Imebra can load local DICOM files or from remote PACS (using the DIMSE protocol).

Imebra cannot load an image directly from an URL because it uses a posix call to open the local file.

To open a file from an URL you should first load the remote file. See this answer Simple Swift file download with URL to see how to load a file to a local temporary file.

Alternatively, you could load the file to a NSData object and pass its content to an Imebra Memory object, then pass to ImebraCodecFactory a StreamReader using a MemoryStreamInput.
