that purchase the new Apple watch, allowing users with older devices to join the NFC payment world. If your device is ever lost or stolen, Apple has also provided a method to remotely disable purchasing power of a device to keep your payment information safe.

2. In-app Payments

As part of the Apple Pay release, Apple is providing developers the ability to roll out support in their…

Tuesday’s iOS 8 event included some of the most substantial announcements in years from Apple. The changes to phone size, the payment platform and Apple’s smartwatch are all mobile game changers. This was the most significant launch event since the iPad — and if you remember, the iPad was met with similar criticism as the watch is being subjected to today. Four years later, it is clear the iPad changed mobile computing (and in fact computing overall) — we believe that four years from now we’ll all see the Apple watch in the same light. Let’s look at how Tuesday’s announcements impact mobile strategy and apps currently in the marketplace or under development: 1. The Big Screen x 2 (iPhone 6 & iPhone 6 Plus)  To the surprise of almost no one, yesterday Apple revealed two brand new iPhones, the iPhone 6 and the iPhone 6 Plus. As pre-event rumors suggested, the new iPhone models are sized at 4.7-inches and 5.5-inches respectively and greatly increase the amount of real estate that developers can utilize in apps. Interestingly, the iPhone 6 Plus allows for different and varied layouts compared to the iPhone 6 and iPhone 5. The iPhone 6 Plus allows more content to be visible and supports iPad-style layouts in landscape mode. These layouts are made available via “size classes” that allow developers to provide unique layouts for variations in screen size and orientation.  The iPhone 6 (like previous iPhones), will support the “compact” size in landscape mode, whereas the iPhone 6 Plus supports the “regular” size class which allows it to display more content. In order to support multiple screen sizes and size classes, Apple has made “auto layout” available in previous OS versions; however until now, the benefits of using “auto layout” have not been fully realized. To Do:

  • Immediately run all existing apps on the new screen sizes in iOS 8 using the simulator to test how your apps will appear and behave, given the new combination of OS and devices. Many older apps will not…

Apple fans across the world were treated to a number of exciting announcements at today’s iOS 8 event. Our team is excited by all of Apple’s news too and we’ll be covering all things iOS 8 on the blog for the remainder of the week. Without further ado, here are our first iOS 8 impressions:

iPhone 6 

Apple is going big this year with two new iPhone sizes, the iPhone 6 and the iPhone 6 Plus.  These new sizes greatly increase the amount of real estate that developers can utilize in their apps.  Interestingly, the iPhone 6 Plus will allow for different and varied layouts as compared to the iPhone 6 and iPhone 5.  For our clients, this change means more opportunity to create compelling interfaces that match the form and factor of devices they use. Not only will apps be able to take advantage of the larger iPhone 6 Plus screen sizes, but they will also scale down elegantly to fit  iPhone 6 and iPhone 5 screens.

As developers, these new screen sizes mean we need to take advantage the new iOS 8 APIs (e.g. size classes and auto-layout) in order to continue building our clients elegant apps. Fortunately, Apple also revealed that existing apps can be scaled automatically to fill the screens of the new iPhones. That said, taking full advantage of all the new functionality of these devices will require deliberate thought around how to best leverage the newly available screen space.

Apple Pay

Apple Pay is arguably one of the biggest announcements of iOS 8 and marks the arrival of seamless mobile payments for iPhone 6 and iPhone 6 Plus users. Those who purchase one of the new devices will now be able to easily scan their existing cards into the iOS and make mobile payments anywhere NFC transactions are accepted. Additionally, users with stored cards can now make seamless payments online, and possibly within apps too. Apple’s jump into the payment space means big things for…

A never-ending and often emotional debate in mobile development circles remains whether to use a deep cross-platform tool such as Xamarin, or develop apps natively? It’s almost impossible to find impartial analysis as nearly every reviewer comes in with an underlying bias. At WillowTree, however, we use both approaches, and in the end it all depends on the project and your organization. Here are some things to think about when we tackle this all-important platform problem for a client:
