I have installed the new 3.0 SDK, but when I start up Xcode, I don't see an option to build for "Device - iPhone OS 3.0" or "Simulator - iPhone OS 3.0"
The Xcode About box says I am running: 3.1.2
Is there something else I have to do?
I think you need to upgrade to Xcode 3.1.3. I have the latest version and that's what my About box reads.
If you are sure you downloaded the latest version, perhaps you installed in to a different location?
If you are using an existing project you may have to tell your project to build to the 3.0 targets. I didn't have to do this for any of my projects but ...
Under the Deployment section of your project properties you should see:
iPhone OS Deployment Target - (change this to use iPhone OS 3.0)
You can also check that the Architectures section has the Base SDK set to 3.0.
This happens quite often when downloading Apple's sample code projects which are targeted for iOS 3.x but you've got iOS 4.x.
To show Simulator option go to Project Info window -> General tab -> Base SDK for All Configurations - choose Latest iOS.
If it doesn't appear straight away, close and reopen Xcode.
This is what worked for me:
I clicked on the box (where I expected iPhone Simulator to be shown), right clicked manage scheme. After that deleted all schemes, and in similar way, created a new scheme. It automatically produced all simulators including the ones for devices.

When I click my iPhone into the USB port, I hear the clicking sound and on my project it shows checking dd symbols and a little progress bar appears. But, when I click on the drop down list, upper right hand corner, my device does not show up, still says any iOS device. When I click debug, a box comes up saying xcode cannot run using using the selected device.
"No provisioned iOS devices are available with a compatible iOS version. Connect an iOS device with a recent enough version of iOS to run your application or choose an iOS simulator as the destination"
I checked to see what sdk version my project was using, it is 5.1.
On the organizer it says my iPhone is using software version 5.0.1.1,
Questions,
Do I have to upgrade my iPhone to 5.1?
I went to iTunes to upgrade it and they only had a option for 5.1.1, if I upgrade it to 5.1.1, will it still work with my xcode which has sdk 5.1 not 5.1.1
Any idea how to get my iPhone to work with the new projects created?
Also, the old projects are using sdk 5.1 and they run fine, could it be a different problem?
Just set the "Deployment Target" for targets and project to your device version.
To do this, click the project in the navigator -> info for project and summary for targets. There you find the deployment target.
Hope this helps
Try run a any XCode 3. And open him Organizer. Then will show a question about Collecting device. Press and reconnect a device. Must help. This helps in my case :)
According to the documentation should be able to choose which iOS version the simulator should run, however only the latest 4.3.2 is listed under "Hardware/Version".
The helps says:
"To set the iOS release used in the simulation environment, choose Hardware > Version, and choose the version you want to test on."
I don't want to support 3.x (although it would be nice) but at least I want to simulate my app on 4.2, 4.1 and 4.0.
What's going on? Why aren't they listed?
UPDATE:
I'm on Lion so I cannot install an earlier version of Xcode. Before my Upgrade I could test different versions easily.
the problem is that you have no other Simulator SDK installed which can be used. As #dorada has mentioned you have to install an older Xcode which in fact doesn't work because you're using Lion. I haven't tried it with Lion but principally it should work like before with Snow Leopard.
I'm referencing to my other answer how to get an older Xcode (don't know if it's still working)
After you have an older Xcode version, mount the image an navigate with terminal to that volume. There should be a hidden folder Packages. open that folder with open . and locate the two .pkg files you need (e.g. iPhoneSDK4_0.pkg and iPhoneSimulatorSDK4_0.pkg) and install both.
