xcode 8.1 debug symbols missing
<p>When generating projects with swift package manager (specifically <a href="https://github.com/PerfectlySoft/PerfectTemplate.git" rel="nofollow noreferrer">https://github.com/PerfectlySoft/PerfectTemplate.git</a>) that have an executable (a main.swift), I loose the ability to access local debug symbols when using Xcode 8.1 and later (see below, image 1). Is this specific to the PerfectTemplate and/or is there a fix I can implement? </p>

<p>I've tried this on Xcode 8.1 and 8.2, Swift 3.0.1 and 3.0.2 PREVIEW 1. Also, my optimization level is set to none (see below, image 2). This was not a problem prior to Xcode 8.1, that is, at the same breakpoint shown below the local symbol table did populate. Also, when I lldb the swift build directly for the perfect template executable, the local symbol populates for 3.0.2 but not for 3.0.1 (see below, image 3). And finally, for all other non-executable Xcode projects, SPM or otherwise, both Xcode versions and Swift versions debug properly and generate the local symbol table.</p>
