Sep 09, 2017 Yes, you can use one of Apple's several desktop PCs. There is the high end Mac Pro desktop (nicknamed the trash can) but it is super expensive. There are the iMac all-in-one PCs with the computer built into the rear of the screen housing. Your Mac won’t run on Apple hardware, but it will run macOS. A Mac Build Server, which is a specialized kind of Mac that can be used to compile iOS apps. You’ll create those apps on your Mac, and then instruct the Build Server to compile the app for you. A dedicated Mac. Dec 08, 2016 To develop iOS apps using the latest technologies described in these lessons, you need a Mac computer (macOS 10.11.5 or later) running the latest version of Xcode. Xcode includes all the features you need to design, develop, and debug an app. Xcode also contains the iOS SDK, which extends Xcode to include the tools, compilers, and frameworks. Apr 15, 2019 Things have to be specific, Xcode changes frequently, iOS firmware does too; even dedicated iOS developers have issues bridging the projects due to frequent updates. You need to know however that you need an Apple ID, and you may only create up to 10 App IDs every 7 days, You also need iOS App Development Provisioning Profile. I am trying to use Xamarin in VisualStudio for developing iOS application. VS is asking me for Mac Build Host. I have registered as iOS developer and paid for it, expecting that it is enough for development, but it seems that I also have to purchase a physical Mac desktop (which was not in my budget at all, after I invested additional few hundred bucks for an iPad mini, which I actually did.
These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Download macOS
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS MojaveormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.

Enterprise administrators, please download from Apple, not a locally hosted software-update server.
OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Catalina:*
Mojave:*
High Sierra:*
El Capitan: - Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath
argument, similar to the way this argument is used in the command for El Capitan.Use the bootable installer
After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Because developing an iPhone and/or an iPad app requires you to work in an Xcode project, it’s time to create one. The app you’ll be building is called RoadTrip (and will also be the name of the project). The app is like a travel guide on your iOS device. Here’s how you get your RoadTrip project off the ground:
1Launch Xcode.
Simply go the Mac App Store, search for Xcode 5, click the Free button, and then click the Install App button that the Free button transmogrifies into, and you are done. After the download, you’ll find Xcode in your Applications folder. Double-click to launch it.
Here are a couple of hints to make Xcode handier and more efficient right from the start:
Create a shortcut. Control-click the Xcode icon that appears in the Dock and then choose Options___Keep in Dock. You’ll be using Xcode a lot, so it wouldn’t hurt to be able to launch it from the Dock.
Nix the Welcome to Xcode screen if you’d like. When you first launch Xcode, you see the Welcome to Xcode screen with several links. (After you use Xcode to create projects, your Welcome screen lists all your most recent projects in the right column.) If you don’t want to be bothered with the Welcome screen in the future, deselect the Show This Window When Xcode Launches check box.
You can also just click Cancel to close the Welcome screen.
If you ever want to see the Welcome screen again, you can access it through the Window menu or by pressing Shift+⌘+1.
2Click the Create a New Xcode Project link on the left side of the Welcome screen, or choose File→New→Project to create a new project.
Alternatively, you can just press Shift+⌘+N.
No matter how you decide to start a new project, you’re greeted by the Choose a Template for Your New Project sheet (a “sheet” is also known as a “document-modal dialog”). Its purpose in life is pretty clear: It’s there to let you choose a new template for your new project. Note that the leftmost pane has two sections: one for iOS and the other for OS X.
3In the upper-left corner of the Choose a Template dialog, select Application under the iOS heading (if it isn’t already selected).
After clicking Application, the main pane of the Choose a Template sheet refreshes, revealing several choices. Each choice is actually a template that, when chosen, generates code to get you started.
4Select Master-Detail Application from the template choices displayed and then click Next.
After you click Next, the Choose Options for Your New Project sheet appears.
This Master-Detail Application template provides a starting point for the appropriately named Master-Detail application. What you get is a skeleton app with a split view.
A Split view is what you see in the Mail application. In Landscape orientation on the left is a Master view, and on the right is a Detail view. In Portrait orientation, you see the Detail view with a button that enables you to display the Master view in a popover.
Note that when you select a template, a brief description of the template is displayed underneath the main pane. In fact, go ahead and click some of the other template choices just to see how they’re described as well. Just be sure to click the Master-Detail Application template again when you’re done, and then click Next, to follow along with developing the RoadTrip app.
5In the Choose Options for Your New Project sheet, enter a name for your new project in the Product Name field, and add a company name (or your name) in the Organization Name field. For the Company Identifier, use your reverse domain name (com.yourdomain) if you have one.
If you don’t have one, you can make one up as long as you are not going to be submitting the app to the App Store.
This project is named RoadTrip. (You should do the same if you’re following along with developing RoadTrip.)
Build Xamarin Ios Without Mac
Class prefix is something that will get prepended to the classes the template will generate, so enter RT (for RoadTrip) in the Class Prefix field. Prefixes are most often used to distinguish classes created by different teams so that if they are combined into a single project at a later date, duplicate names are avoided. (These are called namespace collisions.)
6Select Universal from the Devices Family pop-up menu (if it isn't already selected).
Doing so creates a skeleton app that will be configured to run on the iPad, iPhone, or iPod touch.
By choosing Universal, you’re creating an app that can run on iPhone (and iPod touch) and iPad.
Any iPhone application will run on the iPad, but it doesn’t work the other way around unless you create a Universal application.
Select Universal because, with the introduction of storyboards in iOS 5 and Xcode 4.2, creating a universal application has become much easier.
Do not select the Use Core Data check box.
7Click Next and choose a location to save the project (the Desktop or any folder works just fine), do not select the Source Control: Create Local Git Repository check box, and then click Create.
Git is a software control management (SCM) system that keeps track of changes in the code and saves multiple versions of each file on your hard drive. Git can be used as a local repository — thus the Create Local Git Repository for This Project option — or you can install a Git server on a remote machine to share files among team members.
If you want to find out more about Git, check out the Xcode 5 User Guide (choose Help→Xcode User Guide).
After you click Create, Xcode creates the project and opens the Workspace window for the project.

Xcode will remember your choices for your next project.