They will appear in your root directory and you have to move them to your Developer dir (don't simply overwrite, it will delete all other SDKs. go to the last different folder it should be iPhoneSimulator4.0.sdk\ and copy that one)
DONE (and at that point I have verified it: it works on my Lion. I used the dvd image which I have started backup'ing since 3.2.1)
Although iPortable has the correct answer I decided to post a step-by-step guide which is easer to follow:
Download Xcode 3.1
Mount the dmg file
In Finder menu select "Go\Go to folder" and enter "/Volumes/Xcode and iOS SDK/Packages"
Install the simulators you need (Double click)
Copy the simulation folders from /Platforms/iPhoneSimulator.platform/Developer/SDKs/ to /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
If your have some SDK missing Install the missing SDK from "/Volumes/Xcode and iOS SDK/Packages" and copy subfolders from /Platforms/iPhoneOS.platform/DeviceSupport/ to /Developer/Platforms/iPhoneOS.platform/DeviceSupport/ (for me they were all there from 3.1 to 4.3)
you may download the older ios sdk / xcode from . https://developer.apple.com/downloads/index.action
(i found this answer in another stack overflow topic actually, but now i can not seem to find that question!)
Open Xcode and in the menu at the top left, where you select what device to run on, click "More Simulators..."
The download section of Xcode preferences will open,
Click the "Components" tab.
You will see a list of simulators that can be installed, click install on version you need.
The simulator will need to restart to install.
To run the newly installed version of the simulator just select it from the run menu in Xcode.
You actually have to install previous simulator versions, they aren't there on a new install.
Maybe you can search and download them somewhere? - we keep them on a shared drive at the office.
After installing the Xcode 4.2 for Snow Leopard, I noticed there was a choice for iPad 3.2 Simulator, but using it just brings up some alerts that say "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." and another alert that says "Simulated application quit. Click Relaunch to try again." with Quit, Switch SDK, and Relaunch buttons.
I can successfully use iPhone 4.0 Simulator, iPhone 4.1 Simulator, iPad 4.2 Simulator, etc up to iPad/iPhone 5.0 Simulator, but really would like to have iPad 3.2 Simulator and iPhone 3.1.3 Simulator and earlier down to 3.0 if possible.
Our apps generally run all the way back to 3.0 and we occasionally receive bug reports from earlier iOS users, and would love to be able to debug these issues more effectively.
I tried the technique summarized by Tibidabo and although I am able to copy the simulator folders as mentioned, and though they show up as choices in Xcode, I cannot get them to actually run as simulators and I get the same problem alerts mentioned above.
What are other developers doing to support debugging of older iOS versions?
Go to Project Settings -> Summary an change Deployment Target.
I can't for the life of me find out how to run applicaitons on a device (specifically, and iPhone 4) using XCode 4.
The documentation says to "Set the run destination to iOS device in the scheme editor and build and run your application."
The dropdown menu in the schema editor only has simulator options.
Could someone present a step-by-step method for running applications on devices using Xcode 4?
Using:
Xcode 4.0.2 (iOS 4.3)
iPhone 4.3.3
UPDATE
I ended up doing a series of restarts (Macbook Pro, iPhone 4, Xcode), did a few cleans and builds of the project, and set the "Base SDK" build attribute for the TARGET to "Latest iOS (iOS 4.3).
After that, the device appeared in the destination drop-down in the scheme editing menu.
(Thank you for your time septi!)
Be sure to Verify the BASE SDK used in your project. From the docs:
"
Note: If you are building to your development device, the Base SDK version number defined on your Xcode project must be greater than or equal to the software version number on your development device; otherwise Xcode cannot initiate a debugging session with the device. In that case, you will need to download and install the latest iOS SDK version that is greater than or equal to your device software version.
"
I had a similar problem. My phone has iOS 4.2.1
I downloaded a sample app and my phone did not show up as an option, only the simulators were listed.
So this is just a configuration issue:
To fix this you need to select the project, and:
(as noted above) Select Build Settings/Base SDK = (in my case) Latest iOS (iOS 4.3)
Select Summary: Devices: iPhone
Select Deployment Target: (in my case) 4.2
Now I get the following in the dropdown list of targets:
Myiphone (4.2.1, overriding Base SDK to 4.3)
Also watch out for the UIRequiredDeviceCapabilities property in the plist file. This can prevent a device from showing up sometimes.
I encountered this today in XCode 5 and tried the steps specified. Eventually, I found another solution that may be of use to future readers (Xcode 4 or otherwise).
Go to your project settings and select your target.
Select the "General" tab and scroll to Deployment Info.
Under "Deployment Target", make sure that your device's OS, or something lower, is specified.
