Did you know Flutter has built-in support for l10n, also known as localization? I’ve been searching for an easy way to localize my app, but most of the blog posts I’ve found rephrased the official documentation on internationalization . I live in Belgium where we have 3 official locales: Flemish (nl_BE), Belgian French (fr_BE) and German (de_BE).
I don’t always have a ton of iOS devices lying around when I submit iOS apps to iTunes App Store Connect. So I take my screenshots on the simulators. At the time of writing Apple requires screenshots made with an iPhone 8 Plus and an iPad Pro. You can optionally add screenshots from an iPhone XS Max.
This post has been translated to Russian by Denis Gordin . You can read the Russian version on the Russian website TechMedia . Thanks, Denis! Xamarin is amazing in how it allows .NET developers to write apps for Android, iOS, MacOS… in C#. But that amazing capability comes with a prize and even the most simple apps can suffer from high memory usage.
The Xamarin profiler is a must-have tool for every Xamarin developer. The profiler comes with a Xamarin business or enterprise license and is available as a standalone installer at xamarin.com/profiler . To get started, make sure a debug version of your app is installed on a device or a simulator (works both for Android and iOS).
What you need Experience with Xamarin.iOS Xamarin Studio for Mac An empty binding project (just create a new project in Xamarin Studio) A very short intro to Objective-C for C# developers Oh god, Obj-C, the most incomprehensible programming language in the app dev world. You simply can’t create an iOS binding project without some very basic knowledge of Obj-C.
There isn’t much documentation available for MVVM Light when it comes to Xamarin.Android and Xamarin.iOS. There are several overloads for the SetBinding method and using the wrong overload causes TargetInvocationException or TargetException like this one . It’s also possible that your bindings don’t update anymore after you set one binding using an incorrect syntax.
You gotta have MVVM A developer and his tools are inseparable. We all like SOLID and every (.NET) developer has his or her favourite dependency injection tool. There is a lot to choose from. I like Autofac because of the way it handles modules, the lifetime of a type and how it registers types.
