This section covers topics used to test an application as well as how to distribute it. Topics here include things such as tools used for debugging, deployment to testers and how to publish an application to the App Store.

App Distribution

This article shows how to configure, build, and publish a Xamarin.iOS application for distribution through various different means, including:

IPA Deployment

Ad-Hoc and Enterprise deployments allow developers to create packages that can be distributed for testing or to internal company users. This document explains how to create an IPA that can be synced to an iOS device using iTunes.


TestFlight is now owned by Apple, and is the primary way to beta test your Xamarin.iOS apps. This article will guide you through all steps of the TestFlight Process – from uploading your app, to working with iTunes Connect.

Debugging in Xamarin.iOS

Both the Visual Studio and Visual Studio for Mac IDEs include support for debugging Xamarin.iOS applications both in the iOS simulator and on iOS devices. This article shows how to use the debugger as well as how to configure various options it supports.


This document describes how to create unit tests for your Xamarin.iOS projects. Unit testing with Xamarin.iOS is done using the Touch.Unit framework that includes both an iOS test runner as well as a modified version of the NUnitLite framework that provides a familiar set of APIs for writing unit tests.

Using Instruments to Detect Native Leaks using MarkHeap

This article describe how to use Instruments on any iOS device and any Xamarin.iOS application. It also looks at how to profile applications in the simulator.

Walkthrough - Using Apple's Instrument Tool

This article walks through how to use Apple’s Instruments tool to diagnose memory issues in an iOS application built with Xamarin. It demonstrates how to launch Instruments, take heap snapshots and analyze memory growth. It also shows how to use Instruments to display and pinpoint the exact lines of code that cause the memory issue.

Xamarin.iOS Performance

There are many techniques for increasing the performance of applications built with Xamarin.iOS. Collectively these techniques can greatly reduce the amount of work being performed by a CPU, and the amount of memory consumed by an application.

Xamarin Workbook

If it's not already installed, install the Xamarin Workbooks app first. The workbook file should download automatically, but if it doesn't, just click to start the workbook download manually.
