I am following this guide:

but when I get to the step that says to run expo run:ios it fails with the following errors:

I'm not sure what I'm doing wrong Xcode says the following statement
CommandError: Failed to build iOS project. "xcodebuild" exited with error code 65.
I have the latest expo cli installed
I tried building the project in Xcode directly, the project did build, but it won't launch on the emulator, expo opens but when connecting to the dev server the app just crashes.
I do not understand why running expo run:ios results in a build failure while building in Xcode results in a "success".
The solution is actually kind of silly,
so the reason I was able to build successfully in Xcode vs not build successfully using expo run:ios is because I have two version of Xcode installed on this machine. one version is Xcode 12.3, and xcrun was pointed to that sdk package. I was able to fix this by running sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer double checking xcrun --show-sdk-path should now list the appropriate pathing. for good measure I deleted the pods file and the pod.lock file and rebuilt the app using expo run:ios
I just upgrade my game to Unity 2019.2.0f1 and Admob 3.18.2
Now it crashes when I load smart banner (other adsize works fine).
Here is the log:

There's a thread on googleads-mobile-unity github about this issue:
https://github.com/googleads/googleads-mobile-unity/issues/987
One of contributors replied:
I recommend using Unity version 2019.1.11f1 until we determine the cause of
this. We believe it could be a Unity issue, as the Smart banner reference
is null even when proguard is off.
The solution of luvjungle and more specifically the comment of Juan Bentel worked like a charm for me
"Another one posted a working fix! GetAdSizeJavaObject inside Assets/GoogleMobileAds/Platforms/Android/Utils.cs seems to be broken. The first return must be changed to: return new AndroidJavaObject(AdSizeClassName, adSize.Width, adSize.Height).GetStatic("SMART_BANNER"); – Juan Bentel Aug 11 at 8:03 "
def show(conn, %{"id" => id}) do
with {:ok, user} <- UserAction.get_user(id)
|> put_status(200)
|> render("show.json", %{user: user})
else
{:error, :not_found} -> {:error, :not_found, %User{id: id}}
end
end
When id is invalid, Ecto raises:
Ecto.Query.CastError - cannot be dumped to type :binary_id in query.
My get_user function:
query = from(u in User, where u.id == ^id)
case Repo.all(query) do
[%User{} = user] -> {:ok, user}
_ -> {:error, :not_found}
end
Is there any convenient way for handling this error to prevent 500 responses?
That's a known issue with UUID, Binary and other ecto types that need to conform to a specific standard (It's a feature, not a bug™️). Like #TheAnh mentioned, you can use Ecto.UUID.dump/1 to check if the id is valid, but I prefer straight-up rescuing it:
def get_user(id) do
Repo.get(User, id)
rescue
Ecto.Query.CastError -> nil
end
Override Repo
The above example can get tedious because you'll have to rescue everywhere you call get. So I override the get/3 function in MyApp.Repo:
# lib/my_app/repo.ex
defoverridable [get: 2, get: 3]
def get(query, id, opts \\ []) do
super(query, id, opts)
rescue
Ecto.Query.CastError -> nil
end
Use fetch for Tuple format
You should use fetch_* method names instead of get_* to return values in tuple format (to avoid confusion with default Repo methods):
# lib/my_app/repo.ex
def fetch(query, id, opts \\ []) do
case get(query, id, opts) do
nil -> {:error, :not_found}
schema -> {:ok, schema}
end
end
And call it like this in your main function:
def fetch_user(id) do
Repo.fetch(User, id)
end
I've ended up with guard macros
defmacro is_uuid(value) do
quote do
is_binary(unquote(value)) and byte_size(unquote(value)) == 36 and
binary_part(unquote(value), 8, 1) == "-" and binary_part(unquote(value), 13, 1) == "-" and
binary_part(unquote(value), 18, 1) == "-" and binary_part(unquote(value), 23, 1) == "-"
end
end
Usage:
def get_user(id) when is_uuid(id) do
Repo.get(User, id)
end
def get_user(_id), do: {:error, :not_found}
To return 400 you need to update the conn with the appropriate status and then render.
conn
|> put_status(:not_found)
|> put_view(YourApp.ErrorView)
|> render("404.html")
This would be carried out in the else clause of your with expression. You can take this idea further with custom errors: https://hexdocs.pm/phoenix/errors.html
I would advise to check if the input is invalid before operating on it if possible.
There are a few ways you. could validate prior to trying to execute a db query. One solid way is try and cast the value before attempting the query.
iex(1)> Ecto.UUID.cast("no good")
:error
iex(2)> Ecto.UUID.cast("xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx")
:error
iex(3)> Ecto.UUID.cast("de851708-7f7a-40e1-b8ec-da2baec30839")
{:ok, "de851708-7f7a-40e1-b8ec-da2baec30839"}
Given the above behavior above you can wrap your with expression in a case expression. Though, I'm not sure I would use with here either, it's better for pipelines.
case Ecto.UUID.cast(id) do
:error ->
conn |> put_status(400) |> render("error.json", %{message: "Some Message"})
{:ok, uuid} ->
case UserAction.get_user(uuid) do
{:ok, user} ->
conn |> put_status(200) |> render("show.json", %{user: user})
_ ->
conn |> put_status(404) |> render("error.json", %{message: "User not found"})
end
end
Thanks to #vlad-horbachevsky answer, I extended it to my version of guard function:

My requirement is to find the location of a particular string in a line from notepad file but while reading it in powershell additional space get added that's why not able to find the location of a particular string. How I can find the location is this case??
I am using this code for achieving this

foreach ($line in $data)
{
$l =$line.IndexOf("12/29/2015")
write-host $l
}
