I have been looking around for learning how xcode can be used for jailbreak development.
I have Lion and jailbroken iPhone3G and xcode4.6 which doesnt support iPhone3G.
I have installed ldid but have no idea how to use it.
I have to make launch daemons, too, and attach them with my application. I have followed this tutorial for making a daemon but i got stuck in the setup for creating an open tool chain template in xcode. I followed every step but my xcode is not showing any template for open tool chain. Is it really required to have open tool chain template?
You're right. Xcode 4.6 doesn't support the iPhone 3G. Can you install an older version of Xcode? For example, Xcode 4.4 still supports the 3G.
Login to the Apple Developer Portal and download old versions here
You can choose to install the old version of Xcode in a different folder, so that it doesn't overwrite the new version (for example, install to /Developer-old/ or something).
Once you install the old Xcode version, you can navigate to the installation directory and look for the directory named:
iPhoneOS5.0.sdk
(or probably iPhoneOS5.1.sdk would work, too). Then, copy that entire folder into the new Xcode 4.6 installation directory. For example:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
Afterwards, you should see this:
iPhoneOS5.0.sdk
iPhoneOS6.1.sdk
With the 5.0 SDK installed, you can now build apps for the iPhone 3G, using Xcode 4.6. You can also now uninstall Xcode 4.4 if you want. See more about this in this other question. The key is that you will be building your app for armv6 (only). Armv6 is the iPhone 3G's processor.
The second step is to turn off code-signing within Xcode. In your project settings, you set the provisioning profile to Don't Code Sign. You must modify an Xcode configuration file to allow you to do this.
Now you build the app in Xcode. When you're done, navigate to the directory on your Mac where the app has been built (where the MyAppName.app/ folder is). Then, you use ldid to fake code sign the app executable:
ldid -S MyAppName.app/MyAppName
Now, your app has a fake code signature that will allow it to run on a jailbroken phone.
Then, you use ssh, or scp, or something else to transfer it to your phone, where it should be installed under /Applications/.
You already have the best link on building iOS Launch Daemons. I'd stick with that tutorial. No, I don't have any open toolchain template in Xcode, either. I just use Chris' tutorial to see how to build a non-graphical daemon main program (not a UIApplication), copy it to my MyAppName.app folder, and create a com.mycompany.mydaemon.plist file that defines the Launch Daemon.
Once the plist is installed in /System/Library/LaunchDaemons/ on the phone, you can start it, without having to reboot the phone, with:
launchctl load -w /System/Library/LaunchDaemons/com.mycompany.mydaemon.plist
at the command line (on the phone). Or, just reboot the phone, and the daemon will start automatically.
Although I learned to do this before it was available, you can now look at iOSOpenDev if you'd like a more polished way of doing some of this stuff.
Yes. Xcode can be used for developing jailbreak-type projects. Use iOSOpenDev to set up Xcode and iOS SDK to allow jailbreak-type development.
iOSOpenDev comes with a set of templates, signs (with ldid) targets and creates Debian packages (packages are submitted to repos like ModMyI and BigBoss) during its build phase, in addition to installing packages directly to an iDevice with Cmd-Shift-I (build for profiling shortcut) for immediate testing, among other useful features for using Xcode to develop jailbreak-type projects.

I want to know how to install an ipa/app file into iPhone just using the command line?
The device maybe without jailbreak or jailbroken already.
I tried to use the command line: xcodebuild, but failed. I didn't find the parameter how to set the destination, maybe a real device, not a simulator.
What options do I have?
Three ways I know of:
These guys wrote a tool in Ruby to do it. It uses the Fruitstrap library which in turn uses one of Apple's private APIs, so this could possibly break in the future.
You can also just use Fruitstrap on its own, but then you need an .app directory, whereas the Transporter Chief tool I linked above supports both .app and .ipa deployments (as required in your answer).
In either case, you need to have XCode installed for it to work, but the device does not need to be jailbroken.
Thirdly, there is also a binary distribution for OS X of the libimobiledevice library, which enables Linux boxes to talk to iOS devices. This has a few different tools, one of which can install valid signed IPAs to the device using this syntax:
ideviceinstaller -i myapp.ipa
The advantage of this method is that it does not need XCode or even iTunes.
