Short: The Images in my view are not updating after the first load. The URL remains the same as the previous loaded view, however the rest of the view that doesn't fetch a URL or data from storage is updated.
Full: I have two Views, a ListView
and a DetailView
.
In the ListView
I display a list of type List
. The detail view is supposed to show each Profile
from List.profiles
. I do this by storing each string uid
in List.profiles
and calling model.fetchProfiles
to fetch the profiles for each list selected.
On the first selected List
model.fetchProfiles
returns the documents and model.profiles
displays the data fine in the DetailView
.
When first loading the DetailView
the ProfileRow
on appear is called and logs the profiles fetched. Then the ProfileRow
loads the imageURL
from the imagePath
and uses it like to fetch the image.
Console: Load List1
CARD DID APPEAR: Profiles []
CARD DID APPEAR: SortedProfiles [] CARD ROW
CARD ROW DID APPEAR: Profiles profiles/XXXXXX/Profile/profile.png
CARD ROW DID APPEAR: SortedProfiles profiles/XXXXXX/Profile/profile.png
Get url from image path: profiles/XXXXXX/Profile/profile.png
Image URL: https://firebasestorage.googleapis.com/APPNAME/profiles%XXXXXXX
When selecting the second List
from ListView
the ProfileRow
didAppear
is not called due to;
if model.profiles.count > 0 {
print("CARD ROW DID APPEAR: Profiles \(model.profiles[0]. imgPath)")
print("CARD ROW DID APPEAR: Sorted \(model.sortedProfiles[0].imgPath)")
}
and won't ever again when selecting a List
in ListView
, however the rest of the profile data in the ProfileRow
is displayed such as name so the data must be fetched.
The ImagePath
is the same as the first view loading the exact same image. All other properties for the Profile
such as name are loaded correctly.
Console: Load List2
CARD DID APPEAR: Profiles []
CARD DID APPEAR: SortedProfiles [] CARD ROW
Get url from image path: profiles/XXXXXX/Profile/profile.png Image URL: https://firebasestorage.googleapis.com/APPNAME/profiles%XXXXXXX
If I then navigate to List1
then the image for List2
appears, if I reselect List2
the image appears fine. The image show is correct on first load, and when selecting another list it always the one from before.
Can anyone help me out ?

Model

}
func fetchData() {
if let currentUser = Auth.auth().currentUser {
email = currentUser.email!
db.collection("lists")
.whereField("createdBy", isEqualTo: currentUser.uid)
.addSnapshotListener { (querySnapshot, error) in
guard let documents = querySnapshot?.documents else {
return
}
self.lists = documents.compactMap { queryDocumentSnapshot -> List? in
return try? queryDocumentSnapshot.data(as: List.self)
}
}
}
}
func fetchProfiles() {
profiles.removeAll()
for p in list!.profiles {
firestoreManager.fetchProfile(uid: t, completion: { [self] profile in
profiles.append(profile)
})
}
}
}
Update
What I have tried so far is to use didSet
for the ImgPath
or ImgURL
but still not luck. Also have tried using model.profiles
directly.
