I had this error already in Xcode 13 but it still persists
in the current version.
When I connect my iPhone XS to preview my SwiftUI app in the canvas, it shows the iPhone 14 Pro layout. However, when I check on Devices and Simulators, it's correctly recognised as iPhone XS.
So when I design my layout, I always have to switch between the iPhone XS simulator for designing, and my real device for testing.
Does anybody know a way to show the correct device in the canvas?
I have the same issue and I found out that if you want to see the specific device type to canvas, you have to download the simulator for this device.
From the "Windows" tab, choose "Device and Simulators", and then Simulators. At the bottom left of the window, you can add new simulators.
Then choose your device type and download it.
Once you've added a new simulator, you can use PreviewDevice(rawValue: "Your Device Type").
For example:
I added a new iPhone 12 Simulator and use HomeScreen().previewDevice(PreviewDevice(rawValue: "iPhone 12"))
add simulator window
After that, I am able to see my screen as an iPhone 12.
I know that for Android it's possible to use Chrome://inspect to view the phone screen on your desktop. Clicking there is equal to tapping on the phone.
It's fine for browsers and after 4.4 - for apps that have some special lines of code inserted.
Whether it's possible for iPhone / iPad?
i.e. I have a REAL device with latest OS installed, which screen I'd like to be shown on MAC + clicking on the items on the screen will be equal to tappping on the phone.
XCode iOS Simulator - I am somewhat surprised you missed this part of the IDE.
It seems that this is not possible.
I have downloaded xcode 4.5 from ios dev center.(dnt know is it the way).I got a dmg file.when i clicked on it to install it has only one xcode setup is there(nothing like samples,simulator folders which normally has).i inatalled it run my application .but when i got the simulator it has hardware options as ipad,ipad retina,iphone,iphone retina3.5,iphone retina 4 inch.only.the normal iphone simulator has the same screen reselution as 320,480.so the retina display has only the changed reselution screen.Is it correct.Can any body used this can guide me?
If you mean that there is no low resolution Simulator, thats right. If you want a smaller Simulator, you can type CMD-3.
I've read some solutions about this color differences but they haven't worked. I tried taking a screenshot from my iphone and compare it to the simulator image or the image in the prview tool and its the same color, only when I see it on the device it looks different.
I'm using SDK 5.1 on XCode 4.3
How can I fix this ??
Thanks in advance.
OS X System Preferences has a Displays section where you can adjust the screen colors (I don't know whether that's safe to apply others than "Profiles for this display")
You can either try to use another profile, calibrate the screen or to google more taking this preferences pane into consideration.
I just upgraded to iPhone SDK 3.2 Beta 4. Since doing so, I have not been able to get the app to launch in the iPhone simulator - it keeps launching in the iPad simulator. I have tried option-clicking the drop-down menu in the top left-corner of Xcode and setting 'Active Executable' to iPhone simulator 3.1.3 but it keeps going back to iPad simulator instead.
What gives? I have no interest in my app running on the iPad and I don't want to test it in the 2X mode in the simulator.
Thanks,
You can't really launch an iPhone app in 3.2.x - sometimes it will pop up - but basically right now it is only for iPad development.
Update for release version of Simulator.
First of all, the title of this question doesn't match the description: Xcode target isn't the same as the simulator hardware device.
If you are writing an app targeting 3.2, it can run on both iPad (using OS 3.2) and lower OS versions on the iPhone. You do this by setting the Base SDK to iPhone Device 3.2, the Targeted Device Family to iPhone/iPad, and the iPhone OS Deployment Target to 3.1 (lower than 3.2).
The iPhone simulator has a menu option for Hardware->Device, which can be set to iPhone or iPad. However, you can only run a 3.2 SDK target in iPad mode, and a Universal app that supports iPad can only use the 3.2 SDK to build.
You can of course set the simulator to iPhone mode and launch your app from Springboard, but that will lose the debugger connection. Switching mode during installation of your app will cause it to crash.
So the short answer is still the same: you can't run a Universal iPad app in the iPhone mode simulator while debugging.
Upper-left corner of the IDE find a dropdown list of Simulator versions - flipped to 3.2 - try to put it back to 3.1.3
and relaunch your app.
This was driving me nuts too, but the answer is right here:

In short, tell Xcode to Build for the 3.2 SDK, then switch the build menu to the 3.1 SDK and tell Xcode to Run the app. Presto, the app starts in the iPhone simulator!
From Apple's documentation: "iPhone OS 3.2 does not support iPhone and iPod touch devices. It runs only on iPad." There's no way to target 3.2 for iPhone, so there's no Simulator. Ergo, you'll have to wait for iOS 4. Fortunately, that's only 4 days away now... of course it won't support the first generation of iPhone devices, but for all other iPhone users it's a free upgrade. Not sure about iPod Touches.
You should be able to change your target platform in your Project Settings.
Changing the target platform and device makes no difference. It always launches the iPad simulator.
If you switch the simulator to iPhone mode, the app just disappears.
This dev environment is a mess.
Short answer: You can change the hardware setting in the simulator. Hardware->Device
Go to Project
Set Active Executable
There are 2 options: Ipad Simulator 3.2 or Iphone Simulator 4.0.
If you choose the Iphone simulator, then it will launch Iphone simulator.
If you choose the Ipad simulator, then it will launch Ipad simulator.
I finally solved this problem myself.
First, install new version of xCode, which is xCode 4.
Then set project scheme to iphone simulator and run app in xCode several times.
And re-install xCode 3 and the problem will be gone away!
