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.

Solution 1:

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

Xcode -> Preferences -> Components (Click on Simulators tab).

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.

Solution 2:

XCODE 10.1

1. Goto Xcode -> Preferences (Shortcut CMD,)

2. Select Components

3. Download Simulator version

4. XCode -> Open Developer Tool -> Simulator This will launch Simulator as stand alone application

5 Hardware -> Device -> Manage Devices...

6. Click on + iCon to create new simulator version.

7. Specify Simulator Name, Device Type and Choose OS version from drop down.

8. Click Create.

9. Hardware -> Device -> iOS 11.0 -> iPhone 6

Thats it run enjoy coding!

Solution 3:

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

Solution 4:

Open xcode and in the top menu go to xcode > Preferences > Downloads and you will be given the option to download old sdks to use with xcode. You can also download command line tools and Device Debugging Support.
