Laravel 5.5. - Property [xxxx] does not exist on this collection instance - laravel-5.5

Question

I created two methods that make sql requests that i want to share to all views in my backoffice :
public function getEntities()
{
$vcs = Valuechain::select('valuechains.id', 'lang_valuechain.vcname', 'lang_valuechain.vcshortname')
->withCount('segments')
->join('sectors', 'valuechains.sector_id', '=', 'sectors.id')
->join('lang_valuechain', 'valuechains.id', '=', 'lang_valuechain.valuechain_id')
->join('langs', 'lang_valuechain.lang_id', '=', 'langs.id')
->where('langs.isMainlanguage', '=', '1')
->whereNull('valuechains.deleted_at')
->whereNull('sectors.deleted_at')
->get();
return $vcs;
}
public function getEntitiesWithKeyneeds()
{
$valuechains = Valuechain::orderBy('valuechains.id')
->join('lang_valuechain', 'valuechains.id', '=', 'lang_valuechain.valuechain_id')
->join('langs', 'lang_valuechain.lang_id', '=', 'langs.id')
->where('langs.isMainlanguage', '=', '1')
->with('segments')
->with('keyneeds')
->withCount('segments')
->withCount('keyneeds')
->get();
foreach ($valuechains as $valuechain) {
$ids[] = $valuechain->id;
}
foreach ($ids as $id) {
$vcskns[] = Segment::select(
'lang_valuechain.vcname', 'lang_valuechain.vcshortname',
'lang_segment.segname', 'lang_segment.segshortname', 'segments.id',
'lang_segment.created_at', 'lang_segment.updated_at', 'lang_segment.deleted_at'
)
->distinct()
->withCount('keyneeds')
->join('lang_segment', 'segments.id', '=', 'lang_segment.segment_id')
->join('valuechains', 'segments.valuechain_id', '=', 'valuechains.id')
->join('lang_valuechain', 'valuechains.id', '=', 'lang_valuechain.valuechain_id')
->join('sectors', 'valuechains.sector_id', '=', 'sectors.id')
->join('lang_sector', 'sectors.id', '=', 'lang_sector.sector_id')
->join('langs', 'lang_valuechain.lang_id', '=', 'langs.id')
->where([
['langs.isMainlanguage', '=', '1'],
['valuechains.id', '=', $id]
])
->whereNull('valuechains.deleted_at')
->whereNull('sectors.deleted_at')
->whereNull('segments.deleted_at')
->get();
}
return $vcskns;
}
I call this method in another method which returns a view :
public function index(EntityInterface $vcs)
{
$entitiesLists = $vcs->getEntities();
$entitiesWithKnLists = $vcs->getEntitiesWithKeyneeds();
return view('admin.home', compact('entitiesLists', 'entitiesWithKnLists'));
}
I have a var_dump which returns for entitiesWithKnLists :
[
{
"vcname":"VC1",
"vcshortname":"VC1",
"segname":"S1",
"segshortname":"S1",
"id":1,
"created_at":"2018-06-07 09:18:31",
"updated_at":"2018-06-07 09:18:31",
"deleted_at":null,
"keyneeds_count":0
},
{
"vcname":"VC1",
"vcshortname":"VC1",
"segname":"S2",
"segshortname":"S2",
...
},
{
"vcname":"VC2",
"vcshortname":"VC2",
"segname":"S3",
"segshortname":"S3",
...
},
]
In my view vcname is repeated and i want to display it only once so I wrote in my view the following code :
#foreach($entitiesWithKnLists as $entitiesWithKnList)
{{ $entitiesWithKnList->first()->vcname }}<br>
#endforeach
It returns the correct values I expect.
When i want to display "segname" as we can see in the var_dump, I just write something similar :
#foreach($entitiesWithKnLists as $entitiesWithKnList)
{{ $entitiesWithKnList->segname }}
#endforeach
I obtain an error message :
Property [segname] does not exist on this collection instance.
Thanks

I finally solved the issue this way :
#foreach($entitiesWithKnLists as $entitiesWithKnList)
{{ $entitiesWithKnList->first()->vcname }}
#for ($i=0; $i< count($entitiesWithKnList); $i++ )
{{ $entitiesWithKnList[$i]->segname }}
#endfor
#endforeach
