i was add a new target in my existing project.
Everything work fine, but... this warning is become.
Mac OS X Deployment Target '10.6' is newer than SDK 'iOS 4.2' in target snow iphone
Anybody knows how i can disable it?
XCode4 is different and I had trouble finding this option. Here is how to do it - to access the Base SDK for the project, select the project (blue xcode icon) in the navigator top-left; select project properties (not targets) in the next pane; then select "Build Settings".
I tried to post a screenshot but apparently I need to earn more "reputation points" first...
I know this is an old question, but I ran across the same issue and want to provide help. The warning means your version of Xcode is using an SDK older than your deployment target. For example, you have Xcode 6.2 but are deploying for iOS 8.3. You would need to update Xcode to version 6.3 to resolve that error. Another option is to simply download the SDK manually from the Apple Developer center.
Right-click on your target and select Get Info. Go to the Build tab and ensure that the Base SDK setting is Latest iOS.
go to target settings and make sure that Base SDK is set to the latest one. Also check the deployment target.
I hit this problem when I accidentally opened my older version of Xcode. If you have 2 versions of Xcode installed on your computer, make sure you are using the one you intend to! The older version won't understand a newer deployment SDK.

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 have iOs version 3.2.3 version. now i have installed 4.2 version in my system but when i open my xcode it shows the previous version of iOs...
Even when i go and edit the project settings, i dont get the 3.2.5 version in the drop down to select.
why this happening...
please help me out
That version number is actually the Xcode version number, not the iOS version number. Select "About Xcode" from the Xcode dropdown, and you'll see 3.2.5.
If you want to change the iOS version to the new one (I'm guessing 4.2?) try opening up the Target Info (or the Project Settings), and setting the Base SDK to the version you want. (You can also set the Deployment Target to the minimum version you want to support, as discussed here.
Once you do this, select the new SDK from the dropdown menu at the top left, and you should be good to go.
Please open Xcode then from
Xcode-> About Xcode ->Version 3.2.5 (Check out the version here)
If its still not showing please check out whether the xcode setup is successfully done. Try rebooting your mac.
P.S: For Installing Xcode 3.2.5 you need to update your Mac OS to 10.6.5
Also iOS version number will be 4.2 and not 3.2.5 i.e your iPhone/iPAd version whether be device or simulator.. So in dropdown if you see 4.2 then your setup is done successfully..
hAPPY iCODING...
Looks like you have two installations of SDK and XCode on your machine. This can happen if you have changed the installation location while installing the SDK. Hope that helps.
I recently installed XCode 3.2.4 to my machine. This comes with iOS SDK 4.1. Annoyingly I can no longer install my app to any iPhone. The option to tick "Device" in the drop down for where to install to is present, but when I click it, it doesn't become ticked. Strangely I can only run my app on the simulator, despite the option to select the simulator not being present.
Does anyone know how to fix this or what might be the problem?
Thanks in advance,Tristan
Alrighty, I'm answering my own question.
What I didn't realise is that there's seperate build configurations depending on wether you click 'info' while selecting your project's title or the project's Target. I had set the project one to SDK 4.1 but not the Target one.
Did you set the iOS Deployment Target in your Debug or Release Build Settings to match the OS version on your iPhone? Did you set the Targeted Device Family to iPhone?
All these questions just remind me that something is very confusing in xCode.
And don't let me start talking about all the provisioning misunderstandings
Why are old SDKs beeing removed when installing a new version of xcode with new Iphone SDK ?
Now we have v4, what settings do I have to make in order that the apps still work with 3.x ?
Thanks
Set the Base SDK to 4.0 and Deployment Target to 3.x. Or, in modern conditions, the Base SDK to Latest and Deployment Target to whatever you need.
Although 'Zoul' has most succinctly answered the question, I shall make an attempt to elaborate on the 2 settings and point to some useful documents which will help others who are new to the situation.
Base SDK Version: This indicates the version of the SDK based on which the program has been compiled. This can be set from the "Build Settings" for the project or target. You can use API code from Apple in your code introduced up-to that version and compiler will know all the symbols and compile without any issues.
Deployment target: This is a declaration from your side about the minimum iOS version which should be installed on the user's device to run your code. This setting can be found under "Info" section for Project and "Summary" section for a particular target. Now, important thing to understand is that your code will not automatically run smoothly on devices with older versions of the iOS if you are using API code introduced in later version by Apple. These can be new classes/methods/frameworks introduced by Apple in later version. You have to ensure by writing necessary conditional code and provide alternate code path to gracefully degrade for older iOS version which does not have the newer API. It is up-to you to handle version incompatibilities.
Apple documentation on the subject can be found in "SDK Compatibility Guide".
To know about the changes with different versions of iOS refer "What's new in iOS".
This topic is also discussed in "iOS Development Guide" under section "Building and Running Application". Refer sub-section "Specifying the Runtime Environment".
If you have backups of your system from something like Time Machine (and you better!) you can copy the older SDKs from the backup located at /Developer/Platforms/iPhoneOS.platform/Developer/SDKs and /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs - then just restart XCode and you're ready to go.
If you still have the problem after you set Deployment target at least as low as your desired SDK, then you need to download that SDK. Luckily, Xcode helps us here also:
look after Simulator selector in top left of your Xcode and select More Simulators. It will open a page like the one below:
just select the SDK you need to test your app against.
3.2.3 last beta did remove all other SDK's cause to many people tried publish Apps developed with the beta SDK, which will not be accepted. I guess GM is doing still the same
If you want to develop for 4.0,3.2 and 3.0 (plus 3.0,3.1,3.1.2,3.1.3)
do the following
sudo /Developer/Library/uninstall-devtools –mode=all (This will uninstall the current XCode installation)
Then install first old XCode (3.2 final) in default folder (/Developer)
Then install the new XCode (3.2.3 GM) in other folder (/DeveloperBeta)
This way you will have both. And can launch xcode from either /Developer/Applications/Xcode.app or /DeveloperBeta/Applications/Xcode.app
I upgraded to Xcode 3.2 and now can't seem to add a number of frameworks, specifically the media player. A number of frameworks do not show up on the "Add Existing Frameworks Sheet".
Per another question I tried setting the "Framework Search Path" to
$(SDKROOT)/Library/System/Frameworks
but that didn't seem to make any difference. The UIKit.framework that is included by default when I create a new project is in
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.sdk/System/Library/Frameworks
which I would expect. If I navigate to that directory I see the MediaPlayer.framework and can drag and drop it into my project successfully, but can only build and debug for a device-no suprise there, but not ideal.
I uninstalled the dev tools with
mode=all
and reinstalled Xcode, but still no relief. Any help would be greatly appreciated.
Your project was probably configured to use an older SDK that's not included in the Xcode 3.2 + iPhone SDK package. Go to your target's Get Info panel, Build settings, and set the Base SDK to an SDK that's actually installed.
If you want your app to run on older iPhone OSes, set the iPhone Deployment Target build setting to the earliest OS you want to run on.
I just had the same issue when upgrading to 3.1.2. One thing you will want to do is open your Xcode Project, right-click on the project and Get Info... Then change the Base SDK for All Configurations to (the minimum of) 2.2.1.
When I did this it re-linked all of my RED (missing) Frameworks. Cheers!
I know this question is over a year old, but I just had a similar problem and solved it by looking for the missing framework in the trash and putting it back.
I must've deleted it by accident!
Possible Solution 1: Clean Your Project
Build > Clean All Target
Possible Solution 2: Make Sure Your Device is in Correct Firmware
To debug, read console log.
Hope it helps.
