There are some features of iOS apps that don’t work from the iOS simulator. Maybe you want to test how your application works with the device camera or send an SMS message from your application. For these examples and more you’ll need to test and debug your app using a real device.
This post will walk through how to run the Xcode simulator on your iPhone or other iOS device and show you how to fix some common errors you’ll see along the way.
If you’re an iOS developer and you’re curious about learning the basics of becoming a Mac developer so you can start migrating your iOS apps to the desktop, this tutorial is for you. In this tutorial, you’re going to build your first Mac application, specifically a Mac version of the app we created in the How To Create A Simple iPhone App. 10 hours ago Darkroom for Mac and iOS can be downloaded from the App Store.

Unless you have the raw source code from Apple, you won't see the App Store on the Simulator. The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account.
How to select your iPhone as the “Simulator” Device
Simulator is in quotes here since this will create an actual app on your phone; it’s no longer a simulation. Best mac app photo free studio effect. Open up a project in Xcode and click on the device near the Run ▶ button at the top left of your Xcode screen.

Plug your iPhone into your computer. You can select your device from the top of the list.
Unlock your device and (⌘R) run the application. You’ll see Xcode install the app and then attach the debugger. The application should pop up on your phone.
Troubleshooting Common Errors
The first time I tried to connect my iPhone to Xcode it didn’t work. According to my best friend, Stack Overflow, I’m not the only one who has had issues. Let’s share the fixes to some common errors you might encounter.
“Signing Requires a Development Team”Xcode requires that you’ve connected a Team to your project in order to run the simulator on a device. You can do this from the “General” tab of your Project Settings. As of Xcode 7 this can be any Apple ID.
Open the Team menu that currently says “None” and select your team. If you don’t have a team, select “Add an Account…” and create one with your Apple ID.
Xcode claims your device is locked when it isn’t
This fun bug has been happening since at least Xcode 6. There are a lot of potential solutions in this Stack Overflow post. Here’s what worked for me:

The unsatisfying answer for this one is to just wait.

That worked for me, but a lot of folks had luck with “Solution #3” from this Stack Overflow post.

Every time developers come up with an idea for an app they face the eternal question: Which platform should we build it for, iOS or macOS? After all, resources, especially in the beginning, are constrained and no one wants to risk spreading themselves too thin by working on two products at the same time.
In most cases, the decision comes down to pure numbers: There are over 1.3 billion active iOS devices against 100 million macOS ones. So iOS usually wins. But even though you can build progressive Mac apps with WebView, nothing beats a native Mac app for user experience and speed. Finally, with Apple’s announcement of Project Catalyst at WWDC 2019, you don’t have to compromise any longer.
What Is Project Catalyst
In a nutshell, Project Catalyst is a new macOS Catalina feature (out of more than 120) by Apple built into the latest Xcode 11, which allows developers to extend their existing iOS apps to macOS using all the native Mac functionality, such as mouse and keyboard navigation, window and file management, rich text editing, etc.
To try Project Catalyst today, download macOS Catalina first. Note that not all apps are eligible for iOS to macOS transfer. How to know which are which?
iOS app criteria for Project Catalyst
Apple made sure that most iPad apps would have no problem transferring to macOS. But there are a few exceptions. First, if your app relies on features that are exclusive to iPad, it might not operate correctly on Mac. Some examples include using gyroscope, accelerometer, back-facing camera, HealthKit, or ARKit.
In general, Apple says that if the app supports the latest iPad functionality, such as multitasking, drag and drop, as well as keyboard shortcuts, porting it to Mac shouldn’t be a problem.

Benefits of using Project Catalyst
Currently, there are two approaches to building apps on Mac. Either you create something natively or use WebView. The first approach requires a completely separate codebase; the second, a functioning web app and results in slower user experience in the end.
Project Catalyst combines the best of both worlds. It lets you create completely native apps while retaining exactly the same codebase you had in iOS. Basically, at the flip of the switch, you get access to macOS features like:
All in all, using Project Catalyst would save you days, or even weeks, right from the beginning and an immeasurable amount of time you’d otherwise spend maintaining separate codebases in perpetuity.
How to start with Project Catalyst
Once you’re running macOS Catalina and have Xcode 11, turning on Project Catalyst is a breeze:
The new Mac app shares the same codebase, frameworks, resources, and runtime environment as your iOS app. As you continue to enhance and optimize your project, compatible changes will appear in both versions.

If you need some feature inspiration, check out the newly released Project Catalyst apps created by the teams at Twitter, Jira, and TripIt. But before you start building the new app in a new macOS Catalina environment, make sure your Mac is running at top speed.
Make sure your Mac is bug-free
Developers know that every time you change any variables around your app, unpredictable things might happen. The best you can do is ensure your Mac hasn’t carried over any bugs accumulated in years of use. The fastest way to do this is using a professional optimizer:

The Maintenance scan will ensure your Mac is not laden with everyday inefficiencies. However, if you feel like your Mac needs a deep, overall optimization scan, CleanMyMac X can help you here too:

Now that your Mac is free of bugs, resource-hogging cache files, and unresponsive processes, you’re ready to take full advantage of Project Catalyst. Port your iOS app to macOS in no time and remember to scan regularly (about twice a month) with CleanMyMac X to make sure all processes run as smoothly and quickly as possible.
