Xamarin.Forms - Icons in Navigation Toolbar

A somewhat common scenario for mobile apps is to place an icon in the center of the Navigation Toolbar. While I am not sure if this is really best practice in 2018 there still seems to be a lot of demand to do this. What if I was to tell you that this is actually pretty easy to do and for iOS it is built directly into Xamarin.Forms with no need for a custom renderer?Let's take the default "Master/Detail" template for Xamarin.Forms in Visual Studio. It has a few tabs and an about page that has th…

Streamlined TestFlight Registration with fastlane

I think we all can agree that attempting to do beta testing on iOS is pretty terrible. You can't side load apps easily, provisioning profiles are terrible, and manually adding people to TestFlight is no fun. All I want to do is get my app in users hands! Why do I have to go through so much stress? Well you don't, because fastlane comes in to save the day just like it simplifies provisioning in Visual Studio for Mac. The issue with TestFlight So TestFlight is a bit better now that we can add 10,0…

iOS 11 Missing Marketing Icon

It is update season for iOS and Android applications with new versions of the operating systems being released. Today, I was on my way to push out a new version of the Xamarin Live Player to Test Flight users and hit this nasty error: Missing Marketing Icon. iOS Apps must include a 1024x1024px Marketing Icon in PNG format. Apps that do not include the Marketing Icon cannot be submitted for App Review or Beta App Review. What is that?!?!? I swear I uploaded the icon to iTunes connect. Well...…

Dynamically Changing Xamarin.Forms Tab Icons When Selected

Spicing up your Xamarin.Forms tab can easily be done in a few ways. You can add tint color in Android when the user deselects a tab, which can also be done in iOS in addition to a full swap of a selected image. It was recently pointed out to me that these blogs highlighted a way of adding back a bit of nativeness, but didn't answer a different question of how to actually completely change the icon itself when a tab is selected. This question caught me off guard as I have never really changed th…
