The problem is that this kind of UIAlert appears before Instruments can take control of the app.

In some cases, applications that ask for location services, access to contacts, access to photos, etc, immediately after the app is launched are violating the Mobile HIG guidelines.

Quoting the HIG

Ask permission at app startup only if your app can’t perform its primary function without the user’s data. People will not be bothered by this if it’s obvious that the main function of your app depends on knowing their personal information.

Avoid making programmatic calls that trigger the alert before the user actually selects the feature that needs the data.

1. When targeting a Simulator, the app launches, then quits several times in rapid succession.

The problem is that the binary in incompatible with the simulator version.

For example, if you build an app iPhone 6 Simulator it will contain an x86_64 instruction slice. You can install this binary on an iPhone 4s simulator, but it will not launch because the iPhone 4s Simulator because that simulator requires an i386 instruction set. Simply put, you must build an app that is compatible for the simulator you are targeting.

Here are some steps you can take to solve this problem.

Make sure you have the latest version of calabash and the latest version of the framework. [1] If you are not using bundler already, now would be a good time to start. [2]

We want to merge the Calabash Android and iOS gesture APIs.

Calabash Android has a three options that can be passed to a gesture:

x => a percentage; how far away from the top-left corner on the x-axis to perform the gesture
y => a percentage; how far away from the top-right corner on the y-axis to perform the gesture
offset => {:x, :y} - how many points from the center of the view to perform the gesture

The x and y relative percentage is applied first and then from that point, the offset is calculated.

2. Errno::EINTR: Interrupted system call

See the discussion here: calabash/run_loop#35

This is an active issue; no comprehensive solution exists yet.

You can see this error if:

The bundle identifier is incorrect.
The device is not enabled for UIAutomation. Starting in iOS 8, you must enable UIAutomation on the device using the switch in Settings.app > Developer > Enable UIAutomation.

If instruments fails to execute the script using the method below, the problem is on Apple's side of the fence and there is very little we can do besides file bug reports and keep trying to discover the magical ritual that makes it work.

If instruments can execute the script using the method below, then we need to dig deeper into this issue.

Reproduce

Install your app on the problem device; it can be any app that you have the bundle identifier for.
Make a note of your device identifier.
