Auto RTL, LTR constraints behavior
<p>Leading and Trailing constrains behaives depending on device langauge direction. To create an app that only support english requires to select every trailing/leading constraint and disable the respect language direction features. that converts the constraints to left/right constraints.</p>

<p>I remember that I used to disable creating leading/trailing constraints by default. instead, my constraints created as left/right constrains by default.</p>

<p>I am not quite sure how I used to do that. I thought that its related to the Use Base Internationalization feature in the project general settings. That didn't work.</p>

<p>I remember before that the project by default disables the Use Base Internationalization feature in older xcode versions. now its enabled by default.</p>

<p>Any idea how I can automatically force left/right constraints instead of leading/trailing constraints?</p>

<p><strong>Edit:</strong>
I just run an app that use base internationalzation and the constraint is leading/trailing and it didnt go RTL even that the device language is Arabic!</p>
