Install Simulator SDK 4.3 to Xcode 4.4 on Mountain Lion

Question

I want to install SDK 4.3 in xcode 4.4 on mountain lion (os x 10.8), but when I installed the 4.3 sdk package from xcode 4.1 and launched the simulator from xcode 4.4, the simulator just told me that the ios simulator could not find the sdk.

The sdk may need to be reinstalled, which means it couldn't run! What's wrong with xcode 4.4 GM?

Are there any ideas about how to solve this kind of problem?

Answer 1

I've looked into it, and this is a deliberate behavior from Apple.

Here is an (edited) extract of the cache for Xcode download locations:

~/Library/Caches/com.apple.dt.Xcode/Downloads/eded78df8bfabaf6560841d10cf8e53766f74f28.dvtdownloadableindex

<dict>
    <key>source</key>
    <string>http://adcdownload.apple.com/ios/ios_simulator__resigned/ios_43_simulator.dmg</string>
    <key>identifier</key>
    <string>Xcode.SDK.iPhoneSimulator.4.3</string>
    <key>name</key>
    <string>iOS 4.3 Simulator</string>
    <key>userInfo</key>
    <dict>
        <key>InstalledIfAllPathsArePresent</key>
        <array>
            <string>$(DEVELOPER)/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk</string>
        </array>
        <key>ActivationPredicate</key>
        <string>$MAC_OS_X_VERSION < "10.8.0"</string>
    </dict>
</dict>

Note the explicit "ActivationPredicate: $MAC_OS_X_VERSION < 10.8.0" setting, which is not present on other simulator packages.

I tried to edit the file, but it is replaced by another version as soon as Xcode opens. And I couldn't manage a manual download of the 4.3 Simulator DMG: the ADG website throws a "Session expired" error.

Looks like Apple had issues with the 4.3 simulator, and decided to disable it. Which sucks for people that have to support this version.
