  • SR-631 Extensions in different files do not recognize each other

Issue Description:

Extending a class/struct (B) which was declared within an extension of a class/struct (A) OUTSIDE of the original swift file results in "B is not a member of A".

Example:

FileA.swift:

<span color="#dc3e9f">struct</span> Foo {}  
<span color="#dc3e9f">extension</span> Foo {  
    <span color="#dc3e9f">struct</span> Bar {}  
}

<span color="#dc3e9f">extension</span> Foo.Bar {  
    <span color="#14892c">This works</span>  
}

FileB.swift:

<span color="#d04437">!![]( 'Bar' is not a member type of 'Foo' )!</span>  
<span color="#dc3e9f">extension</span> Foo.Bar {  
    <span color="#14892c">This doesn't</span>  
}

A longstanding bug that's been nontrivial to fix. :-(
