Apple has simplified PIP implementation in iOS 14

Picture In Picture (PIP) was introduced years ago in iOS 9, but it was only available for iPads. It was brought to iPhones recently in iOS 14, so I wanted to implement it in my app. The iOS 9 documents showed that several steps were involved to implement this, and I was having a hard time integrating that with Xamarin Forms. However, while I was experimenting I realized, Apple made changes to simplify PIP implementation greatly, so those steps are not needed anymore. …

App Store showing app compatibility with Apple’s M1 Chip Mac


A quick solution that doesn’t require the new Silicon Mac

Apple announced that the new Mac computers with the ARM 64 processor will be able to install compatible iOS & iPad apps. Just like you, I was super curious to know if my apps would be “compatible” too. I tried to search multiple articles and blogs to understand what the requirements are, especially for apps created with cross-platform frameworks, but I couldn’t find anything. Aside from compatibility though, there is a way to “opt-out” through the Apple Developer portal, so your app is not available for Macs. While clicking around, I figured this out and thought I would share.

Here’s how to find out

When we were learning Xamarin a few years ago, “Xamarin University” was a great resource to learn and understand the fast-growing Xamarin framework (now MAUI). It was the official way of gaining Xamarin Certification and ramping up on a recognized skill. There’s a void that Xamarin University filled, it was a structured path to learn and become a confident Xamarin professional, so we partnered with Luis Pujols to dive into what beginners can do.

A Xamarin University existed?

For 6 years, anyone who was interested in getting into C#-based Native Mobile Development, could simply follow through the well-taught courses on “” for as little…


Stop manually deleting the bin & obj folders from today

If you have done a weeks’ worth of Xamarin mobile development, you know the need to frequently delete the bin & obj folders in each sub-directory of your solution. This tedious process essentially clears the cache and deletes any improperly built code, so that you can recompile your code, and this magically solves half the problems you face.

All these 11722 unneeded auto-generated files deleted with one command

How does this work?

To achieve this we are going to take advantage of how projects with git version controlling setup correctly, will only “track” the necessary files that are not “auto-generated”. So in order to make this work, you need a file named .gitignore file…


Adding device frames to screenshots is now a single command!

Have you have ever needed to share your app screenshots with other team members, but skipped adding the frame just to save time? Taking a screenshot is as simple as a click, but designing & dealing with image editing tools is definitely not a developer’s forte. Well, adding a device frame is now a simple keyboard tap!

While lurking in the iOSProgramming subreddit, I saw an answer to a question taking me to Fastlane’s page teaching how to take screenshots using automated UI Tests. And there, I stumbled upon the frameit command.

November 2 is coming close, be proactive to avoid a meltdown

Using cross platform frameworks like Xamarin has a lot of pros, in terms of the shorter learning curve and time of development. But changes needed due to unforeseen change in the native iOS & Android SDK’s is one of the disadvantages, as you will see in this article.

Spend $1 on 2 NFC tags to test it out yourself

Many of you must have heard/read about NFC, and possibly used it to pay using Google Wallet or Apple pay. As developers, we are gifted with the knowledge and ability to actually interact and create products that use such technologies. It may seem intimidating since you may not be familiar with electronics at first, but the good thing is that these cost about a dollar a piece, so it’s alright even if you blow one up. …