---> Your device should now show up as available for debugging in the listing.
Came across this by checking the same device in another project. In that project, the device was listed just fine. When looking at the project settings between the two, the above difference was what stuck out and resolved the issue.
The "Deployment Target" in the project general settings needs to be <= your device, as Danny said above.
Be aware that when you create a new project in a new version of XCode, the default deployment target will be the latest OS release. If your iPhone is on a lower release, this means you either need to upgrade your iPhone, or install an older SDK into your XCode.
You can install an older SDK by copying it into the XCode package at location:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
I was using xCode v3.2.3 and SDK 4.0 to write iPhone apps that worked on my iOS v3.1.3 device... as well as v4.0. (Deployment target set to 3.1.3. Base SDK set to v4.0)
Does that mean everyone that uses my app will need a minimum of iOS 3.1.3 and a maximum of v4.0? Or will they also run on v4.1 and v4.2?
Second part of my question:
I now upgrade my iOS v3.1.3 to v4.2.1.
Xcode now says my v4.2.1 device is now no longer provisioned.
Doesn't a Base-SDK setting of v4.0 mean apps will also run (or at least install) on v4.x?
No. Base SDK just means that your app will be built against the iOS 4.0 libraries. Any 4.x device will be able to run a release build of your app, but for debugging, Base SDK and the iOS version on your device must match. In the end, you need to build your app with the newest available Base SDK anyway, because Apple won't accept apps built for older SDKs into the App Store.
No, they will. iOS has Backward compatibility.
I agree with Irene. I found the solution:
The hint came from here: Can't make Xcode 4 run a barely empty project using SDK 4.2 (runs fine in 4.3)
And this is how i resolve: my xcode 4.0 my SDK 4.3 and my Ipod touch device is 4.2.1 - You see it is backward compatible. There are 2 things you must do in order to resolve. 1) In your xcode 4.0, You click on your project name under Target to ensure you change the target not the Project setting. Find the row >IOS deployment target to the version of your device in my case it was back to 4.2.1 ipodtouch so i set 4.2 (do not worry about basesdk it is for your application not the same as your application's target. 4.3 basesdk requires you provide codesign so you have to select code sign if do not have one apply for one looking up in Apple website or google)
After setting your target to compatible version with your device you now can go to "set the active scheme" that is where you select which device to install and run on including the simulator. So you will find you device there select it and you are good to go.
And if you still can not get it going. You can try to select your project under Project this time adn set the ios deployment target to your version mine was 4.2 ipodtouch ios. Then go select "set the active scheme" that is where you select which device to install and run on including the simulator. So you will find you device there select it and you are good to go.
I've downloaded the final version (and never installed any beta versions before) of xcode 3.2.3 with sdk 4, and now I can't seem to find a way to compile my app for a 3.1.3 iOS.
Does anybody know how can I do that ?
As it is, you can't. They probably did this on purpose to discourage new apps compiled for 3.1.3 which foils multitasking.
Instead you can compile for iOS 4 but make your deployment target 3.1.3. This doesn't really require any more real work, as long as you don't use any non-3.1.3 methods/classes etc. and the application can install and run on a 3.1.3 device. You can also then make your application multitasking aware so that it works nicely on a device that does run iOS 4 and is capable of multitasking.
Just a note: the Base SDK may be set at the project level, but you will need to go to the build settings for the target itself to set the deployment target (that setting is not available at the project level).
To expand on Jason Coco's answer:
If you go to the Project Info screen and click Build, you can choose what Base SDK to use (4.0) and then scroll down to iPhone OS Deployment Target version and set it to 3.1.3 or whatever.
However, you also have to go to the Targets section under Groups & Files (red bullseye) select your target and get the Info build page, and set your iPhone OS Deployment Target there too.
Once that's done, you should be able to test it with a device that's still running 3.0 or whatever you selected.
if you want to be compatible with iPhone OS 3.x you still compile for SDK 4.0, but open target settings and choose that application can run on 3.x (iPhone OS Deployment Target). If you did not use any iOS 4.0 specific APIs then your app will run smoothly on 3.x and 4.x, here is a screenshot of setting to change:
