Realm First User in Static function
My user info only will have a single record so how do I return just the first record from a static function?
If I add realm.objects(UserInfo.self).first it will give me:
Cannot convert return expression of type 'UserInfo?' to return type 'Results<UserInfo>?'
my static function to get the user information:
static func getUserInfo() -> Results<UserInfo>? {
do {
let realm = try Realm()
var userInfo = realm.objects(UserInfo.self)
return userInfo
} catch {
return nil
}
}
Swift and Realm are both new to me - so thanks!

The return type of your static function does not match your intention. Results<UserInfo>? is a Collection (very similar to an Array). If you want the single UserInfo object the return type should be UserInfo?:
static func getUserInfo() -> UserInfo? {
do {
let realm = try Realm()
return realm.objects(UserInfo.self).first
} catch {
return nil
}
}
