    3 Solutions Collect From Internet About “Application Failed to Launch in Time”

    You’re probably doing a lot of setup work in your AppDelegate’s application:didFinishLaunching method.

    You should make sure this function exits as soon as possible. Any setup-work that takes time (network access for example) should be done asynchronously in your application. While this is going on, you can show a spinner to indicate to the user that the application is loading.

    In order to add so information to Philippe Leybaert response.
    If the application take to much time to start the main thread will be kill so the application will crash.

    • When you’re using the simulator, it will not crash.
    • When you are using your iphone connected to xcode it will not crash.
    • When you send it for App Store it might be accepted if the Apple tester is using a fast iPhone
    • When your users on slow like iPhone 3S will crash

    A way to test this issu before submitting is to deploy to testflight or with adhoc and install it on the slower device you want to support.

    Just try to divide your application:didFinishLaunchingWithOptions: method code to different function calls and make those calls in background using the threads other then main and make sure that application:didFinishLaunchingWithOptions: method returns as soon as possible

    you can use

    dispatch_async(dispatch_get_main_queue(), ^{
    //put your code
