The fact that there are two betas indicates to me each will be followed up by an official release. So how? My guess: there will be an official Xcode 6.2 release after Watch release. It doesn't make much sense to skip a minor version. Then things get interesting. Watch is coming out in April. Shortly after that, we'll have WWDC. Usually, WWDC comes with major Xcode beta release. So ... what happens to version 6.3? My guess: either we'll never get Xcode 6.3, or we won't get Xcode 7 this year. The former make sense in the context that <a href="http://9to5mac.com/2015/02/09/apples-ios-9-to-have-huge-stability-and-optimization-focus-after-years-of-feature-additions/">Apple Is Focused on Stablity</a>. Xcode needs some love on that front, let's face it! On the other hand, no harm would be done if Apple market 6.3 as version 7 come WWDC. Afterall, Swift 1.2 is significant enough to justify a major version.

Enough said. What's worse, sometimes I find myself relying too much on auto-completion with Cocoa Touch, a blessing and a curse! So I searched for an alternative workflow in command line. The result was rather confusing: there are posts about using <code>xctool</code> or <code>xcodebuild</code> to build Xcode targets, using <code>ios-sim</code>, <code>simctl</code> or <code>instruments</code> to manage and manage or launch simulators. Most of the information is out of date. Eventually though, I was able to piece together an answer for my needs. That is, given an iOS project set up with Xcode 6, I want to <ol> <li>build a target.</li> <li>launch a iOS simulator.</li> <li>install the built .app bundle to the launched simulator.</li> <li>run the installed app.</li> <li>uninstall the app from the simulator.</li> </ol> All in command line, with Xcode closed. Before we proceed to the steps, you need to gather a few pieces of information: <ol> <li>the Xcode build scheme of your choice (e.g. "AwesomeApp").</li> <li>your app bundle ID (e.g. "com.awesome.app").</li> <li>name of an existing simulator (e.g. "iPhone 6 Plus"). If you don't want to look it up in Xcode GUI, look for it in output of command <code>xcrun simctl list</code> .</li> </ol> Ready? Here we go. (These commands should be run in the project folder). Build the target: <pre><code>xcodebuild -scheme AwesomeApp -destination 'platform=iphonesimulator,name=iPhone 6 Plus' -derivedDataPath build </code></pre> Launch the simulator: <pre><code>xcrun instruments -w 'iPhone 6 Plus' </code></pre> Install the bundle (after simulator is launched and target is built with previous commands): <pre><code>xcrun simctl install booted build/Build/Products/Debug-iphonesimulator/AwesomeApp.app </code></pre> Launch the app in simulator (after it's installed with the previous command): <pre><code>xcrun simctl launch booted com.awesome.app </code></pre> Uninstall the bundle: <pre><code>xcrun simctl uninstall booted com.awesome.app </code></pre> Quite a few parameters needs to be added for the build step if you have a comlex project. Please RTFMs. Write some script to automate the steps, if are a lazy typiest like me.
