Why is the Titanium build process so slow?

I have a 2013 Retina MacBook pro and am amazed by the XCode build speed. I can build and run a fairly large Objective-C app in the simulator in about 2-3 seconds.

When building and running a smaller Titanium App for iPhone, it takes about 15 seconds an I am wondering why. In the console, the build process is really fast, but the app hangs for about 10 seconds on "Invoking xcodebuild"

$ titanium build -p ios

Is there anything I can do to make this faster?

Solution

  • I got the hint that lead to the solution of the problem on my Appcelerator QA Question

    The cause of the full build each time was hinted by this line in the logs:

    Forcing rebuild: custom Info.plist CFBundleIdentifier not equal to tiapp.xml <id>

    I have a custom Info.plist in my project which is copied to the XCode project each time. I have changed the tiapp.xml <id> property be identical to CFBundleIdentifier and the build goes through now in less than 4 seconds.