With the new Apple Configurator 2 application, you can Install Automation Tools... from the menu. This will add support for the command-line tool "cfgutil".
cfgutil allows you to install ipa's from the command-line using cfgutil install-app <AbsolutePathToIpa>. We use it on our build server to automatically update the device with the latest build.
I've just gathered in a single post (Gist) how to achieve this, using
1.- Mattt's library Shenzhen
2.- Phonegap's library ios-deploy

How to generate and install an IPA file
I've tried libimobiledevice-macosx. works fine on iPhone 5. iOS version 6.1.4.
I was able to install app and see log output like in xcode :) Thank you!
I am trying to simulate an upgrade from version 2.0 to 2.1. I have version 2.0 hosted in testflight, so I did install it in my device. Then I tried running the app from xcode. However what happened is that the app did not get overlapped, instead it created two apps with the same name. How can I make it such that when I run the app from xcode it overlays the old version?
I've made sure that the bundle identifier is the same.
Well the info you can get while updating can be found # this link here.
when user updates an app, Documents folder is stored as is, including
NSUserDefaults (but, sometimes user download app via iTunes and
replace the whole application, crying 'OMG! update killed all my
levels progress!'); Application bundle is erased and replaced by new
one (anyway, it is readonly for user); Re-deployment of new build
version will be enough;
You can't access the appstore inside the simulator because: # link here
It's a simulator not an emulator. Even if there was an App Store in
the Simulator, none of the apps in the store would work since they are
compiled for ARM CPUs while the Simulator runs x86 code.
Another stack overflow # link here states:
Build and install your old version, generate some data, and then
install the new version on top of it.
For testing before submitting to the Appstore I generally download
from the AppStore again the old version, and then install with Xcode
the newer version - for your next update... ;-)
And another stack overflow (that I lost the link for) states:
No, the simulator runs i386 binaries and iPhone appstore apps are ARM
binaries apps.
iOS apps are compiled to machine code, Android apps are run in a
Virtual Machine using byte code and are translated to machine code at
the time they are run.
So no, I don't believe you can run it in the simulator, how ever you can have older projects saved on the iPhone and test both out. And the apple documentation is # this link here.
Read this: https://developer.apple.com/library/ios/technotes/tn2285/_index.html
You cannot simulate update in XCode (neither in simulator or connected device). You have to create IPA file and simulate update process via iTunes.
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 am developing an iphone app using xcode. I would like to automate the "build and run" process, and so want to know if there is any way to install the built app on simulator or device.
There is xcodebuild install command but i don't know how to set the installation directory DSTROOT to simulator/device. Please help me there.
I have looked through many forums where people suggest just to use xcode GUI to do the stuff, and I do that too, but I would really like to know the command-line way.
Thanks
All you need to do is copy the built .app from wherever XCode puts it to ~/Library/Application Support/iPhone Simulator/User/Applications/[somefolder]/, with a file named [somefolder].sb (alongside the folder, not in it) containing the following:
(version 1)
(debug deny)
(allow default)
Then launch /Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator. And select your App. Without Jailbreaking it's NOT possible to install it from outside the GUI.
The install build action for Xcode will only copy the built product to the install path specified in the xcode project.
This is used for frameworks and libraries that need installing after being built so that other apps can link against them from a common location.
I don't think you'll be able to use this build action to automate the Build and Run process - that is going to have to be done manually by each developer. There is no way to push apps onto a device without using Xcode, iTunes or the iPhone Configuration utility. As for the Simulator, it's as woodleader says. But for the device, without jailbreaking and writing your own code, you can't do this.
What you can do is use xcodebuild to generate daily/nightly builds for continuous integration. You can write a script that checks out the source form version control, runs xcodebuild and puts the built product in an easy to reach location. The installtion onto devices will still need to be done manually however.
I am working on a project using iOS3.2 SDK and also want to test my app in iOS4.2 beta.
So I installed Xcode and 4.2 SDK but it replaces previous Xcode installation. Up until now it was ok since I was not busy with these two things. But now I need both.
How Do I change Xcode (with iOS SDK 4.2) install destination?
I was expecting a button "change install destination" during install but only installation disk partition is changeable. (No folder can be chosen).
Is this possible?
Yes, you missed it in the installer because they made it hard to find. Once you pick the volume (your hard drive), you can Customize the installation, which lets you specify a location (/Developer-Beta or whatever you want). Unfortunately, you'll now have to reinstall other one again.
