XCode/Simulator: How to run older iOS version?


I'm thinking of upgrading to iOS SDK 4.2. But what I'm wondering is if I'll still be able to run the simulator as iOS 3.2. This is because I'm creating iAds for iPad but I still want to check if my program will run with iOS 3.2.



Note: I have seen a similar post to this in the past, but they weren't really helpful in giving the exact steps in how this could be done.



Thanks in advance!

  1. If you have iAds in your binary you will not be able to run it on anything before iOS 4.0 and it will be rejected if you try and submit a binary like this.

    You can still run the simulator from 3.2 onwards after upgrading.

    In the iPhone Simulator try selecting Hardware -> Version -> 3.2

  2. To anyone else who finds this older question, you can now download all old versions.

    Xcode -> Preferences -> Downloads.

    Install all the versions you want/need.

    To show all installed simulators:

    Target -> In dropdown "deployment target" choose the installed version with lowest version nr.

    You should now see all your available simulators in the dropdown.

  3. In XCode under Targets, right-click on your project and Get Info. Under the Build tab look for iOS Deployment Target. By changing this you should be able to test different iOS version.

  4. To add previous iOS simulator to Xcode 4.2, you need old xcode_3.2.6_and_ios_sdk_4.3.dmg (or similar version) installer file and do as following:


    Mount the xcode_3.2.6_and_ios_sdk_4.3.dmg file
    Open mounting disk image and choose menu: Go->Go to Folder...
    Type /Volumes/Xcode and iOS SDK/Packages/ then click Go. There are many packages and find to iPhoneSimulatorSDK(version).pkg
    Double click to install package you want to add and wait for installer displays.
    In Installer click Continue and choose destination, Choose folder...
    Explorer shows and select Developer folder and click Choose
    Install and repeat with other simulator as you need.
    Restart Xcode.


    Now there are a list of your installed simulator.

  5. Choosing older simulator versions is not obvious in Xcode 3.2.5. Older Xcodes had separate lists of "iOS Device SDKs" and "iOS Simulator SDKs" in the "Base SDK" build setting popup menu, but in Xcode 3.2.5 these have been replaced with a single "iOS SDKs" list that only offers 4.2 and "latest".

    If you create a new default iOS project, it defaults to 4.2 for both Base SDK and Deployment Target, and in the "Overview" popup in the project's top-left corner, only the 4.2 Simulator is available.

    To run an older iOS simulator, you must choose an older iOS version in the "iOS Deployment Target" build setting popup. Only then will the "Overview" popup offer older Simulators: back to 4.0 for iPhone and to 3.2 for iPad.

  6. The simulator CANNOT be downloaded from:

    Xcode -> Preferences -> Downloads

    Only the iOS devices symbols. As this option says:


    This package includes information and symbols that Xcode needs for
    debugging your app on iOS devices running versions of iOS prior to iOS
    4.2. If you intend to debug your app on a device running one of these versions of iOS you should install this package.


    That is, you need an iOS 4.2 device to test an iOS 4.2 application

Why is this Javascript much *slower* than its jQuery equivalent?

I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...
