# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

# (A similar approach works for older versions too, just change the version number after DeviceSupport)

Low Power Mode - LPM

With iOS 9 Apple added a Low Power Mode to the iPhone. It extends battery life by stopping some battery heavy features such as email fetch, Hey Siri and background app refresh until you can recharge the device.

It is important to understand that it is the user who decides to enter low power mode. You need to go into the battery settings to turn it on.

Detection

To detect LPM you have to be in the couple iOS 9.X / iPhone:

• For iOS 8.X, you need test availablity before use it

Available keys for -exportOptionsPlist:

	compileBitcode : Bool

		For non-App Store exports, should Xcode re-compile the app from bitcode? Defaults to YES.

	embedOnDemandResourcesAssetPacksInBundle : Bool

		For non-App Store exports, if the app uses On Demand Resources and this is YES, asset packs are embedded in the app bundle so that the app can be tested without a server to host asset packs. Defaults to YES unless onDemandResourcesAssetPacksBaseURL is specified.

There are several complaints regarding TeamCity build agent can't run tests in iOS Simulator all gathered in issue TW-38954 Agent started automatically on Yosemite could not launch iOS simulator.

Official workaround from JetBrains found on StackOverflow for this issue looks like this:

$ sh buildAgent/bin/agent.sh start

This means we should convert from automatic launch by launchd to manual via Terminal.app. Side effect of this is no relaunch on agent crash or system reboot.

Further investigation on that issue has led me to the Apple Developer Forums topic where Apple engineer claims following about xcodebuild:
