Download the Data from URL with Header & Body Parameter in Swift 4


Download the Data from URL

Some time we need to download the data from URL like PDF file, word file , CSV file etc. Most of server required the parameter in header so we need to provide the data through header after that he will provide the final url to download , if the all required value passes correctly then it will automatically downloaded to your provided file path.

Here I have used Local file directory where we are storing all this files.


1: We need to declare the request URL & File name:

like that: here i am downloading .pdf file



self.load() -> is function  which make request .

Here we are downloading .pdf file but you can download any file by adding the extension of file.


2: Now we have to make HTTP request to server and download to local directory.


Note: tempUrl – is path of file directory where the actual data is there so we are fetching the data and write to file .

Now you can see the file also by fetching your file manager.
