Oops – How to fix when you’ve upgraded Visual Studio for Mac / Xamarin iOS and now being forced to upgrade Xcode and to Catalina ????
What went wrong?
So, here’s the scenario, fire up Visual Studio for the Mac, not enough caffeine in the system, an ‘updates’ box pop up, a Xamarin iOS update amongst many, you click ok, then instant regret ????. Why you may ask, an update is good? No? Well not here. Like many developers I have a reluctance to go to Mac OS Catalina (a lot of changes, and too many issues) and am quite happy in the stable, stable land of Mojave. So what have I done?
In essence I’ve upgraded the version of Xamarin iOS from somewhere in the 12.x range to 13.16. I knew the second I’d upgraded it had gone wrong, but opening a Xamarin iOS / Forms project instantly told me. My selected version of Xamarin iOS required an Xcode upgrade to 11.x. Off to the App Store I go, just to confirm, and of course;
Mojave of course is 10.14, Catalina 10.15, so I have to upgrade right, and lose a day of productivity (or more) with it? Wrong.
The fix
So, the solution, first off come out of Visual Studio for Mac, and then drop to Terminal app. Execute these commands line by line (entering your admin password when required);
rm -rf ~/Library/MonoTouch sudo rm -rf /Library/Frameworks/Xamarin.iOS.framework sudo rm -rf /Developer/MonoTouch sudo pkgutil --forget com.xamarin.monotouch.pkg sudo pkgutil --forget com.xamarin.xamarin-ios-build-host.pkg sudo pkgutil --forget com.xamarin.xamarin.ios.pkg
In the meantime I had downloaded the latest 12.16 release of Xamarin iOS. For me this is https://dl.xamarin.com/Mo… however your requirements may vary. Should be as simple as tweaking the download url to suit, you can find 12.x version numbers over here on the Xamarin iOS 12 release notes page.
Once downloaded simply double click and install the package. Then fire up Visual Studio for Mac and fingers crossed, all worked fine for me.

What Is a PHP File?
What Is a PHP File? – Original article at Tutsplus
PHP is a server-side scripting language which is mostly used to build web-based applications. These may range from a very simple blog website to a full-fledged eCommerce website for selling products online. In fact, PHP is one of the most popular server-side scripting languages, with a very healthy market share.
For those that like to geek out, or just understand what’s going on under the scenes, the above link is a really good breakdown on how PHP (the server aside scripting language I use for a lot of my development projects) work.

Arcus Platform version 3.0 updates
Busy start to 2020 for the Askaris Arcus platform, big version 3.0 release translating both the portal and offline tablet interfaces into the end users native language, which will be huge for our client’s Brazilian, Norwegian and other global Operations.
Up next will be a multi-year improvement to the Dropped Object inspection framework, and further translation improvements – including a self learning multi language translation process – this will allow reports to be carried out in a a native language and then proof read and translated into multiple additional languages – another huge time saver.
The Arcus platform is used predominantly in the OIl and Gas sector to facilitate audited regulatory inspections, but as a full Asset Management suite it has uses in many other sectors.

Chrome OS has stalled out – is there a tablet shaped future for Android?
But Android apps, so far as I can tell, are basically the plan for Chrome. Certainly, Linux environment support is great for enthusiasts and developers, but there are very few commonly-used commercial applications available on Linux, with no sign that will change in the near future.
A comment not so much about Chrome OS, but it’s lack of good tablet optimised applications mirrors that of Android as a whole. The Arcus project I lead for Askaris runs primarily on Android powered tablets, but outside of the Atex rated specialised devices sourcing consistent hardware is a struggle, less and less good Android tablets available, and Chrome OS has probably hindered that, not helped it.
A chicken and an egg, no devices, so no users, so no demand, so no apps. Apple at least has the cash and incentive to have jumped into that cycle and invested / motivated. Outside of Samsung and Google (who keep making poor decisions!) who can do that for Android / Chrome OS?
